Plate umpire Chris Conroy issued warnings to both teams after Braves pitcher Eric O'Flaherty plunked David DeJesus in the seventh inning, after Jeff Samardzija hit Jason Heyward in the back in the top of the inning.

Atlanta manager Fredi Gonzalez argued, and was ejected by Conroy.

The Cubs insisted they weren't throwing at Heyward with a 2-1 lead and one out. Heyward homered off Samardzija in the second.
