He was one of the most dominant pitchers in baseball for his entire career. From 2003-2008 he had a 143 ERA+, gave up a miniscule 0.6 HR/9, averages 219 IP and sported a 2.46 K/BB ration. Then his arm basically fell off as he made one appearance in 2009 and after several failed comeback attempts he retired today. That 219 IP average is also artificially lowered by his reduced appearances in his rookie year. His 162 game average is 227.
