They don't think so. But here's what happened yesterday,
The dugout incident occurred in the bottom of the seventh inning of the Brewers' 12-4 loss to the New York Mets.

"There's some frustration within our ballclub," Melvin said. "A couple of players get upset, then the manager gets upset. We saw a little of that exploding today. It was nothing more than letting it out."
