The Diamondbacks have signed right-hander Kris Benson to a minor league deal, adding starting pitching depth to the organization as Brandon Webb slowly works his way back from shoulder surgery. Benson will make $650,000 if he?s in the big leagues and has a chance to earn another $100,000 based on games started. He gets $25,000 each for reaching 5, 10, 15 and 20 starts.
