OAKLAND, Calif. — Tanner Roark has been in Oakland long enough already to understand this winning vibe.

Roark is doing his part to keep the Athletics on a roll as the September stretch run approaches, striking out seven without walking a batter over six-plus innings in a 5-3 victory over the Yankees on Thursday night for a three-game series sweep.

“It shows what these guys in here in the clubhouse and all the coaches are all about,” Roark said. “We’re fighters and we’re not going to give in, we’re going to have fun, we’re going to do the small things great, get runs across the board and try to do our best to put up zeros.”

Mark Canha hit a two-run single as the A’s immediately jumped on Yankees starter Masahiro Tanaka (9-7) on the way to a seventh victory in eight overall.
