Rivera's pitches

Interesting data about Rivera's pitches - I found it particularly interesting that in a sample of about half of his pitches this season, he only threw a single non-cutter to left handed hitters. Righties saw about two-thirds cutters and one-thirds fastballs, with nearly all of the fastballs being inside off the plate.

So basically, it looks like Rivera only uses the straight fastball as a way to back righties off the plate.
