Overview
- The Red Sox beat the Seattle Mariners 9-8 in 10 innings on Tuesday when Trevor Story delivered a walk‑off single after he and Roman Anthony were activated from the injured list.
- Boston placed Willson Contreras on the 10‑day IL with a strained left hamstring and pushed Sonny Gray’s start back to give the veteran a planned break as the club protects long‑term availability.
- The Yankees began a West Coast trip with Aaron Judge traveling with the team and then opened the series at Angel Stadium with a 10-1 loss, extending recent swings in their offense.
- Roster activity on Sept. 1 included the Orioles claiming outfielder Luis Robert Jr. off waivers and the Mets activating Mark Vientos, who homered in his return, while teams used September roster expansion to promote depth.
- Across the league clubs are balancing late‑season urgency with workload management as the Cubs ride a record August power surge, the Dodgers’ offense cools, and rotations and bullpens are adjusted to protect pitchers for the stretch run.
