The thing is, this has come under two different managers and three different hitting coaches. We aren't unduly crowding the plate. It's... weird.
I think it's SSS. I see no reason why we'd be headhunted -- it's not retaliatory (our pitchers' HBP are average) and it's not an attempt to neutralize us (we've been meh during most of the period).
Gibson would kill any hitter active today. He would see the body armor and think, "challenge accepted."
Maybe they're just not good at dodging inside pitches. Might be time for the manager to walk into the clubhouse with his tool box. "If you can dodge a wrench, you can dodge a ball."
