BALTIMORE — Romy Gonzalez hit a go-ahead single in the eighth inning, Rob Refsnyder homered in his return from a strained left oblique, and the Boston Red Sox earned a 3-2 victory over the Baltimore Orioles to complete a four-game sweep Thursday.

Trevor Story also homered for Boston, which went 7-1 on a two-city trip that began against the New York Yankees. The Red Sox lead the Yankees by a game for the AL’s top wild card, with New York playing Thursday night at the Chicago White Sox.

Alex Jackson went deep for Baltimore, which went 1-7 on its homestand against Houston and Boston. The last-place Orioles are a season-high 18 games out of first in the AL East.

Roman Anthony drew a leadoff walk in the eighth against Rico Garcia (0-1), moved to second on Story’s one-out grounder and scored when Gonzalez ripped a single to left.

Jordan Hicks (2-7) pitched a scoreless seventh. Steven Matz worked the ninth for his second save.

Garrett Crochet surrendered two runs in six innings for Boston. He struck out seven to raise his season total to a majors-best 214, two more than Tarik Skubal of Detroit.

Jackson homered to lead off the third. Jeremiah Jackson hit an RBI double to make it 2-2 in the fifth, but Crochet struck out Gunnar Henderson and got Ryan Mountcastle to line into a double play to strand two in scoring position.

Baltimore starter Cade Povich gave up solo home runs to Story in the first inning and Refsnyder in the fourth. He allowed two runs in five innings and struck out five.

Garrett Whitlock of Boston struck out pinch-hitter Dylan Beavers with two runners on to end the eighth.
