This will only be of interest to baseball fans: heatmaps of Rivera’s pitches. The control on display is quite phenomenal.

I’m less impressed by the comparison between Rivera and the league than by the comparison between Rivera and the other AL closers. The number of pitches thrown by the entire league over a season is almost guaranteed to result in a distribution like the one shown. To see how Rivera works the edges in comparison to Feliz, Soria, and Soriano, however, is extremely telling. Greatest closer of all time. (Oh yeah: his postseason ERA is 0.72.)
