Heredia’s RBI double lifts Mariners over A’s in 10

Jean Segura scored the winning run from first base on Guillermo Heredia’s one-out double into the right-center-field gap in the 10th inning, as the Mariners topped the A’s, 3-2, in Tuesday night’s series opener. Oakland starter Trevor Cahill tossed seven strong innings, but Seattle’s Mike Zunino hit a game-tying two-run homer in the seventh.
