ProNine OLA Official League Baseballs - Dozen

The ProNine OLA is the durable value pick of the adult line: a precision low seam game baseball with a full grain leather cover, cushioned cork center, and premium wool blend windings. Leagues and programs that order baseballs by the case pick the OLA because it keeps game-ball construction at a price that survives a full season's budget. Sold by the dozen.

Durability That Stretches a Budget

The OLA keeps the same cushioned cork center and premium wool blend windings as ProNine's most popular game ball and wraps them in tough standard full grain leather. That combination takes doubleheaders, scrimmages, and live batting practice without going lopsided or dead.

Low Seam Standard

The precision low seam matches adult and college play. If your league or program prefers a raised seam for grip and development work, the OLA-R is this exact ball with a raised seam.

Where It Fits in the ProNine Adult Line

The OLA sits between the premium-leather OL and the economy OL1. Its raised seam twin is the OLA-R.

How It Compares to Other Brands

By model number, the OLA compares directly to the Rawlings ROLB, the Wilson A1020, and the Diamond DOL-A.

What is the difference between OLA and OLA-R?

Seam only. Same leather, same cushioned cork center, same windings; the OLA-R carries a raised seam, this OLA a low seam.

Can it double as a practice ball?

Yes, and many programs use it exactly that way: a game-legal ball tough enough for the practice bucket.
