Oddanier Mosqueda will get start for Red Sox in spring opener against Northeastern on Friday

Left-hander Oddanier Mosqueda will get the start for the Red Sox in their seven-inning exhibition opener against Northeastern at JetBlue Park on Friday, manager Alex Cora announced earlier Tuesday afternoon.

Mosqueda, 23, received an invite to big-league spring training after re-signing with the Red Sox in November. The southpaw is coming off a 2022 season in which he posted a 4.30 ERA and 4.05 FIP with 76 strikeouts to 20 walks over 45 relief appearances (58 2/3 innings) for Double-A Portland.

Among the 99 Eastern League pitchers who tossed 50 or more innings last year, Mosqueda ranked 13th in strikeouts per nine innings (11.66), 11th in strikeout rate (31.4 percent), 22nd in batting average against (.211), 22nd in WHIP (1.12), 22nd in groundball rate (46 percent), 28th in line-drive rate (17.3 percent), 28th in swinging-strike rate (13.8 percent), and eighth in xFIP (3.40), per FanGraphs.

A native of Venezuela, Mosqueda originally signed with the Red Sox as an international free agent in July 2015. The Caracas product is currently regarded by SoxProspects.com as the No. 48 prospect in Boston’s farm system, which ranks 18th among pitchers in the organization.

At 5-foot-10 and 155 pounds, Mosqueda throws from a low three-quarters arm slot and operates with a three-pitch mix that consists of a 90-92 mph fastball that tops out at 94 mph, a 78-80 mph curveball that features 1-to-7 break, and an 83-84 mph changeup that is on the firm side, according to his SoxProspects.com scouting report.

Earlier this month, Chad Jennings of The Athletic identified Mosqueda as a potential dark-horse to make an impact out of the bullpen in 2023, noting that the lefty “has been singled out by one Red Sox evaluator as a legitimate big league possibility this season.”

As currently constructed, the Red Sox are slated to carry just two left-handed relievers on their Opening Day roster next month in Richard Bleier and Joely Rodriguez. Last year, they carried three, all of whom are no longer with the team in Austin Davis, Jake Diekman, and Matt Strahm. They also traded Josh Taylor (who missed all of 2022 with back issues) to the Royals for infielder Adalberto Mondesi in January.

Given that he has yet to pitch above the Double-A level, it seems likely that the Red Sox would want Mosqueda — who turns 24 in May — to experience the ups-and-downs that Triple-A competition offers before they consider a big-league call-up.

If he is able to find success in Worcester to start the season, though, then perhaps Mosqueda will be on Boston’s radar sooner rather than later.

Red Sox agree to two-year, $32 million deal with veteran closer Kenley Jansen, per report

The Red Sox have agreed to terms on a two-year, $32 million contract with free agent reliever Kenley Jansen, according to ESPN’s Jeff Passan. The deal — which is pending a physical — would pay Jansen $16 million in both 2023 and 2024, per The Boston’s Globe Alex Speier.

Jansen, 35, is a veteran of 13 big-league seasons who is best known for his time in Los Angeles. After spending the first 12 years of his career in Los Angeles, the right-hander signed a one-year, $16 million deal with the Braves back in March.

In 65 relief appearances for Atlanta, Jansen posted a 3.38 ERA and 3.21 FIP to go along with 85 strikeouts to 22 walks over 64 innings of work. He also recorded a National League-best 41 saves in 48 opportunities and allowed one run in two outings against the Phillies in the National League Division Series.

A native of Curacao, Jansen originally signed with the Dodgers as a catcher in November 2004. He spent the first 4 1/2 seasons of his minor-league career behind the plate before transitioning to the mound midway through the 2009 campaign. The following July, Jansen made his major-league debut for Los Angeles.

It did not take long for Jansen to establish himself as one of the top relievers in baseball. He finished seventh in National League Rookie of the Year voting in 2011 and registered his first season of 25 or more saves in 2012. From 2016-2018, the righty forged a 2.07 ERA and 2.29 FIP across 205 outings (208 2/3 innings) and made three consecutive All-Star teams. His 350 saves in a Dodgers uniform are the most in the franchise’s storied history.

Between Los Angeles and Atlanta, Jansen owns a lifetime 2.46 ERA and 2.44 FIP with 1,107 strikeouts to 226 walks over 766 relief appearances spanning 769 innings pitched. He ranks eighth in American/National League history with 391 career saves. In 10 separate trips to the postseason during that stretch, Jansen produced a 2.29 ERA over 59 total outings out of the bullpen.

Listed at 6-foot-5 and 265 pounds, Jansen operates with a three-pitch mix that consists of an elite cutter (his primary weapon), a sinker, and a cutter. This past season, he ranked in the 98th percentile of the league in expected batting average (.169), the 93rd percentile in expected slugging percentage (.292), the 93rd percentile in strikeout rate (32.7 percent), the 95th percentile in fastball spin, and the 93rd percentile in extension, according to Baseball Savant.

Jansen, who does not turn 36 until next September, does come with some concerns. Earlier this summer, he spent more than two weeks on the injured list due to an irregular heartbeat, which is something that has sidelined him in the past. He has had two cardiac ablation procedures (2012 and 2018) to combat this issue.

With the addition of Jansen, the Red Sox have made it clear that bolstering the bullpen was one of the club’s top priorities this winter after Boston relievers finished with the second-worst ERA (4.59) in the American League this season. Chief baseball officer Chaim Bloom and Co. have already signed left-handed reliever Joely Rodriguez to a one-year contract last month and agreed to terms on a two-year $17.5 million deal with righty Chris Martin last week.

Assuming he passes his physical, Jansen will become the first established closer the Red Sox have had since Craig Kimbrel left the club after winning the World Series in 2018. Jansen, Rodriguez, and Martin are slated to join a bullpen mix that is highlighted by the likes of Matt Barnes, Tanner Houck, John Schreiber heading into 2023.

Red Sox closer Tanner Houck shut down from throwing due to continued back soreness

Red Sox closer Tanner Houck was slated to throw live batting practice in Worcester on Tuesday. That did not happen as scheduled.

Houck, who has been on the injured list with lower back inflammation since August 6, is now “on hold” from throwing “because of continued back soreness,” manager Alex Cora told reporters (including The Boston Globe’s Pete Abraham) before Tuesday’s game against the Twins.

Two weeks ago, Houck was diagnosed with a disc issue in his lower back after being examined by a spine specialist in Boston. Following a brief period of rest, the right-hander resumed playing catch again at Fenway Park last week after responding well to treatment.

“He’s got the green light to keep going,” Cora said last Tuesday. “We just have to build him up and see how it goes. The hope is for him to get back at one point this season. He feels strong. The treatment has been good. It’s just the start now. He feels good enough to keep going.”

Despite those positive steps, it now appears as though Houck’s availability for the rest of the year is in question. With only five weeks left until the regular season ends, the Red Sox could very well elect to shut down the 26-year-old hurler as their playoff hopes continue to dwindle.

Houck began the 2022 season in Boston’s starting rotation and started four games before moving to the bullpen on a full-time basis on May 15. Since then, the righty has posted a 1.49 ERA and 3.18 FIP with 33 strikeouts to 11 walks over 25 relief appearances spanning 36 1/3 innings of work. He has also gone 8-for-9 in save opportunities.

While Houck has been sidelined, the Red Sox have had to look elsewhere in regards to closing out games. Since Houck last pitched on Aug. 2, Garrett Whitlock has recorded a team-high three saves while Matt Barnes has notched two and John Schreiber has picked up one.

Red Sox promote Zack Kelly, Kaleb Ort from Triple-A Worcester; Austin Davis, Hirokazu Sawamura designated for assignment

UPDATE: This is now official. The Red Sox have called up Kelly and Ort from Triple-A Worcester and have designated Davis and Sawamura for assignment, the club announced before Monday’s series opener against the Twins.

Kelly will wear the No. 76, becoming just the fourth player in franchise history to do so and the first since Hector Velazquez donned the number from 2017-2019.

After designating Austin Davis and Hirokazu Sawamura for assignment on Sunday, the Red Sox are expected to call up right-handers Zack Kelly and Kaleb Ort from Triple-A Worcester, according to multiple reports.

Kelly and Ort will join the Red Sox and their new-look bullpen in Minnesota ahead of Monday’s series opener against the Twins at Target Field. The former will need to be added to Boston’s 40-man roster while the latter is already on it.

When Kelly gets into a game, it will mark his major-league debut. The 27-year-old has spent the last two seasons in the Red Sox organization after originally signing a minor-league deal with the club last January. Prior to that, Kelly had gone undrafted out of Division II Newberry College (Newberry, S.C.) and signed with the Athletics for just $500 in January 2017.

After splitting time between the Athletics and Angels organizations, Kelly suffered an elbow injury in the spring of 2020 that would ultimately require surgery. He was released by Los Angeles that May in the midst of the COVID-19 shutdown.

Since then, however, Kelly has only seen his stock rise. The native Virginian posted a 2.18 ERA over 36 appearances (45 1/3 innings) between Double-A Portland and Triple-A Worcester last year and leveraged that performance into his first-ever invite to big-league spring training after re-signing with the Red Sox in November.

With the WooSox this season, Kelly has pitched to a stellar 2.72 ERA and 2.81 FIP to go along with 72 strikeouts to 25 walks over 44 relief appearances spanning 49 2/3 innings of work. The 6-foot-3, 205-pound hurler operates with a three-pitch mix that consists of a high-90s fastball, a low-80s changeup, and a high-80s cutter.

Ort, who debuted for Boston last September, has produced a 9.00 ERA and 4.06 FIP with 13 strikeouts and seven walks across 12 outings (15 innings) at the major-league level this season. The Red Sox originally acquired the 30-year-old from the Yankees in the minor-league phase of the 2020 Rule 5 Draft.

Frequently pitching behind Kelly in Worcester, Ort owns a 2.88 ERA (2.68 FIP) in 39 appearances for the WooSox this year. He has put up those numbers while converting 16 of a possible 18 save opportunities.

When Davis and Sawamura are officially designated for assignment and Kelly and Ort are officially called up, the Red Sox will have 26 players on their 26-man roster and 39 players on their 40-man roster. At this point in time, it is not yet known how they will use that open spot.

Red Sox to designate Austin Davis for assignment, per report

The Red Sox are going to designate left-hander Austin Davis for assignment before Monday’s game against the Twins in Minnesota, according to The Athletic’s Chad Jennings.

Davis, 29, has posted a 5.47 ERA and 3.95 FIP to go along with 61 strikeouts to 29 walks over 50 appearances (three starts) spanning 54 1/3 innings of work for the Red Sox this season.

Boston originally acquired Davis from the Pirates in the trade that sent Michael Chavis to Pittsburgh last July. Red Sox manager Alex Cora frequently turned to the lefty reliever during the latter half of the 2021 season and that remained to be the case this year.

To begin his first full season in Boston, Davis produced a solid 2.16 ERA and 3.46 FIP with 36 strikeouts to 16 walks across his first 31 outings (two starts) and 33 1/3 innings pitched through July 7. He was putting up those numbers while holding opposing hitters to a .202/.309/.294 slash line against.

Since July 8, however, Davis has struggled to the tune of a 10.71 ERA with 25 strikeouts to 13 walks in his last 19 appearances (one start) and 11 innings. He allowed four runs (two earned) on three hits, one walk, and one punchout over two innings of relief in Sunday’s 12-4 loss to the Rays at Fenway Park.

Davis, who turns 30 in February, is out of minor-league options. The Red Sox will have the next seven days to either outright or release the Arizona native. If he clears waivers, however, Davis could reject an outright assignment to the minor-leagues in favor of free agency since he has already accrued more than three years of big-league service time.

By designating Davis for assignment, the Red Sox have created an opening on both their 26- and 40-man rosters. It remains to be seen how they will fill those spots, though they are required to carry 13 pitchers until rosters expand on Thursday.

If the Sox elect to fill Davis’ vacancy with a reliever who is already on the 40-man roster, Darwinzon Hernandez and Kaleb Ort are potential options who are currently with Triple-A Worcester. Tyler Danish was just optioned to Worcester on Sunday so he can not be called back up for the next 15 days unless he is replacing an injured player.

If Chaim Bloom and Co. look beyond the 40-man roster for Davis’ replacement, The Boston Globe’s Alex Speier reports that there is ‘a good chance’ right-hander Zack Kelly gets called up to replace Davis in the bullpen.

Kelly, 27, has spent the last two years in the Red Sox organization after signing a minor-league deal with the club last January. In 44 appearances for the WooSox this season, the 6-foot-3, 205-pound hurler has pitched to a 2.72 ERA (2.81 FIP) with 72 strikeouts to 25 walks across 49 2/3 innings of work.

Red Sox’ Matt Strahm likely to be activated from injured list for Friday’s series opener against Orioles, Alex Cora says

UPDATE: Strahm told The Boston Globe’s Alex Speier he expected to be activated before Friday’s series opener against the Orioles in Baltimore. A corresponding roster move will need to be made.

—–

There is a “good chance” Red Sox reliever Matt Strahm returns from the injured list and joins the team in Pittsburgh on Thursday, manager Alex Cora told reporters (including The Boston Globe’s Pete Abraham) prior to Wednesday’s game against the Pirates.

Strahm has been sidelined since July 12. That night, the left-hander took a 98 mph line drive off his throwing hand from Taylor Walls in the sixth inning of a 3-2 loss to the Rays at Tropicana Field. He was immediately removed from the game and was later diagnosed with a left wrist contusion, though x-rays did come back negative.

Three days later, Strahm was placed on the 15-day injured list (retroactive to July 13) with said contusion. The 30-year-old southpaw began throwing again earlier this month and was sent out on a brief rehab assignment with Triple-A Worcester on Tuesday night.

In what will likely be his lone appearance for the WooSox, Strahm struck out one of the three batters he faced in a scoreless sixth inning against the Rochester Red Wings at Polar Park. He needed just 14 pitches (9 strikes) to get through the perfect frame and was hovering around 94-95 mph with his fastball, per Cora.

Signed to a one-year, $3 million deal back in March, Strahm has posted a 3.58 ERA and 2.61 FIP to go along with 32 strikeouts to seven walks over 33 relief appearances spanning 27 2/3 innings of work for Boston.

Strahm’s return would be a welcomed one for the Red Sox. As things stand currently, Austin Davis is the only active lefty in Boston’s bullpen. Davis owns an ERA of 13.15 in his last 15 outings dating back to July 8.

Red Sox release Hansel Robles

The Red Sox have released veteran reliever Hansel Robles, the team announced earlier Saturday afternoon.

Robles was designated for assignment on Wednesday so that top pitching prospect Brayan Bello could be added to the big-league roster ahead of his big-league debut. The move also created a space on the 40-man roster for the addition of Michael Feliz, who has since been designated for assignment himself.

Originally acquired from the Twins at last year’s trade deadline in exchange for Alex Scherff, Robles quickly became one of Alex Cora’s most trusted relievers during the latter half of the 2021 season. After making 14 straight scoreless appearances in September and being heavily relied upon during the playoffs, Robles was brought back on a minor-league contract in March.

It was therefore no surprise that the 31-year-old right-hander made Boston’s Opening Day roster out of spring training, thus locking him into a guaranteed salary of $2.25 million for the 2022 campaign.

Robles got his first full season in a Red Sox uniform off to a solid start, allowing just one earned run across nine April appearances. Things began to take a turn for the worst in May, though, and those struggles were compounded by a trip to the injured list (back spasms) that lasted about two weeks.

Upon returning from the IL on June 9, Robles gave up runs in five of his next 10 outings, bringing his ERA on the season up to 5.84 and his FIP up to 5.74. During this rough stretch, Robles’ fastball velocity was down from where it usually was. He lost his spot on the 40-man roster after giving up a run in the seventh inning of Tuesday night’s 8-4 loss to the Rays at Fenway Park.

Given the fact that any team that claimed Robles would be on the hook for the rest of his 2022 salary, it was not surprising to see that the Dominican-born righty cleared waivers. Since he has accrued enough major-league service time, he exercised his right to reject an outright assignment to the minor-leagues in favor of free agency.

Now free to sign with whichever club he chooses, Robles will still be collecting from the Red Sox until the end the season.

Red Sox select Kaleb Ort from Triple-A Worcester, designate Michael Feliz for assignment

The Red Sox have selected the contract of right-handed reliever Kaleb Ort from Triple-A Worcester. In a corresponding move, fellow right-hander Michael Feliz has been designated for assignment, according to MassLive.com’s Chris Cotillo.

Ort is expected to be activated ahead of Saturday’s game against the Yankees at Fenway Park. The 30-year-old made his major-league debut for Boston last September, appearing in one game as a COVID-related substitute while the club was in Seattle.

Originally acquired from the Yankees in the minor-league phase of the 2020 Rule 5 Draft, Ort has spent the vast majority of the last two seasons with the WooSox. This year alone, the Michigan-born righty has posted a 3.12 ERA and 2.62 FIP with 47 strikeouts to 16 walks over 33 relief appearances spanning 34 2/3 innings of work.

Undrafted out of Aquinas College in Grand Rapids, Ort initially signed with the Diamondbacks out of independent ball in 2016 but was released the following spring. He then latched on with the Yankees in May 2017 and spent the next three-plus years in the organization before getting scooped up by the Red Sox in December 2020.

Listed at 6-foot-4 and 240 pounds, Ort may not be much of a prospect at this point, but he has still proven to be an effective weapon out of Worcester’s bullpen the last two seasons thanks to a two-pitch mix that consists of a high-90s fastball and whiff-inducing slider.

Feliz, meanwhile, was added to Boston’s 40-man roster on Thursday and made his 2022 debut in Friday’s 12-5 loss to the Yankees. The 29-year-old relieved starter Connor Seabold and allowed two runs (one earned) on one hit, two walks, and four strikeouts over 3 1/3 innings. Thirty-four of the 57 pitches he threw went for strikes.

The Sox will now have the next seven days to either trade, release, or waive Feliz, who has accrued enough service time to reject an outright assignment to the minor-leagues in favor of free agency.

Red Sox place Matt Strahm on COVID-19 related injured list, recall Hirokazu Sawamura from Triple-A Worcester

Before wrapping up their five-game series against the Orioles at Fenway Park on Monday night, the Red Sox placed left-handed reliever Matt Strahm on the COVID-19 related injured list.

In a corresponding move, right-handed reliever Hirokazu Sawamura was recalled from Triple-A Worcester, the team announced.

At this time, it is not yet clear if Strahm has tested positive for COVID-19 or is simply experiencing virus-like symptoms. Through 18 relief appearances this season, the 30-year-old southpaw has posted a 3.68 ERA and 1.77 FIP with 16 strikeouts to three walks over 14 2/3 innings of work.

Sawamura, meanwhile, returns from Worcester after being optioned there on Saturday. Unsurprisingly, the Japanese-born righty did not get into a game with the WooSox. This season with the big-league club, he has produced a 3.60 ERA and 3.47 FIP to go along with 13 strikeouts to six walks across 18 appearances spanning 15 innings pitched.

Following Monday’s roster move, the Red Sox will now be without Strahm and Hansel Robles (on the 10-day injured list due to back spasms) for the time being. Alex Cora’s bullpen currently consists of the likes of Sawamura, Matt Barnes, Jake Diekman, Austin Davis, John Schreiber, Tyler Danish, Ryan Brasier and Phillips Valdez. Tanner Houck could be included there, too, but he is not available to pitch on Monday, per Cora.

Rafael Devers homers twice as Red Sox erase 5-run deficit and come from behind to beat Mariners, 6-5

The Red Sox once again fell behind early against the Mariners on Saturday but battled their way back at Fenway Park. Boston defeated Seattle by a final score of 6-5 to win their fourth straight game and third consecutive series while improving to 18-22 on the season.

Before the Sox could even take their first at-bats of the afternoon, they already found themselves trailing by four runs. Garrett Whitlock, making his sixth start of the year, allowed the Mariners to score four times in the top half of the first inning.

After getting through a scoreless second inning, the right-hander ran into more trouble in the third by giving up back-to-back two-out hits to Mike Ford and Luis Torrens, which resulted in another Seattle run crossing the plate.

The third would prove to be Whitlock’s final inning of work, as he wound up surrendering a season-high five earned runs on 10 hits, no walks, and three strikeouts on 71 pitches (48 strikes). The 25-year-old’s ERA now sits at 3.58.

To that point in the contest, the Boston lineup had yet to do anything of significance against opposing starter Chris Flexen. That changed in the bottom half of the third though, as Rafael Devers got his productive day at the plate started by crushing a 413-foot solo shot into the bleachers to get his side on the board and make it a 5-1 ballgame.

Fast forward to the fifth, after Tyler Danish had hurled two scoreless frames out of the Sox bullpen, and Devers struck again. Following a leadoff double from Enrique Hernandez, the left-handed slugger took Flexen 386 feet over the Green Monster for his second big fly of the game and ninth of the season.

Devers’ two-run blast, which had an exit velocity of 102.1 mph, cut the deficit down to two runs at 5-3. But the Red Sox were not done there. A J.D. Martinez double and Xander Bogaerts single chased Flexen from the contest and put runners on the corners for Bobby Dalbec, who greeted new Mariners reliever Sergio Romo by lifting an RBI single to center field to drive in Martinez and move Bogaerts up to third. Trevor Story followed with a sacrifice fly that scored Bogaerts to tie things up at five runs apiece.

From there, Jake Diekman punched out the side in the sixth, Hansel Robles worked his way around a two-out double in the seventh, and John Schreiber retired the only three batters he faced in the top of the eighth to keep the 5-5 tie intact.

With one out in the bottom half of the eighth, Franchy Cordero laced a 110.5 mph triple off the Green Monster to put the potential go-ahead run in scoring position for Christian Vazquez, who came through with the game-winning single off Drew Steckenrider that plated Cordero and gave the Sox a 6-5 lead.

Looking to protect that lead, Red Sox manager Alex Cora called upon Matt Barnes to take the mound in the ninth inning. Barnes, in turn, needed just 15 pitches (and a little defensive help from Hernandez) to slam the door shut on the Mariners and notch his second save of the season.

All told, five Boston relievers (Danish, Diekman, Robles, Schreiber, and Barnes) combined to toss six shutout innings in relief of Whitlock on Saturday. The Red Sox lineup, meanwhile, went 4-for-6 with runners in scoring position while putting together their largest comeback win of the season thus far.

Next up: Gilbert vs. Eovaldi in series finale

The Red Sox will look to close out the weekend with a four-game sweep over the Mariners on Sunday afternoon. Veteran right-hander Nathan Eovaldi will get the start for Boston opposite fellow righty Logan Gilbert for Seattle.

First pitch from Fenway Park is scheduled for 1:35 p.m. eastern time on NESN.
