I just don't get why the umpires so often let things escalate to the point that everything gets so out of hand. I think it was dumb to retaliate when it wasn't intentional, but after Happ threw at Headley the first time, warnings could have been put in place there, as that one obviously was. That likely would have ended things. But they didn't, so fine, you f***ed up there. Then how do you not toss Severino after that first pitch to Smoak? What makes it even more strange is how he looked like he was about to eject him and then just didn't. So while this idiocy was started by the Jays, the umpires could have put a stop to it almost immediately, but obviously didn't. I'd like to hear why, but that isn't about to happen.
