Roger Clemens was known as "Rocket", and for good cause - his blazing fastball. In 24 Major League seasons, pitching for the Boston Red Sox, Toronto Blue Jays, New York Yankees and Houston Astros, Clemens won 354 games and struck out 4,672 batters. Single signed Roger Clemens baseball with LE 71/300. Includes inscription "300W/4000k - 6/13/03". The signing date on the ball is exactly two months after the June 13, 2003 day in which Clemens, pitching for the New York Yankees against the St. Louis Cardinals at Yankee Stadium, won his 300th. game and struck out his 4,000 batter, both in the same game. The first time in MLB history that feat had been accomplished. Signature is in blue ball point pen. Includes Tristar and MLB holograms. Nice commemorative for a rare feat.
