Kendall Graveman surrendered three earned runs on six hits in 5 2/3 innings for the A's, while Wei-Yin Chen yielded three earned runs on four hits in five innings for the O's. The teams traded scoreless innings from the seventh through ninth until Davis' mammoth shot to left-center.
MOMENTS THAT MATTERED
Victory slam: The Orioles' first baseman hit his second grand slam in 12 days, again breaking a tie and putting Baltimore up big. Davis, who has been red hot of late, has 28 homers and 79 RBIs on the season.
