Arenado went 1-for-3 with a solo home run, a walk and three total runs scored in Saturday's 11-5 loss to the Reds.
Arenado is up to 21 homers this season, including seven over 17 games in August. He's hitting .254 (16-for-63) with 15 RBI this month. The third baseman is batting .243 with a .768 OPS through 121 contests. Arenado battled an intercostal injury earlier in the week, but he looks set to play through it with little impact on his performance -- he's hit safely in three straight games since he returned from missing two contests due to the injury.
