Red Sox pitching prospect Juan Valera opening 2025 season with High-A Greenville

Rising Red Sox pitching prospect Juan Valera will open the 2025 minor-league season with High-A Greenville, as was revealed when the Drive released their Opening Day roster earlier Wednesday.

It is an aggressive assignment for Valera, who turns 19 in May and is easily the youngest player on Greenville’s roster. Still, despite having limited experience above rookie ball, the Red Sox believe the right-hander is deserving of such a challenge after putting together an impressive spring in Fort Myers.

“He had a productive offseason coming into camp strong, physically and mentally,” Red Sox senior director of player development Brian Abraham said of Valera. “We saw a jump in velocity and an improvement in his secondaries with a willingness to challenge in the zone. He earned an opportunity to be challenged in Greenville.”

Valera, who originally signed with Boston for a modest $45,000 as an international free agent coming out of the Dominican Republic in April 2023, was not on many people’s radars at this time last year. The Sabana Grande de Palenque native was coming off a debut season in which he put up a 5.93 ERA (4.67 FIP) with 31 strikeouts to 20 walks over 15 appearances (27 1/3 innings) in the Dominican Summer League.

To open the 2024 campaign, though, Valera began to draw attention to himself thanks to what he was doing in the Florida Complex League. In 11 outings (nine starts) for the FCL Red Sox, the righty posted a 1.79 ERA (3.25 FIP) with 40 strikeouts to 14 walks over 40 1/3 innings in which opposing hitters batted .128 against him. He was then rewarded with a promotion to Low-A Salem on July 23 and closed out the season by pitching to a 2.35 ERA (3.54 FIP) with 28 strikeouts to 14 walks in seven starts (23 innings) for Boston’s Carolina League affiliate while holding opponents to a .120 batting average.

Altogether, Valera forged a 1.99 ERA (3.36 FIP) with 68 strikeouts to 28 walks in 18 appearances (16 starts) spanning 63 1/3 innings between the FCL and Salem. He led all Red Sox minor-leaguers who logged at least 60 innings last season in ERA, batting average against (.125), WHIP (0.85), line-drive rate (10.3 percent), and groundball rate (56.6 percent), per FanGraphs. To that end, he was recognized as a 2024 Florida Complex League All-Star and SoxProspects.com’s Pitcher of the Year.

Looking to build off the momentum he gained in his first season stateside, Valera came into camp this spring and wasted little time turning heads on the backfields. He was named to the Red Sox’ Spring Breakout roster last month and pitched against prospects from the Twins organizations in the first-ever “Futures at Fenway South” game at JetBlue Park on March 14. As part of that showcase, in which he struck out four and allowed two runs in three innings, Valera showed flashes of his potential.

Valera, as noted by SoxProspects.com’s director of scouting Ian Cundall, featured a 97-99 mph fastball that reached 100 mph “multiple times.” The 6-foot-3, 205-pound hurler also mixed in an 89-92 mph slider, an 86-88 mph sweeper, and a 91-94 mph changeup. If there were any drawbacks from the performance, it’s that Valera lost the strike zone a bit after his typical three-quarters arm slot got “out of sync.” Josh Norris echoed the same sentiment in a recent piece for Baseball America.

Lauded by club officials for his work ethic and openness to instruction, Valera is currently regarded by Baseball America as the No. 14 prospect in Boston’s farm system, which ranks sixth among pitchers in the organization. MLB Pipeline has him ranked 18th among its top 30 Red Sox prospects, while SoxProspects.com has him at No. 19 ahead of its next rankings update.

In Greenville, Valera is slated to join a talented pitching staff that includes the likes of Payton Tolle, Jedixson Paez, Hayden Mullins, and Jojo Ingrassia, among others. The 2025 season begins for the Drive on Friday night when they open a three-game weekend series against the Bowling Green Hot Rods at Fluor Field.

Why Juan Valera took the biggest leap of any Red Sox pitching prospect in 2024

The case can be made that Juan Valera took the biggest leap of any Red Sox pitching prospect in 2024.

Originally signed for $45,000 as an international free agent coming out of the Dominican Republic in April 2023, Valera posted a 5.93 ERA (4.67 FIP) over 27 1/3 innings as part of his professional debut in the Dominican Summer League last year. As such, the young right-hander came into the 2024 season with very little fanfare.

Transitioning from the Dominican Summer League to the Florida Complex League, Valera impressed out of the gate in his stateside debut. The 18-year-old forged a 1.79 ERA (3.25 FIP) with 40 strikeouts to 14 walks in 11 outings (nine starts) spanning 40 1/3 innings for the FCL Red Sox. He held opposing hitters to a .128 batting average and leveraged his performance into a promotion to Low-A Salem in late July.

The trade deadline passed shortly thereafter, but not before Valera saw three teammates (fellow teenage righties Gilberto Batista, Ovis Portes, and Yeferson Vargas) get moved elsewhere. The Red Sox, however, elected to hold onto Valera, who proceeded to post a 2.35 ERA (3.54 FIP) with 28 strikeouts to 14 walks in seven starts (23 innings) for Salem to close out the year. Opposing hitters in the Carolina League batted just .120 against him in that stretch.

Altogether, Valera pitched to a 1.99 ERA (3.36 FIP) with 68 strikeouts to 28 walks in 18 appearances (16 starts) spanning 63 1/3 innings between the FCL and Salem this past season. Among the 39 Red Sox minor-leaguers who threw at least 60 innings in 2024, Valera ranked first in ERA, batting average against (.125), WHIP (0.85), line-drive rate (10.3 percent), and groundball rate (56.6 percent), fifth in swinging-strike rate (15.9 percent), eighth in FIP, 12th in strikeout rate (27.9 percent), and 13th in xFIP (3.76), per FanGraphs.

As far as post-season accolades are concerned, Valera was recognized as a 2024 Florida Complex League All-Star by Minor League Baseball. He was also named a 2024 SoxProspects.com All-Star and the 2024 SoxProspects.com Pitcher of the Year.

Standing at 6-foot-3 and around 225 pounds, Valera throws from a high three-quarters arm slot and utilizes a side-step delivery. This past season, the projectable hurler operated with a four-pitch mix that consisted of a 93-96 mph fastball that reached 99 mph, an 85-88 mph slider that featured 10-to-4 break, an 82-85 mph sweeper, and an 89-92 mph changeup that is still viewed as a work progress.

Lauded by club officials for his strong work ethic and teachability, Valera is currently regarded by SoxProspects.com as the No. 19 prospect in Boston’s farm system, which ranks ninth among pitchers in the organization. MLB Pipeline has the righty ranked 20th on its top 30 Red Sox prospects list while Baseball America has him unranked, though that will likely change soon.

“We’re super high on this kid,” Red Sox director of pitching Justin Willard said of Valera when speaking with The Boston Globe’s Sarah Barber back in August. “He’s starting to get to some pretty cool shapes from a pitch-design standpoint. We’re very excited about this kid, and he’s only continued to go out there and kind of hammer the things that he needs to for his long-term development as well.”

Valera, who turns 19 in May, is projected by SoxProspects.com to return to Salem for the start of the 2025 minor-league season. He should, however, have the opportunity to advance to High-A Greenville before the end of the summer depending on how aggressive the Red Sox are willing to be.

Red Sox pitching prospect Juan Valera named Florida Complex League All-Star

Red Sox pitching prospect Juan Valera has been named a 2024 Florida Complex League All-Star, Minor League Baseball announced on Thursday.

Unlike fellow FCL All-Star Franklin Arias, Valera is not currently regarded by Baseball America or MLB Pipeline as one of the top 30 prospects in Boston’s farm system. SoxProspects.com slates him in at No. 27 on its list, which ranks 12th among pitchers in the organization.

Valera appeared in 11 games (nine starts) for the rookie-level FCL Red Sox this season. The 18-year-old right-hander posted a 1.79 ERA and 3.25 FIP with 40 strikeouts to 14 walks over 40 1/3 innings. Opposing hitters batted just .128 against him.

Among 26 FCL pitchers who threw at least 40 innings in 2024, Valera led in both batting average against and WHIP (0.77). He also ranked second in FIP and line-drive rate (8.8 percent), third in ERA and groundball rate (56 percent), sixth in walks per nine innings (3.12), walk rate (9.1 percent), and strikeout rate (26 percent), seventh in xFIP (3.94), ninth in swinging-strike rate (16 percent) and 13th in strikeouts per nine innings (8.93), per FanGraphs.

Like the aforementioned Arias, Valera was promoted from the FCL to Low-A Salem on July 23. He has since pitched to a 1.65 ERA (3.95 FIP) with 15 strikeouts to 12 walks through his first five starts (16 1/3 innings) for Boston’s Carolina League affiliate. While the walks are clearly up, he has held opponents to a .098 batting average thus far.

Valera, who turned 18 in May, originally signed with the Red Sox for $45,000 as an international free agent coming out of the Dominican Republic in April 2023. The Sabana Grande de Palenque native made his professional debut in the Dominican Summer League last June but has really emerged as one to watch this year.

“We’re super high on this kid,” Red Sox director of pitching Justin Willard told The Boston Globe’s Sarah Barber earlier this month. “He’s starting to get to some pretty cool shapes from a pitch-design standpoint. We’re very excited about this kid, and he’s only continued to go out there and kind of hammer the things that he needs to for his long-term development as well.”

Standing at a projectable 6-foot-3 and 225 pounds, Valera operates with a four-pitch mix that consists of a fastball that has sat between 94-99 mph this season, a slider, a sweeper, and a changeup. As noted in his SoxProspects.com scouting report, “he checks a lot of boxes that you look for in a pitching prospect his age.”

“This kid, he shows up every day and just gets his work done,” Salem pitching coach Juan Rivera said of Valera in a separate conversation with Barber last week. “If I don’t see him one time during the day, I know for a fact he still got his work in without me having to hover over him. He’s just a really autonomous player, understands his routines and what he needs to accomplish, and just crushes it.”

Red Sox to promote prospects Franklin Arias, Juan Valera to Low-A Salem

The Red Sox are promoting infield prospect Franklin Arias and pitching prospect Juan Valera from the Florida Complex League to Low-A Salem, according to reports from The Boston Globe’s Alex Speier and SoxProspects.com.

Arias, 18, is currently ranked by Baseball America as the No. 9 prospect in Boston’s farm system. The right-handed hitter batted .355/.471/.584 with 16 doubles, two triples, six home runs, 28 RBIs, 41 runs scored, 30 stolen bases, 34 walks, and 34 strikeouts in 51 games (206 plate appearances) for the rookie-level FCL Red Sox this season.

In the month of July alone, Arias has slashed a ridiculous .482/.574/.768 with five doubles, one triple, three homers, nine RBIs, 18 runs scored, 14 stolen bases, 12 walks, and 14 strikeouts over 18 games (68 plate appearances). Among 70 qualified FCL hitters coming into play on Monday, Arias led the pack in batting average, on-base percentage, OPS (1.055), and wRC+ (180). He also ranked second in slugging percentage, fifth in isolated power (.229), 17th in walk rate (16.5 percent), and 23rd in strikeout rate (17.5 percent), per FanGraphs.

Defensively, Arias has split his playing time on the field this season between shortstop and second base. The 5-foot-11, 170-pounder committed nine errors in 33 starts at short for the FCL Red Sox but did not commit an error in 10 starts at second. He also made four starts at DH.

Arias, who turns 19 in November, originally signed with the Red Sox for $525,000 as a highly-touted international free agent coming out of Venezuela in January 2023. The Caracas native made his professional debut in the Dominican Summer League last year and has since added to his glove-first profile by showing signs of immense improvement at the plate.

“He’s one of these guys that you can close your eyes and you know he’s going to field a ground ball,” Red Sox director of player development Brian Abraham said of Arias when speaking with Speier earlier this month. “He’s a very easy plus defender, which is, I think, what’s really exciting about him. The bat has always been behind, and now the bat is starting to creep up and all of a sudden, you’re looking at a player who does a little bit of everything.”

Valera, meanwhile, is not yet ranked by Baseball America but is rated by SoxProspects.com as the No. 42 prospect in Boston’s farm system. The 18-year-old right-hander posted a 1.79 ERA and 3.29 FIP with 40 strikeouts to 14 walks in 11 appearances (nine starts) spanning 40 1/3 innings for the FCL Red Sox this season. Opposing hitters batted just .128 against him.

Dating back to the beginning of June, Valera has pitched to a 0.98 ERA (2.20 FIP) with 29 strikeouts to four walks over his last seven starts (27 2/3 innings). That includes punching out a season-high seven batters in five perfect frames against the FCL Braves last Thursday.

Among the 20 FCL pitchers who entered Monday with at least 40 innings under their belt to this point in the year, Valera ranked first in batting average against and WHIP (0.77), second in FIP, third in groundball rate (56 percent), fourth in ERA fifth in strikeout rate (26 percent), sixth in walk rate (9.1 percent) and xFIP (3.98), and eighth in swinging-strike rate (16 percent), per FanGraphs.

Valera, who turned 18 in May, originally signed with the Red Sox for $45,000 as an international free agent coming out of the Dominican Republic in April 2023. The Sabana Grande de Palenque native appeared in 15 games (one start) as part of his professional debut in the Dominican Summer League last season but has really burst onto the scene this year.

Listed at 6-foot-3 and 205 pounds, Valera primarily operates with a 93-97 mph fastball and an 83-85 mph slider, according to his initial SoxProspects.com scouting report. The projectable righty does not yet feature a third pitch and is inconsistent when it comes to throwing strikes. Still, “he checks a lot of boxes that you look for in a pitching prospect his age.”

While Arias and Valera are getting somewhat of a head start in making the jump to Salem, others in Fort Myers will likely join them at some point in August since the 2024 FCL season will conclude on July 30 at the latest.
