Why? He's clearly not doing it on purpose. I'm not saying he did, this really doesn't matter for teams. Of course it does. Players get hit by wild pitchers all the time. Players don't like it when the ball goes near their head repeatedly, intentional or not. Remember Chapman last year. Peavy is enough of a tough guy to hit someone in retaliation(Lester would too I bet), although he might be so desperately trying to conserve pitches that I wouldn't bet on it. Bochy seems like he runs a tighter/smarter ship than that.
