Not just winning, but winning more often than losing. To make this chart you first need at least 1,000 innings pitched. This eliminates those one year wonders with a winning percentage of 1.000. After they put that experience under their belt, they then need some seriously good pitching skill, a good team around them, and a lot more victories than losses.

Note: A bold faced entry denotes that the player was active during the previous Major League season.
