Since WW2, teams leading by 1-run after the 8th inning won 85.7% of the time. When leading by 2-runs it was 93.7%. When 3-runs it was 95.7%.
Over 2/3 (442] of Rivera’s 652 saves came with a 2-run (210), 3-run (180), or 4-run (46) lead when entering the game.
Basically, his 89.1% career save percentage was due to his team already having a 88% or better chance of winning anyway, according to league averages.

Reason: Changed 90 to 88 to better reflect weighted-average
