Rapper T.I. picked up a new skill on the set of Denzel Washington's new movie hit AMERICAN GANGSTER - he learned how to throw a baseball. The young star - real name Clifford Harris - plays the baseball prodigy cousin of Washington's drug dealer character in the biopic, and he actually had to perfect a pitch for one family party scene. T.I. says, "We had a pitching coach on set who played or coached in the minors. They worked with me every day for two weeks for two hours a day before we actually had to use it. "(They had me throwing) knuckleballs, fastballs, curveballs."
