OAKLAND, Calif. — Mike Fiers won in his first start at the Coliseum since pitching a no-hitter earlier this month and the Oakland Athletics beat Seattle 6-5 Saturday, sending the Mariners to their fifth straight loss.
Matt Chapman homered and Ramon Laureano doubled in his fifth straight game, matching Miguel Tejada for the Oakland record.
Domingo Santana hit two home runs and Mitch Haniger also connected for Seattle, which has lost eight of nine.
Mariners third baseman Kyle Seager doubled and singled in his season debut after recovering from surgery to repair a tendon in his left hand that he hurt diving for a ball during spring training.
Fiers (4-3) received a warm welcome when introduced before the game, his first at home since throwing a no-hitter against Cincinnati on May 7. He went six innings against Seattle, allowing three runs and five hits.
Blake Treinen gave up Santana’s home run in the ninth before finishing for his 10th save in 12 tries.
Yusei Kikuchi (3-2) faced Oakland for the third time in as many different ballparks this season. The Japanese lefty previously pitched against the A’s in Tokyo and Seattle, taking a no-decision each time. He was done after 3 1/3 innings, giving up five runs and 10 hits.
