His 2.05 ERA+ is ridiculous and easily the best of all-time for pitchers with more than 1000 IP in their career. However, his 0.71 ERA (139 IP) in the post-season is even more preposterous. Is he the greatest closer in baseball history? (Source: http://espn.go.com)

No question he is best closer in history. What makes him even more impressive is how often he is a two inning closer. Most closers don’t enter a game until the last inning. Rivera enters 8th inning games more than any I have ever seen.
