Nicknamed the Freak, Lincecum is a shaggy-haired, skinny kid who looks more like a bat boy than one of the best pitchers in the majors.
Known as Doc, the bearded Halladay is bigger, stronger and can probably pass for a professor.
Lincecum is quirky. He has an unorthodox delivery, doesn't ice his arm, and munches on treats like Philly cheesesteaks or ice cream before starts.
Halladay is robotic. He has perfect mechanics, a tireless work ethic and doesn't let anything prevent him from following his routine.
Both pitchers were sensational in their postseason debuts last week.
