The 2025 Miken Ultra Gamer Series Johnny Bailey Endloaded SSUSA Slow Pitch Softball Bat (MSS5JBL) is the ultimate power tool for senior players looking to dominate the diamond with every swing. Part of the Ultra Gamer Series, this Johnny Bailey Signature Model is built for those who swing big, swing fast, and swing with purpose. Designed with a 12-inch barrel and .5 oz Maxload endload, it delivers the kind of explosive pop and distance that can change the game with one swing.
At the core of this bat is Miken’s E-Flex 360+ barrel technology, enhanced with C-4 premium carbon fiber and a proprietary resin system, creating 10% more barrel flex than previous models. The result? A barrel that maximizes trampoline effect and forgiveness, giving you elite performance across a wider hitting surface. The optimized angle layup ensures you’re getting maximum responsiveness, even on slight mis-hits.
The Super Flex Handle pairs perfectly with the barrel tech, providing optimal whip through the zone and superior energy transfer for scorching-hot exit velocities. The A1 Knob adds comfort and control, making this two-piece composite bat not just powerful—but smooth and consistent swing after swing. With no warranty and SSUSA/ISA certification, this bat is built for serious players who are ready to trust their gear and let it rip.
If you're ready to make a statement in your senior league, the 2025 Miken Ultra Gamer Series Johnny Bailey Bat is your ticket to launching moonshots, owning the box, and playing with championship-level confidence. Available in 25oz, 26oz, 27oz, and 28oz—grab yours and let the bombs begin.

OPTION GUIDE: Should I order this bat stock/untouched or Heat Rolled with Progressive Pressure?
If you order your new bat Heat Rolled with Progressive Pressure, it will be delivered to you completely and evenly broken in. This process adds 20-40ft of distance to your solid hits, increases consistency, improves durability and adds 2-3 business days of lead time to your order. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use. We (LongballBats.com) do not encourage the use of a Heat Rolled bat in any game or event where it is against the rules. Click here for details about our process!
