Saves Aren't Very Predictive 2011


Saves_vs_fip_medium

R-squared shown for LOLs.

Digging around the "so obvious it hurts" saber-shelves today and figured you guys might like random shot at just how varied the spread on closer success has been in 2011. This data set is a scrape from Fangraphs and includes the top 35 relief pitchers with a save, and is set against their various corresponding FIP scores.

Huston Street is the obvious red flag with a higher FIP than all but four pitchers in this set. Craig Kimbrel is having a great year, and Papelbon has been effective despite not closing the deal on the "save." That said, if I'm Jonny Venters, I'm pissed for selfish reasons -- stuck setting up Kimbrell, his 2.13 FIP beats out Joel Hanrahan's 2.22 but has 20 less saves to show for it.

You’ve given Mr. Kimbrel an extra “L.”

An extra "L" for sheer ridiculousness, maybe?

That R² really is comical.

I’d love to see more graphs like this correlating (or, in this case, “correlating”) other performance metrics like K/9, WHIP, and even ERA.

Not that I think saves are a good stat at all but,

wouldn’t it be a lot more useful to look at say save% instead of number of saves.

Right.

Essentially what you’re seeing here is how poorly FIP in-sample predicts a pitcher’s save opportunities. You’ve got a lot of setup men on the left and full-time closers on the right.
