"When Nolasco is written about, "quality peripherals" invariably are mentioned. Fact is, Nolasco is not a "useful starter". He never seems to get the results the peripherals suggest he is capable of" Well stated. I'll go a step further. FIP, specifically, can be pretty misleading when used independently. Nolasco gets hit pretty well (opponents' .276/.320/.437) but FIP only accounts for home runs and walks, so all the singles, doubles, triples, successful bunts, sac flies, etc. are disregarded. He's a prime example of the limitation of this particular stat. Measured by FIP, he's a 3.80 pitcher, but in real baseball, he's a 4.50 pitcher. For some pitching styles, the peripherals do a nice job of predicting success/failure, but for Nolasco's entire career he's underperformed his peripherals. These measures clearly aren't a reliable guide for him.
