I played right field mostly, and I could always get a jump on the direction of the ball before the batter actually hit it, based on the pitch location and the swing. I don’t know why, I just could. I can still tell if a football is on target the second it leaves the quarterbacks hand, and whether a basketball is going in the second it leaves your hands. I have no idea why, but I’ve always had these senses.
There’s a former Marine fighter pilot (Korea)/Pistol Team member who stops by the watering hole now and then. He say’s he can’t explain his vision, either—just that “the damn ten-ring looks like a dinnerplate to me at 50 yards.”
And I have never been able to judge a fly ball. I have above average athletic abilities in most things I have ever tried, but not shagging flys.
