Custom Cup for a Big League Backstop: Cal Raleigh Gets the Diamond MMA Treatment

At Diamond MMA, we’re serious about groin protection. So when it comes to the guys behind the plate—those who willingly put their bodies between 100 mph fastballs and home plate—we take things very seriously. That’s why we were pumped to create a custom Diamond MMA athletic cup for Seattle Mariners catcher Cal Raleigh, a.k.a. "Big Dumper."

Cal is a fan favorite not just for his clutch hitting, but for the grit and toughness he brings to every game. As a catcher, he’s in the line of fire on every pitch—foul tips, wild bounces, and bone-jarring collisions are just part of the job. And while most fans focus on the glove work and game-calling, there’s one piece of gear that’s just as critical to his performance and protection: reliable groin protection.

Why Baseball Catchers Need Serious Groin Protection

Baseball isn’t always thought of as a contact sport—but tell that to a catcher who’s taken a foul ball to the cup. The groin area is one of the most vulnerable (and painful) places to get hit, and yet many traditional cups shift, slide, or leave athletes unprotected when it matters most.

That’s where Diamond MMA’s patented system comes in. Our athletic cup and jock system was engineered to eliminate cup shifting—locking it in place using our patented quad-strap design, even during the most intense movements. Whether you're throwing to second or blocking a curveball in the dirt, our system stays where it’s supposed to.

Cal Raleigh now has his own custom Diamond MMA cup, engraved with his number and nickname, and built with the same bulletproof-grade polycarbonate core and soft elastomer edge that’s trusted by UFC fighters, professional athletes, and the U.S. military.

Protecting the Future of Baseball

Diamond MMA is proud to support athletes at all levels—from Little League to the Big Leagues. Whether you're suiting up for your first season or you're already behind the plate in front of 40,000 fans, your groin protection shouldn’t be an afterthought. It should be bulletproof. Comfortable. Shift-proof.

Just ask Cal.
