What is MLBx?

At its core, MLBx is a 3-on-3 baseball format, a significant departure from the traditional nine-player structure. The condensed setup is expected to create more action, quicker innings, and a heightened emphasis on individual athleticism. This isn’t just baseball—it’s baseball reimagined.

MLBx is being described as a fast-paced format centered around power and athleticism. With fewer players on the field, the game naturally opens up, placing a premium on versatility, quick reactions, and explosive playmaking. Think less downtime, more highlight-reel moments.

This format could also encourage creative strategies, as teams adapt to limited defensive coverage and more offensive opportunities. It’s a version of the game where speed, strength, and instinct take over.

A Co-Ed, Star-Studded Experience

Perhaps the most groundbreaking aspect of MLBx is its co-ed team structure. Teams will feature a mix of male and female athletes competing side by side, an exciting step forward in showcasing talent across the sport.

But that’s not all. MLBx rosters are expected to include:

• Current and former MLB players
• Legends of the game
• Celebrities
• Special guest athletes

This blend of personalities adds an entertainment factor that goes beyond competition, creating an event that feels part sport, part showcase.
