The loss ended Seattle's eight-game home win streak and spoiled a solid outing from lefty Ariel Miranda, who allowed four hits and three runs over 5 2/3 innings in his third start since being acquired for Wade Miley. Seth Smith and Robinson Cano each drove in a pair of runs for Seattle.
The Mariners (66-57) missed a chance to narrow the gap on front-running Texas, which retained its six-game lead in the AL West.
