BALTIMORE — Zach Eflin pitched six impressive innings to improve to 4-0 since joining the Orioles, and Gunnar Henderson and Cedric Mullins homered in Baltimore’s 5-1 victory over the Boston Red Sox on Thursday night.
Eflin (9-7) has won all four starts since Baltimore acquired him from Tampa Bay before the trade deadline. He allowed a run and five hits, striking out a season-high eight without a walk.
The Orioles pulled into a first-place tie with the idle New York Yankees atop the AL East. Boston is eight games behind.
Nick Pivetta (5-8) allowed three runs and three hits in five innings. He struck out six and walked one, but two of the hits he yielded were homers.
Henderson went deep for the second straight game and 31st time in 2024. His two-run shot in the fourth gave the Orioles a 2-1 lead. Mullins hit a solo homer in the fifth.
Wilyer Abreu homered in the fourth for Boston’s lone run.
Ryan Mountcastle delivered a pinch-hit single in the sixth to drive in a run and make it 4-1.
Gregory Soto allowed two of his three batters to reach in the seventh in relief of Eflin, but Burch Smith came on and escaped the jam with a double play grounder.
Colton Cowser hit an RBI double in the seventh.
Boston reliever Chase Shugart made his big league debut, allowing a run and three hits in 2 2/3 innings.
Although the Orioles and Yankees have come back to earth of late, Boston has a lot of ground to make up in the standings. The Red Sox have dropped six of eight and trail Kansas City by 2 1/2 games for the American League’s final wild card.
Baltimore is 6-1 against the Red Sox this year and 27-13 vs. the AL East.
