As a newcomer to Purple Row I have a question: 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? In 2007 his xFIP with the Royals was 5.11. In 2008 with the Rockies it was 4.06, which is a major change. To be sure, he still walks too many, but he is a pitcher than many clubs would be happy to have. What happened?
