Even on days when the offense gets out to a slow start, it never feels like the A’s are out of a game in the late innings with their firepower up and down the lineup. As catcher Sean Murphy demonstrated on Sunday, all it takes is one swing.

An A’s offense that was stymied by Tigers left-hander Matthew Boyd for most of the day was finally jump-started by Murphy’s explosion at the plate. His game-tying solo shot off Boyd in the eighth — Murphy’s first of the year — ignited a late rally for the A’s, which was finished off in the ninth by Mitch Moreland. The veteran reached base on an error to bring home Matt Olson for a walk-off 3-2 victory.

The win capped off a four-game sweep of Detroit and extended Oakland’s American League-best winning streak to eight games.
