Jorge de la Rosa

In the discussion about fantasy free agent signings several people mentioned Jorge de la Rosa of the Rockies. Knowing how bad he was in Milwaukee and Kansas City, I wondered over on Purple Row, "What happened to transform Jorge de la Rosa from a player that the Brewers and Royals were glad to be rid of to a player that the Rockies want to keep?" There were several answers, including working with a sports psychologist and working with Bob Apodaca, the pitching coach of the Rockies. Apodaca seems to be the answer, as de la Rosa's change has improved greatly since coming over to the Rockies. (Plus, confidence is a consequence of success, not vice versa.) Apparently he primarily throws the slider rather than the curve now, so his control looks better.  Here are data on runs above average by pitch type from fangraphs.com. A plus number means above average, a minus means below average. (In a sad note, I looked up Zach Duke's numbers. In 2005 his fastball was above average. Since then it has been well below average. In 2010, everything deserted him.)
