Let me guess, this is the next Cohen move that will be bitched about? I don't see any way having a bunch of HBP can be construed as a bad thing. If you lean into it, the ump calls it. If it's legal, it's a base.
Only bad thing I can think of is Renfroe getting hit on the hand, when he tried to get out of the way. I guess Cohen coached that one, too.
