Doyle was a steady member of the Coastal Carolina Chanticleers rotation in 2023, and continued to get better as the year went on. He transferred to Ole Miss in 2024 but only stayed at the school for one year before heading to Tennessee. The stuff exploded on Rocky Top.
Doyle has been up to 99 and will sit 94-97 from the third inning on with considerable carry and arm-side run. It's a devastating fastball and coming from the left side makes it all that much more impressive. The fastball is without question a 'plus' offering and it'll flash 70-grade traits early in outings with plenty of fuzz up in the zone. Doyle lives on the top rail and is extremely effective because of it. While the velocity and shapes are both exquisite, Doyle is just an average extension guy but the stuff is so big it's hardly effected him to this point. It's possible professional hitters will pick up the fastball out of his hand better than current competition, however that won't dilute the fact it's at least a plus pitch.
He's shown above average command for the fastball too. He's usually around the zone and walks haven't been much of an issue, but putting the pitch where he wants is fringy.
The secondaries are more of a work in progress in large part because he never really had to show them much in 2025, They've shown enough to project effectiveness to the next level.
His splitter and cutter/slider are both effective, the splitter especially. The splitter has a chance to become a plus pitch if shapes and conviction alone are any indication of future projection. It's 85-87 with big arm-side run and even better vert.
The cutter is short with firm, slippery tilt. It's effective getting hitters off the fastball and Doyle has shown the ability to keep it under right-handers' hands and back-door it as well.
There's also a bigger sweeping slider with considerable tilt and sweeping action in the low-80s. That pitch will probably need to be thrown a bit harder in professional baseball with the current shapes he's generating.
Doyle does have a deeper arm action and there's some effort with his delivery leading to the aforementioned command shakiness. When you combine the struggle to hold velocity into the middle innings, the fastball-heavy usage rates, the shaky secondaries and unconventionally long arm action, it's fair to question whether or not Doyle will end up in a high-leverage relief role as a pro. There's a lot to like with this arm, even if it ends up being a weapon at the end of games rather than a workhorse at the beginning of them. There's a path to Tarik Skubal here, but an even more likely avenue toward a Tanner Scott outcome.
