No. 3 Starter: RHP Tim Lincecum (2010-15)
Stats: 68-66, 4.02 ERA (89 ERA+), 1.34 WHIP, 1,028 K, 1,045 IP, 4.1 WAR
Before you wonder why Tim Lincecum is not the No. 1 or No. 2 pitcher on the All-Decade staff, keep in mind that his back-to-back Cy Young wins came in 2008 and 2009, and therefore were not part of the conversation.
He was an All-Star in 2010 (3.43 ERA, 231 K, 212.1 IP) and 2011 (2.74 ERA, 220 K, 217 IP), before his ERA spiked to 5.18 during the 2012 season and he was never able to regain his elite form.
As the ace of the staff during the 2010 title run, he threw a two-hit shutout in Game 1 of the NLDS, racking up 14 strikeouts along the way. He finished that postseason with a 2.43 ERA in 37 innings, tallying four wins and one hold out of the bullpen.
So while he was only in frontline form for two seasons during the decade, it was still more than enough to earn him the No. 3 spot on the staff.
