fast reflexes are great but good anticipation is equally important.

I played 3rd base in college baseball and had what many thought were cat-like reflexes. Luckily I was pretty quick through diligent practice but what made me quicker than I really was was the fact that I knew where the ball would be going before it was hit. Out of the corner of my left eye I could see the ball being thrown, and when looking at the batter and when he swung, copared to where the ball was I could tell if he was swinging early or late and thus if it was coing my way. That's why it's so important NOT to telegraph your punches and to pick up on the things the other guy is doing that tell you when he's going to punch.

ps, some useless info: what is really hard for a 3rd baseman was when a left-handed batter swings late and the ball come at you. You don't have the luxury of seing where he is in his swing. Thus the ball just comes at you "without warning." It's jsut bang. all you see is the thng coming at you when it's almost too late.
