When Fangraphs.com and Leverage Index Collide

Mariano Rivera, on a PA-by-PA basis, has faced leverage of 2.00 this year. However, when he came into the game, the LI was 1.88. And, in each inning that he entered, he was at 1.91. He was pulled two times out of 52 games, and when he was pulled, the LI was 2.35.
When he’s on the mound, he advances the win probability by a total of +9.80 by getting outs, but allows the other team to gain on the Yanks a total of -7.01 by letting them get on base or moving over.
A superb implementation by Fangraphs.
