 There's never going to be another Mariana Rivera. Now I'm not just saying that, I mean it. Check this out. At the most inconsistent position, Rivera had 43 saves in 1997 and 44 saves in 2013. That's 16 years apart. Rivera pitched during an era of huge offense. The American League ERA during Rivera's career from 1995 to 2013 was 4.49. His career ERA was 2.21, so Moe's was less than half the league average. And he was absolutely dominant in the postseason. His 0.70 career playoff ERA in 141 innings is a record. He also has the record for the most postseason saves with, of course, 42. Now you're probably asking yourself, but somebody's got to catch him, right? Well, Craig Kimbrel may be the closest with 333 career saves at just 30 years old. He's averaged 41.5 saves over the last eight years. However, he'd have to average 40 saves over the next eight years to catch Mariana's record of 652. And that's my stance on why there's really never going to be another Mariana Rivera.
