Arenado went 2-for-4 with a three-run home run in a loss to Atlanta on Wednesday.
The veteran third baseman helped St. Louis get off to a fast start, slugging a three-run shot to left field in the first inning. That was nearly all the offense the Cardinals mustered in the contest, however, as they ended up losing 7-4. Arenado leads St. Louis with 21 homers and 65 RBI on the season, though his .264 average is well below his career .290 mark.
