Looking back I would have probably forced my son to hit left handed early on, but who knows? Maybe he wouldn't have turned into a college-level hitter from that side.
JBOG and @Roadrunner. It's been a while since I've heard it from him, but RipkenFanSon (3.9 HTF) used to chide me for not teaching him to hit left when he was younger. I wish I did. Son is definitely dominant right all the way around, though. He would tell me how much higher his BA/OB% would be without all those ABs where he was"out at first by a step."
And his non athlete younger brother.. he's lefthanded.
