Spencer Arrighetti allowed two hits over six shutout innings to help the Houston Astros beat the Seattle Mariners 4-0 on Thursday and avoid a four-game series sweep.

Alex Bregman hit a two-run homer in the fourth against Mariners starter Logan Gilbert (3-3). Kyle Tucker led off the inning with a single and Bregman put Houston up by a pair of runs with the shot that barely cleared the left-field wall.

Bregman added a triple in the sixth inning that just escaped the grasp of a leaping Julio Rodríguez in center field, and scored on a groundball to second base from Victor Caratini to give Houston a four-run lead.

Caratini also hit a solo homer in the fifth against Gilbert, who allowed four earned runs and eight hits over six innings of work.

While the Astros found success against Gilbert, the Mariners offense couldn’t do much against Arrighetti (3-5), who allowed just a pair of singles while walking three and striking out a career-high eight Seattle hitters.

Mariners shortstop J.P. Crawford had a highlight-reel play in the seventh when he dove for a groundball off the bat of Mauricio Dubón and flipped it with his glove to second baseman Dylan Moore, who threw to first for the out.

Rafael Montero, Ryan Pressly, and Josh Hader each pitched one scoreless inning in relief for the Astros.
