re: What sports skills are most difficult to learn

I'll assume you mean learn and be able to perform effectively in competition.

if not,, I don't care ,,this is my list top 5

12- the skating alone makes this a tough one to learn and be able to play effectively,, then toss in all the other skills required.

2 Hitting a baseball is the single toughest thing to do in sports

3 throwing strike and not being pounded ,, almost as tough as hitting

9 throwing a ball accurately under duress, right up there with 2&3

1- Playing infield,, esp SS. not something you can just learn and do, takes years and years to be good at it
