The Indians have one of the top pitching staffs in baseball. Carl Willis can’t claim all of the credit — his 2015-17 seasons were spent in Boston — but he’s certainly played a meaningful role. The veteran pitching coach has done an exemplary job since coming to Cleveland one year ago this month.
An understanding and appreciation of analytics is a big reason why. At the age of 57, Willis possesses an admirable blend of old-school acumen and the new-school applications that augment the ABCs of the craft. His resume includes a stint as a special assistant to baseball operations, as well as 15 seasons as a big-league pitching coach. Four different hurlers have captured a Cy Young Award under his tutelage.

Carl Willis on notable changes in the game: “There have been two major changes. The first one is that swings have changed. Because they’ve changed, how you pitch — how you attack those swings — has changed. Certainly, when I played, and when I first became a coach, it was always, ‘You’ve got to command the bottom of the strike zone. You have to pitch down. It’s money.’
“Nowadays, with the evolution of launch angle, we’re seeing the top of the strike zone, and above, becoming much more of a weapon. That’s how we’re attacking those swings. Of course, there are still pitchers who pitch at the bottom of the zone. It depends on your repertoire and, obviously, the action you get.
“Because of how hitters are being attacked now, velocity has probably become more important. But velocity doesn’t matter if you can’t command it. Nowadays hitters see velocity every day. It used to be Nolan Ryan, Doc Gooden, J.R. Richard. Those guys separated themselves with their velocity. They had other pitches as well, but they had that superior velocity. Now, every time the bullpen door opens, it’s 97-98. Hitters are acclimated to it.
“The other major change is analytics. For me, it’s really more the science and understanding of what the baseball is doing. And it’s not only how we’re able to evaluate pitchers in that regard. It’s how we can help them create some of those actions, some of that spin. And I think it’s [spin] axis more so than [spin] rate. There’s a better understanding of what a pitcher is going to be and what he’s going to have to do to succeed with what he brings to the table.”
