For major league pitchers, 20 wins has always been the benchmark of an exceptional MLB season and to some extent, a career.
In fact, almost every one of the 51 pitchers in the Hall of Fame won 20 games in a season at least once in their career—relief pitchers excluded.
After a 2009 season in which no pitcher won more than 19 games, three pitchers were able to reach 20 wins in the 2010 MLB Season - Roy Halladay (21), CC Sabathia (21) and Adam Wainwright (20).
Halladay had already accomplished the feat twice with the Toronto Blue Jays (2003, 2008) before joining the Philadelphia Phillies in 2010, whereas neither Sabathia nor Wainwright had ever done so before.
Three pitchers finished only one win away from 20 - Ubaldo Jimenez, Jon Lester and David Price - while many others were able to win 17 or 18 games, begging the question:
Who Will Become Baseball's Next 20-Game Winner in 2011?
