Mariano Rivera – 43
In his final season, Mo has been electric, with 35 saves on the season which is tied for third with Joe Nathan. He’s rocking a 2.44 ERA and has 42 strikeouts in 44.1 innings. The legendary closer is going out with a bang and is the oldest player on this list.
Watching any of these guys is a real treat, and a privilege to see players work so hard to continue living the dream that is baseball.
