They wouldn't be in a playoff position without the strong work done by a quartet of 22-24 year old rookie starters—Kyle Freeland, Jeff Hoffman, German Marquez, and Antonio Senzatela—but their workloads need management, and some of them already appear to be flagging. Senzatela has already pitched his way out of the rotation, Hofman has been cuffed for a 7.66 ERA over his last eight starts, Tyler Chatwood has struggled since returning from a calf strain, and they can't count too heavily on the returns of Chad Bettis (testicular cancer) or Tyler Anderson (left knee surgery). Chacin fared well during his 2009–14 run with the Rockies, pitching to a 3.78 ERA (120 ERA+). He's revitalized his career in San Diego (3.00 ERA/4.26 FIP), and he's dirt cheap, making just $1.75 million.
