BOSTON — Pete Alonso hit a two-run homer and Shane Baz pitched seven solid innings as the Baltimore Orioles beat the Boston Red Sox 4-2 on Tuesday night.

Coby Mayo also homered for Baltimore, which won its third straight and ended a three-game road skid.

Baz (3-5) pitched seven innings for a second straight start, allowing four hits and striking out six as he picked up consecutive wins for the first time this season. After giving up a leadoff triple to Jarren Duran in the first, Baz held Boston without another hit until the fifth and had a stretch of retiring 10 straight batters.

Rico Garcia struck out two in the ninth for his fourth save.

Alonso’s third-inning homer was his 12th of the season. He belted a 2-2 pitch from Connelly Early (5-3) well over the Green Monster in left field to put Baltimore up 3-1 and give the slugging first baseman 38 RBI.

Gunnar Henderson’s double to left in the first inning extended his streak of reaching base safely at Fenway Park to 23 games — as many times as he has appeared at the ballpark.

Mayo tied it at 1-all in the second with his seventh homer of the season, a drive to the top of the Monster that was initially called a double before getting overturned on a video review.

Wilyer Abreu and Marcelo Mayer drove in Boston’s runs on sacrifice flies as the Red Sox fell to 9-20 at home.

Early went 5 1/3 innings, allowing four runs on six hits.
