Eno Sarris of The Athletic has a terrific deep dive into the improvement Cole Ragans has made.
“My first outing with Kansas City (in Triple-A Omaha), I gave up eight hits and six were to lefties,” said Ragans. “I said, ‘Oh my gosh.’ Zombro sent my xwOBA against lefties and it was ridiculous. In my head, I was like, ‘I need something that has a little more movement to get swing-and-miss off of lefties.’ A gyro slider, basically a three horizontal, three vertical, basically something to miss barrels with. With the cutter, they were micro-adjusting their barrel and killing it, shooting it the other way.
