Roy Oswalt struck out 15 batters in his first start with the Round Rock Express. Nolan Ryan, owner of the Express and Oswalt's idol, admired his calm demeanor and his aggressiveness so much that he successfully lobbied to keep Oswalt on the roster. As a result of his success at Round Rock, Oswalt was selected to play on the U.S. Olympic baseball team at the 2000 Summer Olympics. Oswalt went on to be a three-time All-Star in Major League Baseball. Roy Oswalt has hand signed this Round Rock Express Mini Batting Helmet.
