Overview
- Eduardo Rivera, promoted earlier Tuesday to Triple-A, was called up to the Red Sox late Tuesday night, MassLive’s Chris Cotillo reported.
- Boston optioned right-hander Jack Anderson to Triple-A to open an active roster spot, and it still must clear a 40-man place that could come via a 60-day injured list move.
- The call-up follows injuries that have stretched the staff, including Sonny Gray going on the injured list and several depth starters sidelined or inactive.
- Rivera, a 6-foot-7 lefty who can touch 98 mph and was released by Oakland in 2024 before signing with Boston, has not pitched above Double-A and opened 2026 with a 0.90 ERA and 16 strikeouts in 10 innings.
- His role has not been set, though local reporting points to bullpen work against the Yankees this week.
