When somebody pops up a pitch, inevitably, the pitcher will point up in the air as if to say "Look!! There's the ball!!" Why do they do that? Do they think the fielders have been standing and watching the crowd and forgot to watch the pitch coming in to home plate? Maybe it's just a natural reaction. I've never seen a coach teach pitchers to point up in the air when somebody hits a pop up so I know it isn't taught, it must just be a natural reaction. Natural only for pitchers, that is.
