Good question. When I was young (ok, a LONG time ago) I would prefer to catch with my left hand since it is the hand I could get highest into the air (for high throws), that's how it worked for me in basketball. Trouble is, I am a lefty thrower. I had to learn to use a mitt on my right hand.
Mythical SF Chronicle scouting report: "That Jeff runs like a deer. Unfortunately, he also hits AND throws like one." I am Venus DeMilo - NO ARM! I can play like a big leaguer, I can field like Luzinski, run like Lombardi. The secret to managing is keeping the ones who hate you away from the undecided ones. I am a triumph of quantity over quality. I'm almost useful, every village needs an idiot.
