Red Sox promote pitching prospect Jay Groome to Triple-A Worcester

Groome, who turns 24 next month, is currently regarded by Baseball America as the No. 13 prospect in Boston’s farm system, ranking sixth among pitchers in the organization.

In 16 appearances (14 starts) for the Sea Dogs this season, the 23-year-old left-hander posted a 3.52 ERA and 4.92 FIP to go along with 81 strikeouts to 38 walks over 76 2/3 innings of work.

Among qualified Eastern League pitchers, Groome ranks 11th in strikeout rate (24.9%), fourth in batting average against (.206), and fifth in ERA, per FanGraphs.

Originally selected by Boston with the 12th overall pick in the 2016 amateur draft out of Barnegat High School in New Jersey, Groome has endured plenty of ups-and-downs throughout his professional career. His first full season in pro ball was mired by arm injuries, ultimately resulting in him undergoing Tommy John surgery in May 2018.

Upon returning from Tommy John, Groome made a handful of rehab starts to close out the 2019 campaign. Then in 2020, the COVID-19 pandemic wiped out the minor-league season altogether. Limited to working out at the Sox’ alternate training site in Pawtucket, Groome was later added to the club’s 40-man roster that November in order to receive protection from the Rule 5 Draft.

After splitting 2021 between High-A Greenville and Portland, Groome returned to the Sea Dogs’ starting rotation for the start of the 2022 season and now finds himself on the cusp of the major-leagues.

Listed at 6-foot-6 and 257 pounds, Groome throws from a three-quarters arm slot and operates with a four-pitch mix that consists of a low-90s four-seam fastball that has topped out at 95 mph, a 76-80 mph curveball, a 79-82 mph changeup, and an 85-87 mph slider, according to his SoxProspects.com scouting report.

Groome, who will wear the No. 77 with the WooSox, becomes the latest Red Sox starting pitching prospect to make the jump from Portland to Worcester this year. The lefty joins fellow southpaws Brandon Walter and Chris Murphy as well as right-hander Brayan Bello.
