High school sports usually follow a predictable script. You have the star quarterback, the point guard with a Division I offer, and the quiet kid who hits home runs when nobody is looking. Then you meet the December twins at El Camino Real. This isn't your standard "talented siblings" narrative. It's a weird, rhythmic, and highly effective blend of high-stakes baseball and the kind of musical discipline that most athletes wouldn't touch with a ten-foot pole.
If you follow City Section baseball in Woodland Hills, you know the name. The December brothers—Justin and Jaxson—have turned El Camino Real into a fascinating case study on how diverse interests actually build better athletes. While most kids are grinding through year-round travel ball until they burn out, these two are balancing the diamond with the concert hall. It’s unconventional. It’s refreshing. Honestly, it’s exactly what’s missing from the hyper-specialized world of modern youth sports.
The Pitching Rhythm and Musical Timing
People often talk about "rhythm" on the mound, but for the December twins, that’s not a metaphor. It’s literal. One brother is a pitcher; the other is a catcher. That battery connection is already intense between siblings, but add a shared background in music, and you get a level of synchronization that’s hard to coach.
Baseball is a game of intervals. The time between pitches, the cadence of a delivery, and the split-second decision to swing all rely on an internal clock. Studies in sports psychology often point to "temporal processing" as a key factor in elite performance. When you’ve spent years reading sheet music and hitting specific notes on a beat, your brain develops a heightened sense of timing. On the mound, that translates to a repeatable delivery that doesn't falter under pressure.
Jaxson and Justin aren't just "kids who play instruments." They’re musicians who understand that a mistake in a recital is just as permanent as a hanging curveball in the bottom of the seventh. That mental toughness is a transferable skill. If you can stand in front of an audience and perform a complex piece, staring down a bases-loaded jam in a league rivalry game feels a lot more manageable.
Breaking the Myth of Single Sport Specialization
There is a toxic trend in Southern California sports right now. Parents think that if their kid isn't playing 100 games a year of a single sport, they're falling behind. The December twins prove that’s total nonsense. By dedicating time to music, they’re actually protecting their bodies and sharpening their minds in ways that a weekend tournament in Arizona never could.
- Injury Prevention: Repetitive stress is the number one killer of high school pitching arms. Taking time away from the ball to focus on music provides a "built-in" recovery period.
- Cognitive Flexibility: Learning an instrument forces the brain to create new neural pathways. This makes for "smarter" players who can adjust to a pitcher's sequence or a coach's tactical shift mid-game.
- Emotional Balance: When baseball is your entire identity, a slump feels like the end of the world. For these twins, if they have a rough day at the plate, they still have their music. That perspective keeps them grounded.
The El Camino Real program has a long history of excellence, but the December brothers represent a different kind of "Royals" tradition. They're showing that you don't have to be a one-dimensional robot to win games. Coaches at the collegiate level are increasingly looking for "multi-tooled" individuals—not just in terms of speed or power, but in terms of character and diverse interests.
The Battery Connection and Brotherly Intuition
Being a twin in sports is a massive competitive advantage. There's a shorthand language that develops. At El Camino Real, having a brother duo behind the plate and on the rubber creates a closed loop of communication. They don't need complex signs or long mound visits. They just know.
This isn't magic. It's thousands of hours spent together, both in the dugout and at home practicing their instruments. They understand each other’s tendencies, frustrations, and "tells." When Justin is struggling with his command, Jaxson knows exactly what to say—or what not to say—to get him back in the zone. Most teams spend an entire season trying to build that kind of chemistry. These two had it before they even put on the jersey.
The City Section is notoriously tough. You’re playing against schools with massive budgets and players who have been groomed for the pros since they were five. To compete, you need an edge. For the December twins, that edge is their ability to switch gears. They can go from the precision of a musical performance to the raw intensity of a conference playoff game without blinking.
What Coaches Can Learn from the December Duo
If you're a coach or a parent, there's a big takeaway here. Stop forcing kids to choose. The obsession with specialization is creating a generation of burnt-out athletes who lack hobbies, interests, or personality. The December brothers are thriving because they are allowed to be whole people.
We see this at the professional level too. Look at players like Mookie Betts, an elite bowler, or various MLB players who are accomplished musicians. Those outside interests aren't distractions. They are the "secret sauce" that prevents the grind of a 162-game season from becoming a soul-crushing chore.
El Camino Real is lucky to have them, but the broader sports community is lucky to have their example. We need more kids who are comfortable carrying a trumpet case and a bat bag at the same time. It makes the game more interesting, and it makes the players better humans.
How to Apply the December Method to Your Own Training
If you want to replicate the success of the December twins, you have to embrace the "off-ramp" strategy. You can't be at 100% intensity in your primary sport 365 days a year.
- Find a "Contrast Hobby": If your sport is loud and physical, find something quiet and technical, like music or coding.
- Focus on Hand-Eye Coordination: Both music and baseball rely on the connection between the eyes, the brain, and the fingers. Activities like piano or guitar are essentially high-level agility training for your hands.
- Prioritize Mental Recovery: Use your secondary interest as a way to "clear the cache" of your brain after a stressful game.
- Embrace Being Different: Don't worry about being the "music kid" on the team. Being well-rounded is a superpower, not a weakness.
The December twins are going to keep winning games for El Camino Real. They’re going to keep playing their music. And while other players are burning out by senior year, these two will likely be hitting their stride, thanks to a lifestyle that values harmony as much as heat on a fastball. Keep an eye on the box scores, but don't be surprised if you see their names on a concert program too. That’s just how they roll.
