Pinch-hitter Jake Smolinski hit a go-ahead, three-run homer during Oakland's five-run eighth inning that carried the Athletics to a 13-11 victory over the San Francisco Giants on Tuesday night. Khris Davis hit his 19th homer, and Stephen Vogt, Billy Butler and Josh Phegley each drove in two runs to help the A's finish a 5-1 trip that started with three wins in four games against the Angels. This was Oakland's most successful road trip of at least four games since also going 5-1 in September 2013.
