Strike three, in part because Contreras didn't frame it very well. The batter ended up hitting an RBI single and Lackey started yelling at the ump as the play was still happening. After the play Contreras kept arguing, was tossed, and then spiked his facemask in the dirt.
It was pretty fun to watch the cubs lose their starting battery, but the ump acted like a chump. He tossed lackey with essentially a finger wave, like you'd give a child.
