OAKLAND, Calif. — All-Star Matt Chapman homered and had five RBI, leading the Oakland Athletics past the Seattle Mariners 9-2 on Tuesday night for their fifth straight win.
Matt Olson followed Chapman’s fifth-inning drive with a solo homer that extended his hitting streak to 11 games, marking the seventh time the A’s hit back-to-back homers this year.
The two slugging Matts provided Daniel Mengden (5-1) all the support he needed. Mengden allowed one run and four hits over seven impressive innings, striking out three and not walking a batter for the third straight start.
In the seventh, Marcus Semien got a double out of a miscue by the Mariners when first baseman Austin Nola tripped over right fielder Domingo Santana in shallow right.
Omar Narvaez hit two homers for the Mariners. Narvaez connected in the second before the A’s answered in the third with Chapman’s two-run single.
Chapman, who added a run-scoring double late, had six RBI on June 30 at the Angels.
Oakland has won seven of eight and 11 of 13, heating up as the second half begins just as the A’s did last season on the way to their first playoff berth in four years.
Mariners lefty Marco Gonzales (10-8), who had been 4-1 in his first seven outings and six starts against the A’s, was tagged for six runs and seven hits over six innings. He struck out five and walked one in Seattle’s fifth consecutive loss.
Oakland is 18-8 when facing a left-handed starter.
