Adam Eaton smacked the first walkoff home run of his career Monday against the Orioles. Eaton led off the bottom of the ninth inning after Brad Ziegler's blown save evened the score 6-6. The rookie outfielder jacked Darren O'Day's first pitch over the stands in right center to improve Arizona's record to 60-57. Eaton, currently riding a five-game hitting streak, is batting .360 in August, though he entered the month with a .192 batting average.
