8 – Cliff Lee (2011)
In his first season in his second tour of duty with the Phillies, Lee had his best season since winning the Cy Young Award in 2008. Lee logged 232 2/3 innings with the Phillies in 2011, winning 17, completed a league-high six and struck out 238. Lee earned his third All-Star appearance, finished third in Cy Young voting, and 15th in Most Valuable Player voting. After three more seasons in Philadelphia, Lee retired with 143 wins and a 3.52 ERA.
7 – Roy Halladay (2011)
The late Halladay had a tall task trying to match his Cy Young Award season a year prior. He nearly did so, winning 19, completing a league-best eight games and posted a 2.35 ERA. In 232 2/3 innings, he struck out 220 and finished second in the Cy Young Award voting. He finished with a better ERA, fielding-independent pitching, and strikeout rate compared to 2010. It wound up being the last truly Halladay-esque season of his career.
6 – Steve Carlton (1977)
In his second of four Cy Young Award-winning seasons, Carlton helped lead the Phillies to 101 wins for the second straight season. He finished 23-10 with a 2.64 ERA. He completed 17 of his 36 starts, striking out 198 in 283 innings. Carlton led the league in wins for the second time in his career. In addition to winning the Cy Young, he finished fifth in MVP voting and was named an All-Star.
