8 – Cliff Lee (2009, 2011 – 2014)
Lee likely would be much higher on this list had he spent more time in Philadelphia. He was an All-Star in 2011 when he won 17 games and again in 2014 as a 14-game winner. He struck out 200 or more and logged 200 or more innings each season from 2011 through 2013. Lee compiled 48 wins and a 2.94 ERA in 118 starts with the Phillies.
7 – Roy Halladay (2010 – 2013)
Like Cliff Lee, the late Roy Halladay would be significantly higher on this list if he had spent more time in Philadelphia. Halladay was the Cy Young Award winner in 2010, leading the league in wins, complete games and shutouts. No one will forget the perfect game against the Marlins and playoff no-hitter against the Reds in the same season. Halladay won 19 games in 2011, again leading the league in complete games. Injuries took their toll on Halladay, limiting his effectiveness over his final 38 starts, going 15-13 with an ERA of 5.15 in 2012 and 2013.
