Twins Claim Jack Anderson Off Waivers From Red Sox

Anderson has pitched 8.0 IP with a 3.38 ERA and 0.372 xwOBA in three relief appearances for Boston—minimal upside for a MIN bullpen already allowing 480 runs (third-worst in AL Central).

Anderson's departure (3.38 ERA, 0.372 xwOBA in 8 IP) removes minimal rotation depth; Sandoval's return timeline unclear with no 2026 stats available, so Boston relies on Gray (2.61 ERA, 10-1) and Suarez (3.15 ERA) as its anchors.

Boston (9-13, -13 run differential) shuffles bullpen depth as the rotation remains anchored by Suarez (3.22 ERA, 1.07 WHIP). Anderson was optioned despite a 3.00 ERA in limited action, suggesting Rivera offers more immediate relief value against a Yankees lineup arriving tonight.

Anderson enters a rotation where Crochet (0.29 ERA), Gray (0.21 ERA), and Suarez (0.29 ERA) have combined for a 5-2 record through early season. Boston sits 6-10 with a -7 run differential and will need to clear a 40-man spot before the promotion becomes official.
