BOSTON (Reuters) — The Boston Red Sox are calling up hard-throwing left-hander Eduardo Rivera from Triple-A Worcester to start Saturday’s game against the New York Mets, bypassing presumed starter Brayan Bello.
The move, first reported by MassLive and confirmed by an MLB press release, signals a tactical shift. Rivera, not Bello, is the weapon of choice against a Mets lineup that crushes right-handed pitching.
Rivera, 24, has dominated at Worcester. His fastball touches 100 mph. He pairs it with a high-spin slider. His Triple-A ERA is below 3.00, with a strikeout rate exceeding 11 per nine innings. His ground-ball tendency is a natural fit for Fenway Park’s dimensions.
Bello, the regular starter, has struggled. Over his last five outings, his ERA sits above 4.50. Manager Alex Cora, quoted in the MLB release, cited “matchup advantages.” This is a rest, not a demotion.
The Mets’ lineup is righty-heavy. Rivera’s left-handed delivery creates mismatches. Francisco Lindor and Pete Alonso are vulnerable to high-spin breaking balls from the left side. Yahoo Sports noted Rivera’s composure in high-leverage situations during Worcester’s playoff run.
| Pitcher | 2026 Triple-A ERA | K/9 | BB/9 | Fastball Velocity |
|---|---|---|---|---|
| Eduardo Rivera | 2.81 | 11.4 | 2.9 | 98-100 mph |
| Brayan Bello (last 5 MLB starts) | 4.72 | 7.8 | 3.5 | 94-96 mph |
Fan reactions are mixed. MassLive reported some hail the daring call-up. Others question the timing against a divisional rival. Cora emphasized “trust in the scouting report” in the official press release.
Saturday’s game is a classic lefty-righty duel. The Mets are expected to start a right-hander. Cool weather at Fenway could amplify Rivera’s sinking fastball. The key matchup: Rivera vs. Mets left-handed bats Jeff McNeil and Brandon Nimmo.
The start is an audition. A strong outing against a playoff contender could cement a permanent rotation spot. Bello may transition to a bullpen role or return as a stretched-out starter later this season.
