Cooper blooped a single to right field on a 2-2 pitch from Yankees starter Ivan Nova for his first hit in eight at-bats this season. He recorded the first RBI of his career on Saturday afternoon with a sacrifice fly to left.
"It was great," said Cooper, who finished the afternoon 2-for-3 with a walk. "Something I obviously wanted to do, to get the monkey off the back, so to speak, and get it over with so you can get to playing the game again.
"This is kind of the Mecca of baseball. So not only being here, but being able to get my first hit here, is something I'll never forget."
The 24-year-old Cooper was promoted to the Major Leagues on Friday. He was hitting .395 with two home runs and 19 RBIs in 20 games this season for Triple-A Las Vegas.
