Claim this autographed Yankee Batting Helmet of baseball great Roger Clemens. Your children will love it! The Rocket, over 300 wins as a starter, holds a definite spot in the Hall of Fame. And who ever said you can't play ball when you get older...??? At age 43, the Rocket has a 2.7 ERA and a 2:1 ratio of strikeouts to walks in his previous season with the Houstan Astros. Whether he comes back for another season or not, we know that the Rocket still has some engine fuel left in that arm. Courtesy of Chris DiMarco.
