Red Sox promote Jack Anderson from Worcester

The Boston Red Sox have promoted a right-handed pitcher from Triple-A Worcester.

MassLive’s Sean McAdam confirmed a report from 7News’ Ari Alexander Tuesday morning that Jack Anderson was called up to join the Red Sox. The corresponding move is lefty Tyler Samaniego being optioned to Triple-A, according to a source. Anderson is en route to Minnesota ahead of Tuesday’s 7:40 p.m. ET first pitch.

If Anderson makes it into a game, it will mark his MLB debut. The Red Sox needed an arm after using three relievers (Jovani Morán, Samaniego and Ryan Watson) for more than two innings Monday in relief of ace Garrett Crochet, who was tagged for 11 runs (10 earned) while only recording five outs in the worst start of his career.

Anderson, who started Thursday’s game for Worcester and pitched six innings, will be able to give Alex Cora’s bullpen some length, if needed. The 26-year-old was drafted by the Tigers in 2021 and spent his time in the Detroit farm system as a reliever. Boston acquired Anderson during the minor league portion of the 2024 Rule 5 draft and he spent last season as both a reliever and starter.

During the 2025 season, Anderson had four starts and 19 relief appearances for Double-A Portland before making three starts with the WooSox.

Anderson has gone 1-0 in two starts with a 3.72 ERA and a 1.14 WHIP for the WooSox this spring. He struck out nine batters in 9.2 innings on the mound after not being an invite to major league spring training. He appeared in the World Baseball Classic as a member of Team Great Britain.

SoxProspects does not have Anderson ranked among the top 60 prospects in Boston’s system.

Two injured players (Triston Casas and Johan Oviedo) are candidates to be placed on the 60-day IL to clear a spot for Anderson, who is not on the 40-man roster.
