About Gamemaster

GameMaster began in 1975 as a sporting goods supplier to team dealers, sporting good chains and mass merchants. In 1983, GameMaster became one of the first licensees with CLC introducing a line of collegiate licensed inflatables. Expanding its’ licensed products, in 1999, GameMaster signed an agreement with Louisville Slugger to sell a line of baseball training items. The UPM 45 pitching machine, which is the official pitching machine for both Babe Ruth Baseball and PONY Baseball/Softball has become the number one selling pitching machine in the world.  All our Louisville Slugger Training items help improve fundamentals and make practice and the game more fun.  We are proud with our affiliations with all our Licensor’s.
