Charlie Sheen -- Batting Practice Cut Short By Injury

Charlie Sheen spent his Sunday afternoon doing what he loves the most -- no, not that ... he played baseball at Chase Field, home of the Arizona Diamondbacks.

Sheen was taking batting practice with a few of his friends when he says he ruptured the ulnar nerve in his elbow. He can barely grip the bat now and it kept him from hitting any out of the yard.
