Did you know that Rivera was a starter when his career began?? Yep, the dude who had 652 career saves (most ever) and 1,173 Ks over 1,283.2 innings, started 10 games in 1995 during his rookie campaign (and more in the minor leagues). Rivera was a 13x All Star, WS MVP, ALCS MVP, AS MVP, and ammased 56.2 career WAR
Fun fact: Rivera gave up 5 runs and 8 hits in his first big league start against the Angels.
Halladay tragically passed away in 2017 so wasn’t able to see himself enter the HOF, but I’m sure he knew it was going to happen.
