Here is a fun story about the majority of Canadian Baseball player batting left handed due to playing hockey left handed as they grew up.
Why do so many Canadian baseball players bat left-handed? Jason Bay has a theory: When first handed a hockey stick, the typical Canadian kid grabs the end with his right hand.
“I don’t know the scientific approach to it,” Bay said Wednesday, “but that was the Baseball Canada consensus in the locker room — that it had everything to do with the hockey stick. Everything. I think it boiled down to being right-hand dominant and using that on the top of your stick as your control hand. That’s the best that we could come up with.”
According to various Internet entries, about two-thirds of NHL players shoot left-handed. Roughly 90% of the general population is right-handed.
