Before he was a unanimous AL Rookie of the Year or the face of a terrifyingly young Baltimore Orioles core, Gunnar Henderson was just a kid in Selma, Alabama, making high school sports look entirely too easy. Honestly, when you look back at his time at John T. Morgan Academy, it feels less like a scouting report and more like a tall tale.
He wasn't just good. He was "scary to pitch to" good.
Most people know Henderson as a baseball phenom, but if you only focus on the diamond, you're missing half the story. The athleticism that lets him range deep into the hole at shortstop and fire 90-plus mph lasers across the diamond was forged on the hardwood as much as it was on the dirt.
The Two-Sport Dominance at Morgan Academy
Gunnar didn't just play basketball to stay in shape. He was a monster. We are talking about a guy who was named the Alabama Independent School Association (AISA) Player of the Year in basketball. He averaged 17 points and 11 rebounds a game.
Think about that for a second.
A future MLB superstar was casually putting up double-doubles every night. His scouting reports from that era often mentioned his "shooting guard-like" movements. It’s that fluid, lateral quickness that makes his defensive ceiling in the majors so high. He wasn't just a big body; he was nimble. He had that rare "weightless" first step that allows a 6-foot-3 infielder to move like a guy four inches shorter.

But, yeah, baseball was always the main event.
Gunnar Henderson High School Stats: A Senior Year for the Ages
His 2019 senior season at Morgan Academy was, frankly, ridiculous. Let’s look at the numbers because they barely seem real:
- Batting Average: .559
- Home Runs: 11
- RBIs: 75
- Stolen Bases: 32
- On-Base Percentage: .634
- Slugging Percentage: 1.225
He led the Senators to a 30-2 record and the AISA Class AAA state championship series. Imagine being a 17-year-old pitcher in rural Alabama and seeing Gunnar Henderson step into the box. You've got a better chance of winning the lottery than getting a fastball past him. Marshall Watts, a rival coach at the time, once remarked that Gunnar hit the hardest opposite-field ball he’d ever seen—and that was coming from a guy who played in the SEC.
The Auburn Commitment and the $2.3 Million Gamble
Here is a detail that gets overlooked: Gunnar was supposed to be an Auburn Tiger.
He committed to Auburn during his sophomore year. For a kid from Selma, playing on The Plains was the dream. He signed his National Letter of Intent and was all set to follow in the footsteps of guys like Casey Mize.

Then the 2019 MLB Draft happened.
The Orioles took him with the first pick of the second round (42nd overall). Because he was such a high-ceiling talent with a strong commitment to college, Baltimore had to open the checkbook. They eventually convinced him to bypass Auburn with an over-slot signing bonus of $2.3 million.
It’s funny to think about now, but there was a legitimate debate among scouts about whether he’d stick at shortstop. His frame was already filling out—he was about 6-foot-3 and 200 pounds by graduation—and many thought he’d eventually move to third base. While he plays plenty of third now, he proved the doubters wrong by maintaining the range to handle short at an elite level.
Why Selma Was the Perfect Testing Ground
Selma isn't exactly a massive scouting hotbed like Miami or Southern California. Playing for a smaller school like Morgan Academy meant Gunnar had to work twice as hard to get noticed by national scouts.
He didn't just rely on his natural gifts. He was a 4.05 GPA student. He spent his free time volunteering at local food banks and coaching youth baseball. That "exemplary character" tag you see on his Gatorade Player of the Year profile? That wasn't just PR fluff. It’s the same maturity that allowed him to handle a mid-season slump in his rookie year without spiraling.

People often ask if the competition level in Alabama private schools prepared him for the pros. The answer is in the swing. Gunnar spent his summers with The Prospect Lab (TPL) and played in the Under Armour All-America Game and the Perfect Game All-American Classic. He was consistently testing himself against the best arms in the country, proving that the Selma stats weren't just a product of "beating up on small-school pitching."
Actionable Insights for Aspiring Players
If you're a high school athlete looking at Gunnar Henderson’s path, there are three things you should take away from his time at Morgan Academy:
- Don't specialize too early. Gunnar’s basketball background gave him the footwork and conditioning that many "baseball-only" players lack.
- Character is a scouting tool. The Orioles didn't just buy his bat; they bought his leadership. Being a 4.0 student and a community leader makes you a "safer" investment for a franchise.
- Bet on your development. Gunnar was a "projectable" athlete, meaning he had a frame that scouts knew would get stronger. Focus on your movements and athleticism, not just your current stats.
Gunnar Henderson's high school career wasn't just a prelude to the big leagues; it was the blueprint. He arrived in Baltimore as a finished product in terms of work ethic, even if his swing still needed a few MiLB tweaks.
If you want to see the future of the sport, you have to understand the kid from Selma who refused to be put in a box. He wasn't just a shortstop or a power hitter. He was the best athlete in the room, regardless of what room he was in.
