World Series champion Tim Lincecum uses his legs and hip rotation to generate momentum and energy while pitching. His leg stride is amazing - 7.5 feet. The arm comes along for the ride.
Lincecum learned his pitching mechanics from his father, Chris - who designed a weight-training program for Tim and videotaped his amateur games. Together, they reviewed the video the next day and the feedback helped Lincecum refine his pitching technique.
A New Ace for a New Era by Tyler Kepner
Lincecum credited a new workout, focused more on his legs and core muscles, with smoothing his mechanics and invigorating his preparation.
“After that,” he said, “it became more of just what I wanted to throw as opposed to how I was going to throw it.”
It also kept him strong down the stretch, with a 9-2 record and a 2.17 E.R.A. from Sept. 1 through the end of the World Series. Over 78 2/3 innings, Lincecum had 95 strikeouts and 17 walks, and opponents hit .188 against him. (source: NY Times)
