Earlier today I discussed a Bill James observation that Coco Crisp played an excellent centerfield over the last two weeks. I've looked that the probability of his putouts using last year's probabilistic model of range (PMR). Bill was right on.

This season, Crisp caught nine balls that weren't caught last year. There was a small sample size on each of those, so zero might not be accurate, but nine of those catches came in the last two weeks. Overall, he caught fifteen balls where the probability was less than or equal to .5, and 13 of those came from 4/23 on. If I had data on balls he didn't catch, we could do a complete analysis, but it sure looks like Bill's observation is true, that over the last two week Crisp is making difficult plays.
