Red Sox Recall LHP Eduardo Rivera from Triple-A Worcester

BOSTON, MA—The Boston Red Sox today recalled left-handed pitcher Eduardo Rivera from Triple-A Worcester. To make room, Boston optioned infielder Brett Harris to Triple-A Worcester after last night’s game against the New York Mets.

Rivera, 23, will start today against the Mets. The left-hander has gone 7-2 with a 2.44 ERA (13 ER/48.0 IP), 1.15 WHIP, .185 opponent average (31-for-168) and 62 strikeouts in 22 games (four starts) this season between Triple-A Worcester (20 games, two starts) and Double-A Portland (two starts). He has pitched in one game for Boston this year, making his Major League debut on April 22 against the New York Yankees and allowing one hit in 3.1 scoreless innings with three strikeouts. Originally selected by the Athletics in the 11th round of the 2021 First-Year Player Draft, the Puerto Rico native was signed by the Red Sox as a minor league free agent in June 2024 and owns a 3.57 ERA (103 ER/260.0 IP) with 317 strikeouts in 85 career minor league games (42 starts).

Harris, 28, started at first base on Thursday against the Chicago White Sox, after being acquired in a trade with the Athletics on July 1. The right-handed hitter has also played in five Major League games this year for the Athletics, making one start at third base. He has also hit .317 (53-for-167) with 35 runs scored, 13 doubles, one triple, six home runs, 40 RBI, 25 walks, and a .936 OPS in 42 Triple-A games between Las Vegas (37 games) and Worcester (five). Originally selected by the Athletics in the seventh round of the 2021 First-Year Player Draft, the Illinois native has batted .192 (35-for-182) with three home runs and 17 RBI in 74 career Major League games with the Athletics (2024-26) and Red Sox (2026).
