This Miken Ultra Fusion is juiced up for Johnny Bailey! Add this Senior Slow Pitch Bat to your bag and get ready to hit 'em out just like he does!

Bat Benefits

This bat will provide that slight end loaded feel that a lot of power hitters will enjoy. However, if you have swung a balanced bat in the past and want to try your hand at a bat that has a little bit of heft to the barrel, be sure and consider this bat. It has a two-piece, all-composite design which is what most slow pitch players desire for their bat. As well, this bat will take the 3 incredible technologies of C-4 Carbon Fiber, E-Flex 360 Barrel (which is designed for maximum flex, performance, and durability) and F4P energy transfer to produce top results! Be sure to note the SSUSA (Senior Slow Pitch) certification and know that this bat is very powerful. Therefore, it won't be allowed for use in USSSA or USA (ASA) sanctioned softball events.


Due to it being Senior Certified and so high-performing, Miken does not extend any warranty period on this bat. That being said, if you wanted to get a 30 day trial on the bat from JustBats, you could do so by purchasing the bat with JustBats' Bat Assurance. Our Bat Assurance is only $30 additional!

About the Brand

During the past few years, serious softball players have looked to Miken Sports for bats that provide the highest levels of performance and durability. Our relentless focus on both technology and the demands of players has made Miken the most demanded line of softball bats today.

Although composites are the latest trend in softball bats, the technology has been the core of Miken's success since the company's inception. Miken pioneered the modern high-performance composite softball bat in 1998 and has pushed the limits with every model since. No other bat company has driven innovation as hard, and the results are indisputable. Look around. If a player is serious about softball, they are most likely swinging a Miken bat.

The success of Miken Sports has been driven by two forces - innovation and a passion for delivering what players demand. The results are obvious. Players have decided that composites are the future for bats, and no one does composite like Miken.
