Any baseball fans here?
No questions. I'm just a lefty who enjoys baseball. Feel free to discuss.
Baseball is somewhat unique. In the top levels of the sport (MLB, MiLB) being left-handed limits a player to positions he can play.
I'm not referring to batting. Batters can learn to bat from either side of the plate. It has some hand dominance involved, but it seems to be easier to overcome that natural tendency. We see switch hitters quite regularly. I'm referring to the throwing arm. Very few, if any, players can learn to throw well with their non-dominant arm.
In the top level of the sport lefties can only play outfield, pitcher, or 1st base. To be a lefty in baseball you cannot expect to succeed at 2nd base, 3rd base, shortstop, or catcher. That limits you to 5 out of 9 positions, but really only 3 out of 7 positions, because all three outfield "positions" are all just "outfield" and fielders move around often.
Even with that limitation we see lots of lefties in baseball, particularly pitchers. There are advantages to being a lefty pitcher, including an easier view of a runner on 1st base. I certainly acknowledge that lefty arms do have advantages, but that does not discount their restrictions.
I'm at a loss to think of any other major sport where being a lefty limits a player's chance to play particular positions. Basketball? Football? Soccer? Hockey? I don't think so.
