What is the official brand of baseball's used in the Major Leagues?

Rawlings is a sports equipment manufacturing company based in the United States and founded in 1887. The parent company has been Newell Brands since 2016. Rawlings specializes in baseball equipment, but also manufactures softball, basketball, training equipment and American footballs.

In 1955 Spalding bought Rawlings, and began using it to manufacture baseballs.

13 years after acquiring it, an anti-trust investigation forced Spalding to sell Rawlings again, but as it did so Spalding set up a contract that would have Rawlings manufacture baseballs to sell with the Spalding logo.

When this agreement ended in 1977, Rawlings began using its own logo, becoming the official supplier of the major leagues. Spalding had been the supplier for a century. All the balls supplied to the major and minor leagues are manufactured in Costa Rica.
