They often meet with success when they become a starter. There is no substitute for speed. I will take a pitcher with lots of strikeouts over a control guy any day. That said, the real trick is to watch out for pitchers who start out with good control and then develop into strikeout pitchers. Again, watch that strikeout-walk ratio.
Wins are meaningless.
Never, never, use them to determine the value of a pitcher. This is by far the biggest mistake losing owners make. They miss the Rosado's, Hitchcock's, and Suppan's. Pitchers should be expected to tail off when they reach the Major Leagues. Wait a few years for their talent to emerge.
