Arenado was ejected from Wednesday's game against the Cubs for arguing a called check-swing strike three, John Denton of MLB.com reports.
Arenado was called out on a check swing by the home plate umpire to end the third inning, and the third baseman will head to the clubhouse early after disputing the call. The 31-year-old finished the contest 0-for-2 and should be back in the lineup for Thursday's series finale in Chicago.
