According to Ari Alexander of WHDH 7 News, the Boston Red Sox promoted right-handed pitcher Jack Anderson on April 14
Anderson was brought over to the Red Sox via the minor league portion of the Rule 5 Draft in December of 2024. That meant he was added to the organization, however, he didn’t need to be added to the 40-man roster at the time. Before he makes his major league debut against the Minnesota Twins, what should fans expect from the 26-year-old?
The righty spent most of his time (23 appearances, four starts) in Double-A in 2025. He looked great there in 75 1/3 innings, but struggled in his three starts (11 1/3 innings) in Triple-A.
2026 is a new year, though, and it started in the coolest way possible for Anderson. The 26-year-old made the roster for Great Britain in the World Baseball Classic. Obviously, the team didn’t do much, but it’s still an incredible experience for a young player.
Red Sox promote pitcher Jack Anderson to major league roster before April 14 Twins game
Anderson had a rough first outing with Worcester this season, but tossed six scoreless innings his second time around.
Anderson will likely be used as a reliever, but he can eat plenty of innings. Before joining the Red Sox organization, Anderson made one start in 118 appearances. He’s made nine starts in 28 appearances with the Red Sox. That makes it easier to imagine Boston using him in long relief outings.
Anderson does not have overpowering stuff. Over his first two games this season, he’s topped out his fastball at 93.1 MPH. Working out of the bullpen, maybe he’ll add an extra tick or two. If he struggles in the majors, not having a great fastball could be the main reason why.
The Florida State product throws his slider almost as much as his fastball. He mixes in a splitter a decent amount, with the rare curveball mixed in. Last season, he threw a cutter 15.9% of the time, but has yet to throw one in 2026.
Historically, Anderson limits walks but gives up some hits. While it’s just two starts (9 2/3 innings), he’s currently boasting a career-best .216 BAA. His 1.14 WHIP is second-best only to the 1.09 WHIP he posted in 2024.
Red Sox fans shouldn’t expect to see Anderson come in and throw the most dominant inning they’ve ever seen. However, he’s a smart pitcher who gained valuable experience this year. The righty will likely eat a handful of innings for them before being sent down again, waiting for his next shot. That outing can still impress, though, thanks to a strong slider and an ability to limit baserunners.
Anderson is an easy player to root for. Hopefully, he makes a good first impression.
