Timothy Leroy Lincecum (born June 15, 1984, in Bellevue, Washington) is an American baseball player who is a starting pitcher for the San Francisco Giants of Major League Baseball. He is nicknamed "The Franchise" and "The Freak."

He throws right-handed and bats left-handed. Lincecum is known for his long stride, unorthodox mechanics, and ability to generate high velocity despite his slight build of 5'11", 172 lbs. Lincecum won the NL Cy Young Award 2 years in a row (2008-2009), becoming the first second-year player to win the Cy Young since Dwight Gooden and Bret Saberhagen both won in 1985. His repertoire includes a two-seam fastball that reaches well into the mid-nineties, a changeup he grips like a splitter, a curveball notable for its sharp breaking action, and a slider. He also has a four-seam fastball, but rarely uses it.

Lincecum attended Liberty Senior High School in Renton, Washington, where he played two seasons of varsity baseball. As a senior, he won state player of the year and led his school to the 2003 3A state championship.
