Carroll went 2-for-4 with a walk, two home runs, three runs scored and three RBI in Wednesday's 9-4 win over the Rockies.
The 24-year-old took advantage of his final game of the year at Coors Field, launching a solo shot in the first inning and a two-run homer in the second, both off Austin Gomber. The long balls were Carroll's first of September, but he's mostly put his early-season struggles behind him -- over 43 games since the beginning of August, he's batting .282 with 13 home runs, nine steals, 31 RBI and 46 runs.
