Lonnie Chisenhall led off the ninth with a base hit against A's closer Edward Mujica, who struck out Giovanny Urshela before falling behind Bourn, 2-0, and serving up a ground-rule double to right-center field, making a winner out of Danny Salazar. The right-hander held the A's to just one hit -- an Eric Sogard single in the third -- over eight innings.
A's righty Kendall Graveman, who had a 10.22 ERA over his last three starts, returned to form with 6 2/3 strong innings, allowing one unearned run and five hits.
