Arenado went 1-for-4 with a solo home run in Tuesday's 4-1 loss to the Reds.
Arenado's 400-foot blast off Hunter Greene in the seventh inning was the only offense the Cardinals could muster Tuesday. It was his first long ball since July 26, but he has gone 15-for-45 with eight RBI so far in August. On the season, the third baseman is hitting .270 with 12 homers, 53 RBI and 49 runs scored across 472 plate appearances.
