Chris Davis hit a grand slam in the 10th inning, his second slam in 12 days, and the Baltimore Orioles beat the host Oakland Athletics, 7-3, on Wednesday after overcoming a two-run deficit in the sixth.
The grand slam, which came on a 3-2 pitch from Arnold Leon (0-1), was the 28th home run of the season for Davis and his third in four games. It came two batters after Gerardo Parra was intentionally walked to load the bases; Caleb Joseph and Manny Machado had led off the inning with back-to-back singles.
Closer Zach Britton (2-0) pitched a season-high two and a third scoreless innings for the win.
