After a very impressive season in 2010, Halladay was projected to win over 20 games for the Phillies again in 2011. With five wins in nine starts so far in 2011, Halladay is on pace to win somewhere between 20-22 games this year.
Roy Oswalt has three wins in just five starts. At this pace, he is on track to win between 22-24 games on the year. The only concern with Oswalt is his health. He had a brief stint on the DL already in 2011 because of soreness in his lower back. If he can stay healthy, he has a very realistic chance to crack the 20-win mark in 2011.
Cole Hamels is also very close right now as well. Hamels has won four of his eight starts, giving him a projected win total between 18-20 in 2011.
Cliff Lee has struggled early in the season, but has always been dominant during the second half of the season. While he has won just two of his nine starts, he has not pitched terribly during that stretch. He has had control issues as of late. On Monday night against the Cardinals, he walked a career high six batters. If he can get his control down and stay aggressive to hitters, he always has the possibility to win over 20 as well.
These projected stats are just rough estimates based on win percentage, but Halladay, Oswalt, and Hamels all have very realistic shots at winning over 20 games for the Phillies in 2011.
