BOSTON — Romy Gonzalez homered over the Green Monster on the first pitch faced by a Boston batter, Trevor Story added a two-run shot, and the Red Sox beat the Houston Astros 7-3 on Saturday.

Abraham Toro also had a two-run homer — one of three homers the Red Sox hit over Fenway Park’s fabled left-field wall — and Story hit an RBI double as Boston won its fourth straight.

Houston’s Christian Walker homered for the second straight day, a two-run shot off Walker Buehler in the first inning.

The benches and bullpens cleared when Astros reliever Héctor Neris yelled at the Red Sox dugout and third-base coach Kyle Hudson at the end of the seventh. But order was quickly restored.

After beating the AL West leaders on Roman Anthony’s walk-off single in the series opener Friday night, the Red Sox erased a quick 2-0 deficit when Story hit his drive in a three-run third against Colton Gordon (4-4), giving Boston a 4-2 lead.

Story’s shot hit the top of a billboard over the Monster seats and bounced out of Fenway after Rob Refsnyder’s RBI single.

Justin Wilson (3-1) came on in the fifth inning with runners on second and third and Boston leading 6-3. He struck out the only two batters he faced. Aroldis Chapman got the final two outs for his 20th save.

Gordon gave up six runs in four-plus innings.

Key moment

The Astros loaded the bases in the eighth against Jordan Hicks, but Carlos Correa struck out looking on a 99 mph fastball.
