Regarding positions in HS, know them all. Obviously lefties are limiited. Had a kid who'd been playing only IF in rec/travel/middle school say at a practice, they only know IF. I told them if you want to play in HS, you better learn as much much as you can wherever you can. Hitting will get you more opportunities, but you should never pigeonhole your abilities to a subset. Coaches like players they feel confident they can put anywhere.
