Breaking down the Liriano numbers

Watching the elites fall after injury is always disappointing, but when it happens so early in their career it's even tougher to watch. Francisco Liriano had one of the great debut seasons with a 12-3 record and a 2.16 ERA. His K/BB was 4.50 and a final FIP of 2.55. He of course went on to Tommy John and has been trying to get back to that level since. He returned for 76 good innings, but that was supported by a low HR/FB of 7.7%.
