The Dulling of Mariano’s Cutter

Mariano Rivera picked up his 24th save last night as the Yankees defeated the Rays, 5-4. There are few pitchers who have provided the degree of reliability that Mariano has over the years. He’s also done it with style and grace and has been a great representative of everything good about baseball.

But even the greats show their age and that is beginning to happen to Mariano as you will see in my latest analysis for BaseballAnalytics.org.
