In 2010, Tim Lincecum pitched the San Francisco Giants to a World Series Championship. Along the way, he won two Cy Young Awards. This fastball pro is at the top of his game, but it hasn't always been that way. As a kid, Lincecum was smaller than most of the other boys on his Little League and school baseball teams. He often spent more time sitting on the bench than he did playing on the field. He could have given upbut he didn't. Lincecum worked even harder, lifting weights and practicing on his own. The extra effort paid off. While he's still not the biggest pitcher in the majors, he's proven to be one of the best.
