The joke I made with a scout a few months back on Jasa and think I brought it back up on the podcast is the team is going to lock Carson in the Sloan weight room with a stair climber when he gets down to AZ. He’s gonna come out with Mark Prior calves and throw 102.
Concerning some of these fastballs, there’s a lot they could do, but also they’re making a bet on supination and spin. Big deep arsenals but the trade off on that is side spin meaning those fastballs often don’t pop on the metrics as often. There’s still work to be done with them and usage is critical. The fastball often acts as what some player’s cutters are - bridge pitches and barrel suppressors. Then you beat guys with harder cutters that can be gyro sliders, hard curveballs, sweepers, and an arm-side offering like a changeup or split. Try to get as many of these pitchers with three fastballs (cut, 4s, sinker), multiple breaking balls, and one arm-side changeup or split.
