BALTIMORE (AP) — 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 road trip that began against the New York Yankees. The Red Sox lead the Yankees by a game for the AL’s top wild card.

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 Detroit’s Tarik Skubal.

Jackson homered to lead off the third. Jeremiah Jackson hit an RBI double to tie it at 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.

Refsnyder, activated before the game, gave the Sox lineup a boost from the right side.

“We needed it,” manager Alex Cora said. “We struggled against lefties lately. I think the quality of the pitchers is one of the reasons and not having him is the other one. He’s just a good at-bat against them. He puts them in a spot where they have to make decisions later in the game or early in the game. Bring in a righty and then we can maximize the bench and use them accordingly.”

Key moment

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

Key stat

Boston swept a four-game series from Baltimore for the first time since Aug. 10-13, 2018.

Lowe on Paternity List

The Boston Red Sox placed first baseman Nathaniel Lowe on the paternity list Thursday and activated outfielder Rob Refsnyder from the 10-day injured list.

Lowe, who signed with the Red Sox Aug. 18 after being released by Washington two days earlier, is hitting .296 with a homer and seven RBIs in nine games since joining Boston and immediately becoming its everyday first baseman.

The Red Sox also activated right-hander Justin Slaten from the 60-day injured list and optioned lefty Jovani Morán to Triple-A Worcester. Slaten was 1-4 with a 3.47 ERA in 24 games but has not pitched for Boston since May 28 because of shoulder inflammation.

Morán has a 6.75 ERA in two appearances this season but did not pitch in two games after the Red Sox called him up Tuesday.
