San Diego: Jed Lowrie hit a two-run homer with two outs in the top of the 10th inning after Oakland tied the game on a two-out homer in the ninth Tuesday to give the A’s a 4-2 victory over the San Diego Padres in the opener of a short, two-game series at Petco Park. Marcus Semien singled with one out in the 10th and was at third on a stolen base and a throwing error by catcher Raffy Lopez when Lowrie connected on a 374-foot drive to right off Padres right-handed reliever Adam Cimber (3-3). Right-hander Lou Trivino (4-1) struck out two in two perfect innings to earn the win as A’s relievers retired 10 of the final 11 Padres batters to end the game. Right-hander Blake Treinen got his 16th save.
