I know what you are asking-what the heck is FIP? According to The Hardball Times site, FIP is Fielding Independent Pitching, a measure of all those things for which a pitcher is specifically responsible. The formula is (HR*13+(BB+HBP-IBB)*3-K*2)/IP, plus a league-specific factor (usually around 3.2) to round out the number to an equivalent ERA number. FIP helps you understand how well a pitcher pitched, regardless of how well his fielders fielded.
With that explained, I give you the 2009 FIP leaders among starting pitchers courtesy of www.fangraphs.com:
One guy that stands out for me is Ricky Nolasco and his 5.06 ERA. Based on his outstanding peripherals, his FIP-3.35 is almost 2 runs lower than his ERA of 5.06. He will be someone to target on the cheap in 2010. His LOB% of 61%, or runners stranded, is extremely low and should increase in 2010, which will lower his ERA.
Joel Pineiro is another guy that stands out only for his low LOB% of 66.9%. His FIP wasn't much lower than his ERA, so I have to explain that is due to how low WHIP of 1.14.
