Red Sox promote Rule 5 addition Jack Anderson to Triple-A Worcester

The Red Sox promoted right-hander Jack Anderson from Double-A Portland to Triple-A Worcester on Friday, as was first reported by Beyond the Monster’s Andrew Parker.

Anderson opened his first season in the Red Sox organization with Portland as a member of the Sea Dogs’ bullpen. The 25-year-old appeared in two games for Boston’s Eastern League affiliate out of the gate, allowing one unearned run on four hits, zero walks, and 10 strikeouts over 4 2/3 innings of relief.

A former 16th-round draft pick of the Tigers coming out of Florida State in 2021, Anderson switched organizations for the first time in his professional career over the winter when the Red Sox plucked him in the minor-league phase of December’s Rule 5 Draft.

Anderson appeared in three Grapefruit League games for Boston as a minor-league call-up this spring, yielding two earned runs on seven hits, one walk, and five strikeouts over 3 1/3 innings. He also retired the lone batter he faced (former Red Sox farmhand Esteban Quiroz) in the club’s exhibition finale against the Sultanes de Monterrey in Mexico on March 25.

In that particular outing, which only required five pitches (four strikes), Anderson threw three four-seam fastballs, one cutter, and one slider, per Baseball Savant. Throwing from a three-quarters arm slot, the 6-foot-3, 197-pound righty reached 91.6 mph with his heater, 84.6 mph with his cutter, and 80.1 mph with his slider.

Anderson, who does not turn 26 until November, has previous experience at the Triple-A level. The Florida native appeared in eight games (made one start) for Detroit’s top affiliate last season and posted a 5.82 ERA (4.98 FIP) with 10 strikeouts to six walks over 17 innings with the Toledo Mud Hens.

With the WooSox, Anderson seems likely to join a righty-heavy bullpen mix that consists of Luis Guerrero (on the 40-man roster), Bryan Mata, Nick Burdi, Isaiah Campbell, Jose Adames, Wyatt Mills, Jacob Webb, and lefty Brendan Cellucci. Hobie Harris, who was also taken in the minor-league phase of December’s Rule 5 Draft, is currently on Worcester’s 7-day injured list with right shoulder inflammation.
