Sinkerballer Aaron Cook pitched 10 seasons for the Colorado Rockies, from 2002 to 2011, accumulating a record of 72-68. He was the Rockies' career victory leader until he was passed by Jorge De La Rosa in 2015. Cook's best season came in 2008, when he went 16-9, 3.96 in 211 1/3 innings and was named to the All-Star team. He pitched for Colorado in both the 2007 World Series and 2009 NLDS. His ERA of 4.53 with Colorado may seem high, but with his home park being Coors Field, it was actually good for a solid 106 ERA+, and in his prime, from 2004 to 2009, he was above 110 every year. After leaving the Rockies, Aaron spent the 2012 season with the Boston Red Sox, going 4-11, 5.65 in his final season.
