CHICAGO — Josh Rojas, Dylan Moore and Victor Robles hit consecutive homers in Seattle's eight-run first inning and the Mariners beat the Chicago White Sox 10-0 on Friday night to end a three-game slide.
George Kirby pitched seven strong innings and Jorge Polanco added a two-run drive in the fourth as Seattle won for just the second time in 10 games and handed the major-league worst White Sox their 12th straight loss. Chicago was also shut out for the 13th time this season.
The Mariners remained one game behind first-place Houston in the AL West after once having a 10-game lead in the division.
Seattle hadn't gone deep back-to-back this season until they teed off against Chicago rookie Drew Thorpe, scoring all eight runs against the right-hander with two outs. The Mariners last hit three straight homers on June 21, 2022, at Oakland.
''A great game for our offense tonight,'' Seattle manager Scott Servais said. ''We had been struggling in the worst way. I'm really happy for our guys to jump out like we did today.''
The Mariners entered having scored two runs or fewer in seven of their previous eight games, but didn't wait for the arrival of All-Star outfielder Randy Arozarena to kick-start their offense. Arozarena was added via trade from Tampa Bay late on Thursday and reliever Yimi García was acquired from Toronto on Friday. Both are expected to join the Mariners on Saturday.
''We have to keep it going, certainly with all the action today, all the transactions,'' Servais said. ''You know it does spark some things once and a while in guys and hopefully it continues tomorrow when these players show up.''
Kirby (8-7) allowed six hits, struck out seven and walked one in coasting to his first win in a month despite nine straight quality starts. The right-hander had all the runs he needed before he took the mound.
