Everyone spent the last three years obsessing over "The Big Three." We talked about Marcelo Mayer, Roman Anthony, and Kyle Teel until our lungs gave out. And look, it’s understandable. Seeing three top-tier position players hit the upper minors together is rare. But while everyone was staring at the box scores in Portland and Worcester to see how many homers Anthony hit, something weird happened. The Boston Red Sox actually started developing pitchers.
Honestly, for a long time, the Red Sox pitching prospects were basically a punchline. You’d have a guy like Bryan Mata show flashes and then get hurt, or a mid-tier arm that never quite found a second gear. But the 2026 outlook is fundamentally different. The "Andrew Bailey effect" is real, and the farm system is finally spitting out arms that throw 100 mph with actual, honest-to-god extension.
If you aren't paying attention to the mound right now, you’re missing the actual story of where this team is going.
The Payton Tolle Era Is Already Here (Sorta)
Let’s talk about the giant in the room. Literally. Payton Tolle is a massive left-handed human being who has basically broken every "slow build" rule the Red Sox used to follow.
Last year was a fever dream for him. He went from being a second-round pick out of TCU in 2024 to pitching in the MLB playoffs in 2025. Think about that for a second. Most guys are still trying to figure out where the best Chipotle is in High-A Greenville at that stage of their career. Tolle was staring down hitters in October.
The numbers from his first MLB stint (6.06 ERA) look a bit ugly on paper, but scouts are obsessed with his "stuff." We’re talking about a 96 mph heater that touches 101 mph from a release point so low and an extension so long that hitters feel like the ball is being released halfway to the plate. MLB Pipeline just ranked him as the No. 2 left-handed pitching prospect in all of baseball for 2026.
He’s going to be in the rotation. Or the bullpen. Or both. The point is, he’s 23 and already has the "best fastball" in the system according to the recent executive surveys. He needs to refine the command—he's still a bit wild—but the ceiling is a legitimate frontline starter.
The Forgotten Man: Luis Perales and the 100 MPH Return
If you want to sound like you really know your Red Sox pitching prospects, you bring up Luis Perales.
Perales was the "it" guy before he blew out his elbow in June 2024. Tommy John surgery is a thief of time, and it stole almost all of his 2025 season. But keep this in mind: when he finally came back in September 2025, he wasn't just "fine." He was throwing 101 mph in the Arizona Fall League.
The Red Sox are in a bit of a weird spot with him because he’s on the 40-man roster but has almost no experience in Triple-A. He’s 22 years old. He's undersized. Some people think his future is in the bullpen because his delivery is high-effort, but the "stuff" is undeniable.
- Fastball: 70 grade (Elite)
- Secondary: Plus splitter and a gyro-slider
- The Risk: Only one minor league option left (unless they get a medical exception)
Basically, 2026 is the "prove it" year for Perales. If he can throw strikes in Worcester for two months, he’ll be in Boston by the All-Star break.
Why the Elmer Rodriguez-Cruz Trade Still Stings
We have to be honest here. Not everything is sunshine and rainbows in the development path. One of the most annoying things to happen recently was the trade that sent Elmer Rodriguez-Cruz to the Yankees for Carlos Narvaez.
At the time, people thought, "Okay, we need catching depth, and Rodriguez-Cruz is just a skinny kid in A-ball."
Wrong.
Since joining the Yankees, ERC has turned into a monster. He put on weight, his velocity jumped to 99 mph, and he posted a 2.64 ERA in Double-A last year. He’s now a top-100 prospect for our biggest rival. It’s the kind of trade that might haunt the front office if Narvaez doesn't keep hitting like a maniac. It shows that the Red Sox system can identify talent, but sometimes the "training wheels" they put on young arms might be a bit too tight.
The Next Wave: Connelly Early and Hunter Dobbins
If Tolle is the superstar, Connelly Early is the technician. Another lefty who debuted in 2025, Early actually pitched better than Tolle in his brief MLB look. He had a 2.33 ERA and a ridiculous 29-to-4 strikeout-to-walk ratio.

He doesn't have the 101 mph gas, but he understands how to tunnel his pitches in a way that makes hitters look stupid. He’s the "high floor" guy. You can bank on him being a solid No. 4 starter for the next six years.
Then there’s Hunter Dobbins. He’s 26 now, which feels "old" for a prospect, but he made his MLB debut in April 2025. He’s a survivor. He had Tommy John before he even got drafted. He’s got that "pitchability" that coaches love. He might not ever be an ace, but every team needs a guy who can give you 150 innings of 4.20 ERA ball without complaining.
What This Means for Your 2026 Expectations
The Red Sox rotation used to be a game of "let's hope this veteran on a one-year deal doesn't fall apart."
Now? It’s a youth movement.

The biggest misconception is that the Red Sox don't have pitching. They do. They just haven't had it all at once in a long time. Between Tolle, Early, and eventually Perales, the home-grown core is finally catching up to the hitters.
If you're watching the WooSox or following the farm this year, don't just look at the ERA. Look at the "whiff rate in the zone." That's the Andrew Bailey metric. If a kid is throwing strikes and getting swings-and-misses inside the box, he's the real deal.
Actionable Insights for Red Sox Fans:
- Monitor the 40-man: Luis Perales is out of options soon. He has to be on the roster or he has to be good enough to stay in the Bigs.
- Watch the Lefties: For the first time in forever, the Sox have two elite LHP prospects in the Top 10 (Tolle and Early). This changes how they match up against the Yankees and Orioles.
- Velocity isn't everything: Keep an eye on Kyson Witherspoon and Jojo Ingrassia. They are the "stealth" names that could jump into the Top 10 by mid-season.
The days of the Red Sox being a "hitting only" organization are over. It’s messy, and some guys like Rodriguez-Cruz will get away, but the factory is finally open.
