The 2025 Miken Ultra Gamer Series Mike Macenko SSUSA Senior Slow Pitch Softball Bat (MSS5MMX) is a tribute to one of the greatest power hitters the game has ever seen—The Big Cat, Mike Macenko. Designed for senior sluggers who want to unleash game-changing power, this bat is engineered with elite technology and bold intent. Featuring a 13.5-inch barrel and a signature 1oz Big Cat Endload, the Macenko model delivers devastating mass through the hitting zone while still providing enough balance for smooth, explosive swings.
At the heart of this powerhouse is Miken’s E-Flex 360+ barrel technology, utilizing premium C-4 carbon fiber and an advanced resin system that increases barrel flex by 10% over previous models. The result? More trampoline, a bigger sweet spot, and higher exit velocities on every swing. Whether you're driving it deep into the gaps or looking to send one over the fence, the optimized barrel layup ensures you're getting top-tier performance with maximum consistency.
The Super Flex Handle pairs perfectly with the power-focused barrel, providing efficient energy transfer while maintaining a fluid swing path. Combined with the A1 knob and two-piece composite frame, this bat delivers a feel that's responsive, comfortable, and built to perform. The 1oz endload adds just the right amount of weight to the barrel, allowing players with strong, compact swings to fully tap into their power potential.
Finished in an aggressive red and gold colorway, and approved for SSUSA and ISA play, the 2025 Mike Macenko Ultra Gamer bat is hot out of the wrapper and built for legends. Available in multiple weights, this bat has everything you need to dominate senior slowpitch softball—because real power hitters know, it’s not just a bat—it’s a Big Cat.
