(Born Aug. 04, 1962) Roger Clemens is considered by many to be the greatest pitcher ever to play baseball, and at the very least among the top 5. Starting his career with the Boston Red Sox in 1984, Clemens dominated batters for over a decade on that team, winning three Cy Young Awards and being robbed of a fourth. Perceiving that his skills were fading, the Red Sox let the Rocket walk away. He went on to win four more Cy Young Awards, two for the Toronto Blue Jays, one for the New York Yankees and one for the Houston Astros.
