The private equity owner of Rawlings Sporting Goods Co., one of the oldest makers of baseball apparel and equipment, is exploring the sale of its stake in the company in an effort to tap booming investor demand for sports-related investments.

Seidler Equity acquired the 139-Year-Old gear maker several years ago. The potential sale comes as valuations for sports assets surge, driven by media rights deals and growing fan engagement.

Rawlings Sporting Goods Co. supplies gloves, helmets, and uniforms to Major League Baseball and amateur leagues worldwide. A transaction could value the business at a significant premium, reflecting the scarcity of pure-play sports equipment manufacturers.
