Let’s get something straight right now. The Mets’ next real wave of hope isn’t a $300 million free agent, and it isn’t some shiny rumor floating through Hot Stove Twitter. It’s a 23-year-old right-hander most fans haven’t bothered to Google yet.
Nolan McLean and if you’re not paying attention to him now, you’re going to pretend you “always liked him” about 18 months from now.
This Is How Real Windows Start
Every contending era has that guy the one who quietly shows up before the banner years begin.
The Mets had Tom Seaver before the ’69 miracle. They had Dwight Gooden before 1986 exploded. They had Jacob deGrom before the rest of the roster caught up. Nolan McLean fits that same early pattern.
Not the hype, not the headlines, but the under-the-hood warning sign that something real is coming.
Who Nolan McLean Actually Is (Not the Myth)
Drafted in 2022 out of Oklahoma State, McLean was a two-way player in college, and infielder and pitcher before the Mets told him to focus on the mound. That alone matters. It tells you what kind of athlete you’re dealing with.
This isn’t some throw-hard-and-pray arm either. This is a pitcher who understands sequencing, movement, and how hitters think.
In his first full pro seasons, McLean has done one thing consistently: miss bats and limit damage.
Snapshot: Minor League Profile (through 2024)
- Age: 23
- Height/Weight: 6’3”, 210
- Throws: Right
- Levels: High-A → Double-A → MLB
- Role: Starter (with starter-level workload trends)
2023–2024 Combined (Approximate):
- ERA: ~3.30
- WHIP: ~1.20
- K/9: 9.8
- BB/9: 3.2
- Ground Ball Rate: ~48–50%
- HR/9: Under 1.0
Those aren’t “projectable maybe someday” numbers. Those are starter-quality indicators.
The Stuff: Why the Metrics Like Him
Let’s talk pitch mix, because this is where McLean separates himself from the “organizational depth” crowd.
Fastball
- Sits 94–96, touches 97
- High spin efficiency, late ride
- Plays better up in the zone than radar gun suggests
This isn’t just velocity for McLean, it’s shape. The pitch misses bats because it carries above barrels. Hitters swing under it more than expected.
Slider
- His best weapon
- Mid-to-high 80s with tight, late break
- Whiff rate north of 35% in the minors
This is the pitch that gives him legitimate swing-and-miss MLB upside against righties and lefties.
Changeup (The Separator)
- Still developing, but improving fast
- Flashes average to above-average
- Key to staying in the rotation long-term
The presence of a usable changeup is what separates “future reliever” from “real starter.” McLean has it, and it’s trending the right way.
Command & Pitchability
This is where the comps start to get interesting. McLean doesn’t just throw hard, he knows how to pitch. His walk rate has consistently improved as he’s moved up levels, and his sequencing shows maturity beyond his age. He attacks early, thene expands late, and he doesn’t panic with traffic. That’s starter DNA.
The Advanced Stuff
Let’s talk indicators that actually predict MLB success.
K-BB% (Strikeout Minus Walk Rate)
This is one of the best predictors of future performance.
- League average: ~14%
- Solid starter: 16–18%
- Impact starter: 20%+
McLean has hovered in the 18–20% range, depending on level. That’s not noise. That’s legitimate.
Ground Ball Rate
Around 48–50%, which matters in today’s game. Fly-ball pitchers get punished while the ground-ball guys survive.
This makes him:
- More durable
- Less homer-prone
- Better suited for Citi Field
Batted Ball Profile
Opponents don’t square him up often. His hard-hit rate allowed is consistently below league average. When hitters do make contact, it’s usually weak or on the ground. Translation: fewer “oh no” moments.
The Quiet Comp: A Young Aaron Nola Type
No, I’m not saying he is Nola, but the profile is similar:
- Not overpowering
- Clean mechanics
- Strong command
- Thinks his way through at-bats
- Gets better with experience
Those are the guys who age well. The ones who give you 180 innings of 3.50 ERA ball every year without drama, and frankly the Mets need that more than another high-variance flame thrower.
Why This Matters Right Now
The Mets are in a transitional moment. The big-money era got messy. The farm system is reloading, and fans are starving for signs of a sustainable plan.
Here’s the truth nobody wants to say out loud:
The next great Mets team won’t be led by a $300 million signing. It’ll be led by a pitcher you weren’t paying attention to yet.
McLean is that kind of pitcher. He’s not flashy, or loud. He just gets freakin’ outs folks, and historically, those guys end up meaning everything.
The Bigger Picture
If you’re waiting for the next “face of the franchise” to come from free agency, you’re missing the point. Every great Mets era had an internal foundation:
- Seaver grew with the franchise
- Gooden came up and exploded
- Wright was homegrown
- deGrom was developed, not bought
McLean fits that lineage. He might not be the headline yet, but he’s the kind of pitcher you build stability around.
When McLean starts stacking quality starts in Queens, people will pretend they saw it coming. You’ll know better.
Final Thought (And the Challenge)
This is the kind of player you remember before the hype. The kind you argue about at the bar. The kind you defend when the ERA bumps early. So here’s the question for you:
Is Nolan McLean the next real Mets cornerstone, or just another name fans will forget in three years?
Sound off in the comments. Argue with me., but make sure you bring receipts to back up your claim.
