Holliday collected three hits and hit the go-ahead home run in the eighth inning against the Braves on April 7, giving the Rockies a 2–1 win. In a three-game sweep of Atlanta, he hit .462 (6-for-13), with a double, triple and home run, and six RBI. He earned the NL Player of the Week award for the period ending April 13 as the Rockies won four of six. Holliday led the NL with a .480 batting average and 10 RBI, while homering twice with an .880 slugging percentage and .519 on-base percentage. He hit the game-tying home run against New York Mets closer Billy Wagner in the bottom of the ninth inning on May 23, then the game-winning single off Aaron Heilman in the bottom of the 13th to drive in Jonathan Herrera. Two days later, the Rockies placed Holliday on the 15-day DL due to a strained left hamstring, and reactivated him on June 10.
