Red Sox trade: infield prospect Christian Koss acquired from Rockies in exchange for left-hander Yoan Aybar

The Red Sox have acquired infield prospect Christian Koss from the Rockies in exchange for left-handed pitching prospect Yoan Aybar. The club made the trade official earlier Thursday evening.

Koss, who turns 23 in January, was selected by Colorado in the 12th round of the 2019 amateur draft out of the University of California, Irvine.

In 53 games with rookie-level Grand Junction of the Pioneer League last year, the Riverside native posted an impressive .322/.447/.605 slash line (172 wRC+) to go along with 11 home runs and 51 RBI over 238 plate appearances.

Named a mid and post-season Pioneer League All-Star thanks to his efforts, Koss opened the 2020 campaign regarded by Baseball America as the Rockies’ No. 29 prospect.

Capable of playing every infield position besides first base at the moment, the right-handed hitting, right-handed throwing Koss is listed at 6-foot-1 and 182 lbs.

Koss is Rule 5 eligible next winter, so the 2021 season will prove to be an important one for him regardless of where he begins the year, which will likely be High-A Salem.

As for Aybar, the now-former Sox prospect was added to Boston’s 40-man roster last November, yet he was the only member of the 40-man roster to not be included in the club’s 60-man player pool this past season.

Originally signed as an outfielder out of the Dominican Republic in 2013, the stout southpaw converted into a pitcher full-time in 2018, most recently posting a 4.61 ERA over 44 relief appearances and 56 2/3 innings pitched between Low-A Greenville and High-A Salem last year.

With Aybar being traded to another organization, the Red Sox’ 40-man roster is currently down to 39 players, with plenty more moves to come as the offseason continues.

Red Sox sign Matt Barnes, 6 others to one-year deals, tender contract to Rafael Devers

UPDATE: As noted by MassLive.com’s Chris Cotillo, the Red Sox also signed right-hander Chris Mazza and outfielder Yairo Munoz to one-year deals on Wednesday.

The non-tender deadline came and went Wednesday night without the Red Sox cutting a single arbitration or pre-arbitration eligible player from its 40-man roster.

Per a team release, the Sox agreed to one-year contracts with the likes of right-handers Austin Brice, Matt Barnes, Ryan Brasier, and Chris Mazza, left-hander Eduardo Rodriguez, and catcher Kevin Plawecki.

Additionally, Boston will tender one-year contracts for the 2021 season to 25 players who remain unsigned, with third baseman Rafael Devers being the most notable of those individuals after the two sides failed to reach agreement on a deal.

The 24-year-old will have until January 15 to come to terms on a contract with the Sox or he will otherwise be headed for salary arbitration for the first time in his career come February.

As for the other players involved here, MassLive.com’s Chris Cotillo has the details on how much Barnes, Brasier, Brice, Mazza, Munoz, Plawecki, and Rodriguez will be earning next season:

Barnes: $4.5 million salary for 2021
Brasier: $1.25 million salary for 2021
Brice: $870,000 salary for 2021
Mazza: $576,000
Munoz: $582,500
Plawecki: $1.6 million salary for 2021
Rodriguez $8.3 million salary for 2021

All in all, the Red Sox owe this group listed above more than $17.5 million headed into the upcoming season.

Barnes, 30, and Rodriguez, 27, are the only two players who were entering their final year of arbitration eligibility, meaning they will become free agents for the first time in their respective careers next winter barring any extension talks.

On account of them not making any sort of cuts or subtractions on Wednesday, Boston’s 40-man roster is still at full capacity. That is likely to change now that this offseason’s free agency class has increased in size due to other clubs non-tendering a staggering amount of their eligible players in order to save money.

Former Red Sox right-hander Robert Stock claimed off waivers by Cubs

A week after he was designated for assignment, former Red Sox right-hander Robert Stock was claimed off waivers by the Cubs earlier Wednesday afternoon.

Stock, 31, was originally claimed off waivers by Boston from the Phillies back in late July.

In his debut season with the Sox, the flame-throwing righty allowed nine runs (seven earned) on 16 hits and 10 walks over 10 relief appearances and 13 1/3 total innings of work spanning three major-league stints. That’s good for a 4.73 ERA, but a 101 ERA+ and 3.34 FIP as well.

Noted for his fastball velocity since being drafted by the St. Louis Cardinals in the second round of the 2009 amateur draft, Stock averaged 96.8 mph with his heater this past season while topping out at 99 mph with the pitch.

Now a member of the Cubs’ 40-man roster, the University of Southern California product will presumably have the opportunity to compete for a spot in Chicago’s Opening Day bullpen.

With the loss of Stock, the Red Sox have now in one way or the other removed 11 pitchers — Stock, Domingo Tapia, Matt Hall, Ryan Weber, Robinson Leyer, Andrew Triggs, Mike Kickham, Kyle Hart, Zack Godley, Dylan Covey, and Martin Perez (player option declined) — from their own 40-man roster since the start of the offseason.

Red Sox outfield prospect Nick Decker ‘could develop into really good platoon player’ at major-league level

As a member of the Red Sox’ 2018 draft class, outfield prospect Nick Decker is often overshadowed by the likes of Triston Casas, Jarren Duran, and even Thaddeus Ward.

That being said, Decker is still one of the premier outfielders in Boston’s minor-league pipeline, as MLB Pipeline ranks the former second-round pick as the organization’s No. 13 overall prospect.

In his first full professional season in 2019, the New Jersey native posted a solid .247/.328/.471 slash line (135 wRC+) to go along with six home runs and 25 RBI over 53 games and 197 plate appearances for short-season Lowell.

Most of the success Decker enjoyed with the Spinners came against right-handed pitching, as the left-handed hitting outfielder clubbed five of his six homers off righties while struggling against southpaws to the tune of a measly .613 OPS.

Fast forward more than a year later and Decker, now 21 years old, endured the same difficulties against lefties at the Red Sox’ fall instructional league in Fort Myers after not being part of the club’s 60-man player pool at any point this past season.

According to SoxProspects.com’s Ian Cundall, Decker “raked against right-handers, but continued to struggle against lefties” during instructs.

Even with that apparent hole in his offensive approach at the moment, all is not lost for Decker, as scouts still seem encouraged by what he can do against right-handed pitching alone.

“Even with his struggles against southpaws, scouts were encouraged by his power and offensive potential against righties,” Cundall wrote. “So much so that they think he could develop into a really good platoon player. ”

Because the highest level of pitching he’s faced in organized games as a professional thus far has been out of the New York-Penn League, Decker’s career trajectory has not yet really come into focus.

At 21, Decker still has room to grow and develop as a baseball player, especially on the defensive side of things.

With two years left before reaching Rule 5 eligibility, the one-time University of Maryland commit will certainly have the time to improve upon those aspects of his game going into the spring.

SoxProspects.com’s projected 2021 rosters have Decker beginning next season at Low-A Greenville of the South Atlantic League.

Red Sox ‘showing interest’ in two-time Cy Young Award winner Corey Kluber, per report

The Red Sox are showing interest in free-agent right-hander Corey Kluber, according to MLB Network’s Jon Morosi.

Kluber, 34, is coming off a 2020 season in which he only made one start and threw one inning for the Rangers on account of suffering a torn right teres muscle against the Rockies on July 26.

Texas had acquired Kluber from the Indians in exchange for outfielder Delino Deshields and pitching prospect Emmanuel Clase last December.

As a result of his only making one start this year, Kluber had his $18 team option declined by the Rangers at the end of October, making him a free agent.

After collecting two American League Cy Young Awards and finishing third or better in A.L. Cy Young voting four times within a five-year span with Cleveland from 2014 through 2018, Kluber has fallen off a bit recently regarding his durability.

Since the start of the 2019 campaign, the three-time All-Star has made just eight starts and accrued 36 2/3 innings of work due to injuries. Last year, he suffered a right ulna fracture in early May, which wound up costing him the rest of the season.

Despite those potential concerns, Kluber was cleared for normal offseason activities back in October and is slated “to be ready to go for spring training,” per WEEI’s Rob Bradford.

As noted by Morosi in the tweet above, Kluber makes his offseason home in the greater Boston area since his wife, Amanda, is a Massachusetts native.

With that connection in mind, Kluber and the Red Sox certainly seem like a possible match, especially if the Texas native was willing to sign a short-term, incentive-laden deal in order to re-establish his value.

Of course, what the veteran righty is seeking in terms of contract details has yet to be revealed, but one thing is for certain: the Red Sox are in need of starting pitching, and for chief baseball officer Chaim Bloom and Co., Kluber certainly fits the bill.

Red Sox catching prospect Connor Wong ‘made a lot of progress’ in 2020, Jason Varitek says

Of the three players the Red Sox acquired from the Dodgers in the infamous Mookie Betts trade back in February, catching prospect Connor Wong is undoubtedly the least well-known and the least heralded.

Alex Verdugo — the headliner of the deal for Boston — has the makings to be an All-Star caliber major-league outfielder, Jeter Downs is the organization’s top prospect, and then there’s Wong.

This isn’t to say the 24-year-old is not a talented prospect, because he is. So much so that MLB Pipeline has him ranked as the top catching prospect in the Sox’ farm system.

In his last minor-league season with the Dodgers in 2019, Wong posted a solid .281/.336/.541 to go along with 24 home runs and 82 RBI over 111 total games played between High-A Rancho Cucamonga and Double-A Tulsa.

The majority of Wong’s playing time last year came behind the plate, but he also proved capable of playing multiple positions around the infield, which is something he did quite frequently at the University of Houston since he was originally recruited as a shortstop.

Despite that added dose of versatility, the Red Sox still view the 2017 third-round pick as a catcher primarily. Newly-promoted game planning coordinator and former Sox backstop Jason Varitek made that much clear when speaking with The Boston Globe’s Pete Abraham last week.

“I saw him a lot, from spring training and spring training 2.0, and probably three weeks when he was on the taxi squad and around the team,” Varitek said of Wong. “He works extremely hard. He didn’t get in any [major-league] games, but he showed his abilities and made a lot of progress. He can play other positions, but I think he’s a catcher. There’s a lot there we can work with.”

Indeed, Wong did not appear in any games for Boston this past season, but as noted by Varitek, he still spent plenty of time around the club during spring training as well as parts of the summer and fall on account of being included on the 60-man player pool for the entirety of the 2020 campaign.

On top of that, the Houston native was added to the Sox’ 40-man roster earlier this month, so it would appear he is primed to make his major-league debut sooner rather than later.

With Wong being added to the 40-man, the Red Sox currently have four catchers — Wong, Deivy Grullon, Kevin Plawecki, and Christian Vazquez — on their major-league roster.

Red Sox prospect Juan Chacon ‘caught some attention’ at fall instructs, Eddie Romero says

Like fellow prospect Chih-Jung Liu, Juan Chacon’s baseball experience in 2020 was anything but normal.

The 17-year-old was likely going to spend the majority of the year playing in the Dominican Summer League, but the ongoing COVID-19 pandemic that caused the minor-league season to be cancelled prevented that from happening.

Instead of getting more exposure in the Dominican, where he played in the Tricky League last summer, Chacon had to wait until early October to get his first real opportunity of 2020.

Up until then, Chacon had been working out a facility in Miami, which likely gave him an edge in preparedness when he received an invite to the Sox’ fall instructional league in Fort Myers.

“It was our official version of seeing him, finally under supervision,” Red Sox assistant general manager Eddie Romero said of Chacon when speaking with WEEI’s Rob Bradford. “He has a tool-set. He is a plus-runner. It was something when we first saw him he kept getting faster every time and by signing day he was running a 6.6 60. He’s got above-average arm strength. We think he’s somebody who can stay in the middle of the field and cover a lot of range. He’s got a strong arm. And offensively, right now he’s got a projectable frame. He’s very athletic. He’s somebody from an offensive standpoint, he uses the whole field.”

The Red Sox signed Chacon, a right-handed hitter, out of Venezuela for $900,000 last July, making him the club’s highest-paid international signee for the 2019-2020 international signing period.

That is quite the investment, and with that investment comes somewhat lofty expectations; expectations which Chacon lived up to at fall instructs.

“He performed well at instructs,” Romero added. “Which for a first-year signee, usually [with those] those guys, there aren’t many of them we push straight to the stateside instructional league. We wanted to see him and he did well and I know he caught some attention.”

Regarded by SoxProspects.com as Boston’s No. 49 prospect, the 6-foot-2, 170 lb. outfielder will have the opportunity to ascend the prospect ranks some more once he actually gets the chance to see some in-game action. That will presumably happen in the rookie-level Gulf Coast League at some point in 2021.

Fall instructs allowed Red Sox prospect Chih-Jung Liu to get ‘into more of a professional routine,’ Ben Crockett says

Chih-Jung Liu’s first exposure to professional baseball in the United States has been hindered by unprecedented circumstances.

The 21-year-old right-handed pitching prospect was originally signed by the Red Sox out of Taiwan for $750,000 last October, and the 2020 season was supposed to serve as his springboard into the organization

Instead, the ongoing COVID-19 pandemic caused plans to change in a variety of ways, as Liu had to quarantine in his Fort Myers hotel room upon arriving from Taipei for spring training in late February.

While the pandemic continued to roll on in the United States as the calendars flipped to March, Major League Baseball was eventually forced to shut down all spring training camps on March 12.

With the majority of players returning to their homes as a result of that decision, Liu, too, decided to go back to Taiwan so he could work out in a familiar environment given all the uncertainties the U.S. was facing at that time.

Liu would remain in his home country until late September, when he made the trek back to Florida after receiving an invitation to participate in the Red Sox’ fall instructional league.

Once fall instructs began the following week, the Red Sox finally had the chance to see what exactly Liu brought to the table over an extended period of time.

Based off what vice president of player development Ben Crockett told The Athletic’s Chad Jennings, the club was quite impressed with what they saw from the right-hander.

“He was in spring training for such a short period of time,” Crockett said of Liu. “[It was] great to actually see him. [He was] really interesting. Showed good stuff. Good fastball with carry. Showed pitch-ability. Showed an ability to use multiple pitches that will ultimately help him. It was definitely nice to kind of get him into more of a professional routine.”

Regarded by MLB Pipeline as Boston’s No. 18 prospect, the 6-foot, 180 lb. hurler operates with a three-pitch mix that includes a 92-96 mph that can top out at 98 mph, an 86-88 mph slider, and a low-80s changeup “with some fade,” per his SoxProspects.com scouting report.

Because so little has been seen of him to this point, it’s difficult to project what Lui’s 2021 season will look like in terms of which minor-league level he starts at.

Wherever he does start out next spring, Liu does figure to work as a starting pitcher for the time being despite the fact he was a two-way player in high school and excelled as a switch-hitting infielder in college while taking a two-year break from pitching.

Red Sox prospect Brainer Bonaci ‘showed a solid blend of instincts and physical ability’ at fall instructs

Brainer Bonaci has been a professional baseball player for just over two years and he doesn’t turn 19 years old until next July, but he is already looking like one of the more exciting young infielders in the Red Sox’ minor-league pipeline.

The 18-year-old shortstop is coming off an impressive showing at the Sox’ fall instructional league in Fort Myers. According to SoxProspects’ Ian Cundall, Bonaci “looked the best of the young shortstops [at fall instructs] and showed a solid blend of instincts and physical ability. He has a plus arm and both his glove and hit tool showed average potential.”

Signed out of Venezuela by Manny Padron and Eddie Romero for $290,000 on his 16th birthday in 2018, Bonaci is starting to get some legitimate attention thanks to what he did this fall.

Had there been a minor-league season in 2020, Bonaci likely would have began the year with the Gulf Coast League Red Sox. Instead, due to the ongoing COVID-19 pandemic, he was limited in what he could do until October, when fall instructs began.

In his only organized action as a minor-leaguer thus far, the 5-foot-10 switch-hitter posted a solid .279/.356/.379 slash line (111 wRC+) to go along with three home runs, 37 RBI, and 18 stolen bases over 61 games played for the Dominican Summer League Red Sox last year.

Because he is still only 18 years old, Bonaci still has plenty of room to grow physically and developmentally. That said, there’s still reason to be excited about his potential, and SoxProspects’ latest prospect rankings reflect that.

Yes, Bonaci is now the No. 14 prospect in Boston’s farm system according to SoxProspects, good for the fifth highest ranking among infielders after Triston Casas, Jeter Downs, Bobby Dalbec, and Nick Yorke.

Going back to April 1, Bonaci was regarded by SoxProspects as the club’s 20th-ranked prospect, so it is clear he is trending in the right direction. And with Dalbec set to graduate from his prospect status next season, it’s safe to assume Bonaci will only continue to rise through the prospect ranks in 2021.

If we look even further ahead, Bonaci will become Rule 5 eligible for the first time in late 2022, so it’s not like he is too far out from garnering 40-man roster consideration as his development continues.

Red Sox claim right-hander Joel Payamps off waivers from Diamondbacks, designate Robert Stock

The Red Sox have claimed right-hander Joel Payamps off waivers from the Arizona Diamondbacks, the club announced Wednesday.

In order to make room for Payamps on Boston’s 40-man roster, right-hander Robert Stock was designated for assignment. Righty Ryan Weber and left-hander Matt Hall were also outrighted to Triple-A Worcester.

Payamps, 26, had spent the previous two seasons with Arizona, appearing in a total of four games while allowing four runs (three earned) over seven total innings pitched in those appearances. He was designated for assignment last Friday.

The Dominican Republic native was originally signed by the Rockies as an international free agent in 2010 and has 145 career minor-league outings (119 starts) under his belt.

Per Statcast, Payamps utilizes a four-pitch mix that is comprised of a four-seam fastball, a slider, a sinker, and a changeup. He averaged 94.2 mph and topped out at 95.8 mph with his heater this past season.

With the addition of Payamps to the 40-man roster via a waiver claim, the Red Sox needed to create some room, and they did so by designating Stock.

The 31-year-old was initially claimed off waivers by Boston from the Phillies back on July 27.

In his debut season with the Sox, Stock posted a 4.73 ERA and 3.34 FIP over 10 appearances and 13 1/3 innings pitched spanning three separate stints with the big-league club.

Given the fact he can reach 99 mph with his heater, Stock may be someone that Boston would like to stash away in the minors for bullpen depth. The Washington native will of course have to clear waivers in order for that to happen, though.

As for Weber and Hall, the two hurlers who represented 40% of the Sox’ Opening Day rotation this year were outrighted to Triple-A after being designated for assignment on November 20.

Assuming both Weber and Hall accept their minor-league assignments as opposed to electing free agency, they too could provide integral swingman depth for the Red Sox since both are capable of starting and working out of the bullpen.

With Wednesday’s moves made, Boston’s 40-man roster is currently at full capacity. Expect more transactions like this one to be made by chief baseball officer Chaim Bloom and Co. as the offseason continues.

UPDATE: As pointed out by SoxProspects’ Chris Hatfield, Payamps is out of minor-league options, so the Red Sox could very well look to sneak him through waivers as they did with second baseman Christian Arroyo over the summer.
