The “MR-1 Senior” Juno's second senior signature bat for Willie Allen & Patrick Riporti features our brand-new PAN-M35J technology.
The "MR-1 Senior" is designed for SENIOR PLAY. A 12.5" barrel combined with our ergonomic Ultra-Thin Handle allows for a smooth swing with an extreme amount of performance. The UTH45 handle is among the stiffest handles allowing for extreme precision through the swing plane with minimal to no flex.
Offered with a 12.5" barrel in 3 different weights (25, 26, or 27 ounce) and 5 different end load distributions from you to choose from: Balanced, 1/4oz end load, 1/2oz end load, 3/4oz end load, and a full 1oz end load. The end load is added on top of the natural bat weight (i.e. 26 with 1/2oz end load will weigh ~26.5oz).
These senior bats are manufactured and certified to meet the Senior Softball (SSUSA) bat testing standards.

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!
