Spoiler: Ugghhhhhh
Perhaps you've noticed that multiple starting Giants outfielders are on the DL because they got hit by pitches. If not, that's okay; it's flown under the radar a little bit. As to the reasons that NL pitchers can't stop injuring Giants by throwing baseballs at them, I haven't heard anyone say it's jealousy of all the World Series rings. Not one single writer or player has gone on the record to say each of the guilty pitchers wishes they had the feeling of having won several championships, and was acting out based on poor impulse control.
