When you walk into the gymnasium at Trinity High School in Louisville, you’re basically smacked in the face by a wall of green and white championship banners. It’s overwhelming. Most people look at that sea of felt and think "football factory." Honestly, who can blame them? With nearly 30 state titles on the gridiron, the "Rocks" are a national brand in pads and helmets.
But there’s a shift happening. A big one.
Trinity High School baseball isn't just some spring hobby for kids waiting for summer football camp anymore. If you haven't been paying attention to what Coach Rick Arnold has been cooking over on Shelbyville Road, you’re missing the best story in Kentucky high school sports. The program just secured the 2025 KHSAA State Championship in June, and they didn't just win it—they did it with a 2-1 walk-off thriller in nine innings against Pleasure Ridge Park. That’s back-to-back dominance when you realize they also took the crown in 2021.
The Rick Arnold Era: More Than Just Wins
Rick Arnold is a 1986 Trinity alum. That matters. When you talk to people around the program, they don’t just talk about batting averages or exit velocity. They talk about "The Trinity Way."
Arnold has been at the helm for over a decade now, and his record is kind of ridiculous. We’re talking over 330 wins against fewer than 60 losses. You don’t stumble into a winning percentage like that. He’s turned the program into a pro-style pipeline. While other schools are struggling to find a consistent starting rotation, Trinity is out here producing MLB Draft picks like it’s a job.
Take Brandon Pfaadt, for example. He was a 2017 grad who went on to lead the Arizona Diamondbacks’ rotation in the World Series. Then you’ve got Daylen Lile, Ben Metzinger, and Korbyn Dickerson. These aren't just "good high school players." These are guys who are literally getting paid to play the game at the highest levels.

Why the 2025 Season Changed Everything
Last year was special. The Rocks finished 38-3. That’s not a typo. Losing only three games in a sport where a weird bounce or a bad umpire can ruin your week is almost impossible.
The state title game against PRP (Pleasure Ridge Park) was basically a microcosm of why this team is different. It was tense. It was sweaty. It went into extra innings. In the bottom of the ninth, the Rocks found a way to walk it off. That grit? That's what people usually associate with Trinity football. Now, it's the baseball team’s identity.
It’s Not Just Kentucky: The Trinity Brand
We should probably clear something up because Google gets it confused all the time. If you’re searching for "Trinity High School baseball," you might be looking for the Trojans in Euless, Texas, or maybe the Pioneers in Manchester, New Hampshire.
The Texas Trinity (Euless) is a whole different beast. They play in the brutal UIL Class 6A. While their football team is legendary for the "Haka" and multiple state titles, their baseball program is a consistent playoff threat too. They’ve got a massive rivalry with L.D. Bell that basically shuts down the Hurst-Euless-Bedford area.
Then you’ve got the New Hampshire bunch. The Trinity Pioneers in Manchester are currently in a massive "reset" phase under Coach Matt Bouchard. After some lean years (we're talking 1-17 and 2-17 seasons), Bouchard has actually started to turn the ship around. In 2025, they went 20-4. That’s a crazy turnaround for a program that was essentially at the bottom of Division I just three years ago.

But honestly, when people talk about the "powerhouse" Trinity in 2026, they’re usually talking about the Rocks in Louisville.
What Scouts Are Looking At Right Now
If you’re a college recruiter or just a local fan, the 2026 roster at Trinity is stacked. You’ve got guys like Jonah Williamson (a 6'3" catcher/pitcher hybrid) and Matthew Robaugh who are drawing eyes.
The depth is what kills you. Most high schools have one "ace" on the mound. Trinity has a staff. They play a schedule that takes them all over the country, facing top-tier talent in Florida and Georgia during the early spring. By the time they hit the KHSAA regional tournament, they’ve already seen 95-mph fastballs. Nothing rattles them.
The Facilities Arms Race
You can't talk about Trinity baseball without mentioning the setup. They don't just play on a patch of grass. The investment in their facilities—from the turf to the hitting tunnels—rivals some small colleges. This is why kids from all over Jefferson County and beyond are trying to get into the school. It’s an ecosystem designed to win.
The "Football School" Myth
There used to be this joke that if you played baseball at Trinity, you were just a football player who didn't want to run track in the spring.

That's dead.
Nowadays, the baseball players are specialists. They’re year-round athletes. They’re in the weight room at 6:00 AM focusing on rotational power, not just bench pressing for the sake of looking big. The program has its own identity now. When you see that shamrock on the cap, you know you’re in for a long afternoon.
How to Follow the Rocks in 2026
If you’re trying to keep up with the team this season, GameChanger is basically your best friend. The school is incredibly active on social media, but the real data is in the live-scoring apps.
- Check the Seventh Region Schedule: This is where the real wars happen. The 7th Region in Kentucky is arguably the toughest in the state.
- Watch the Alumni: Keep an eye on the MiLB box scores for guys like Daylen Lile and Korbyn Dickerson. Their success is the best recruiting tool the high school has.
- Attend the Invitational: If Trinity is hosting a spring tournament, go. You’ll likely see three or four future Division I players on the field at once.
Actionable Steps for Aspiring Players
If you’re a middle schooler or a parent looking at Trinity, understand that the competition starts before you even put on the jersey.
- Attend the Summer Camps: Coach Arnold and his staff run these, and it’s the best way to get on their radar early.
- Focus on Versatility: One thing Trinity loves is a "UT" (Utility) player. If you can pitch and play a solid shortstop, your value triples.
- Academic Check: It’s a private Catholic school. If your grades aren’t there, the best curveball in the world won’t get you through the front door.
The landscape of high school baseball is changing. It's becoming more professionalized, more data-driven, and more intense. Trinity High School isn't just keeping up; they're the ones setting the pace. Whether you’re a fan of the Rocks, the Trojans, or the Pioneers, one thing is clear: the name "Trinity" on a jersey usually means you’re about to play a team that doesn't know how to quit.
