Didi Gregorius stepped to the plate in the third inning and guessed fastball. Next thing the rookie knew, he was circling the bases after the first pitch he saw as a member of the Arizona Diamondbacks. Gregorius lined a ball into the right-field seats that was picked up by Zack Hample, a 35-year-old New Yorker. Hample also caught Francisco Cervelli's tying home run into the left-field stands off J.J. Putz in the ninth, but the Diamondbacks bounced back to beat the Yankees 6-2 when Cody Ross hit a go-ahead single in the 12th and Eric Chavez followed with a three-run double against his former team.
