Wear your protective gear during all practices and games, especially if you're a catcher — those fast balls can pack a punch! Don't forget to warm up and stretch before each practice or game. In the infield? Stay behind the base on any throw. You'll avoid hurting yourself — and the base runner. In the outfield? Avoid bloopers with your teammates by calling every fly ball loudly, even if you think nobody else is close by. And in the batters' box, wear a batting helmet and use a batting glove to protect your knuckles from those inside pitches. If you think a pitch is going to hit you, turn away from the ball and take it in the back.
Throwing those fastballs can really take a toll, so if you're a pitcher, make sure to get plenty of rest between games, and don't pitch more than 4-10 innings per week.
