Stuff+, a metric that captures the physical qualities of a pitch, was born in 2020. Since the date, no pitcher has thrown 250 innings and has a higher Stuff+ than Jhoan Duran. While there are single pitches that can outpace some of his offerings, Duran has evolved into a wide mix reliever with multiple dominant offerings. A 97 mph split-finger he can command enough to throw nearly half the time? Check. A triple-digit heater? Of course. An 88 mph power curve? Why not. An 89 mph sweeper, tied for the hardest in the game? Yep. Hey why not throw in a second power changeup at 89. Duran: just dripping with stuff.
