Arenado went 3-for-3 with two walks and a three-run home run in Saturday's 6-5 extra-inning loss to the White Sox.
The veteran third baseman took Erick Fedde deep in the fifth inning to give the Cardinals a 5-3 lead, but it didn't hold up. Arenado has recorded multiple hits in three of the last five games, and the surge has boosted his slash line on the season to .296/.362/.408 with two homers, 14 runs and 19 RBI through 33 contests.
