ProNine Senior Little League Baseballs – Regular Season – Dozen

The ProNine SLL1 is a regular-season game baseball stamped with the Senior Little League logo and built for exactly what its season demands. Senior Little League brings teenage players onto the big diamond, where game balls take real punishment. A precision raised seam, full grain leather cover, cork and rubber center, and wool blend windings give it real game-ball construction at a regular-season price, and it meets all COR and compression requirements. Sold by the dozen.

Stamped for Senior Little League Play

Every ball carries the Senior Little League logo stamp leagues look for, along with COR and compression compliance. Coaches can fill the game bag and the umpire’s pregame check takes care of itself.

Construction That Handles a Season

The full grain leather cover grips well and breaks in fast, while the cork and rubber center shrugs off the repeated impacts of youth baseball, including all the practice swings these dozens inevitably absorb. Wool blend windings keep the response consistent from March to the last game of the schedule.

Regular Season or Tournament Ball?

ProNine makes this league ball in two grades. This SLL1 is the regular-season (RS) ball. The Senior Little League tournament ball upgrades to a cushioned cork center and premium wool blend windings for post-season play, when every at-bat counts a little more. Many leagues run RS balls all season and switch to the tournament grade for playoffs.

Who This Baseball Is For

Senior Little League programs, team parents splitting a case, and coaches stocking the equipment room for a full regular season of baseball. If your league plays under a different sanction, the full game baseballs collection covers every league ProNine stamps.

Is this ball approved for Senior Little League games?

It is stamped with the Senior Little League logo and meets all COR and compression requirements. Local leagues set their own ball rules, so check yours if it designates specific models.

What is the difference between this and the tournament version?

The interior. The tournament grade uses a cushioned cork center and premium wool blend windings; this RS ball uses a cork and rubber center tuned for season-long durability at a lower price.

Can we practice with them too?

Yes. The durable center construction is exactly why RS balls double as practice inventory in most programs.
