Big changes are apparently in store for Wilson Racquet Sports.
The sporting goods behemoth, based in Chicago has been front and center with programs to grow tennis in the U.S. and around the world.
Reliable sources say Jon Muir, General Manager of Wilson Racquet Sports is out.
Muir has been with Wilson since 1997 when he started as a territory manager. He moved up the ranks, and in 2006, he was named worldwide general manager for Wilson Racquet Sports. He has been the face of Wilson Racquet Sports around the world.
Also out is Jeff Adams, who has been Wilson's National Sales manager.
It is not certain if any other changes will be announced, or when Wilson will confirm these changes.
Among the top tennis professionals playing with a Wilson racquet are Roger Federer, Serena and Venus Williams, Victoria Azarenka, and Kei Nishikori.
Wilson, a leading producer of equipment in racquet sports for years, has made it a priority to grow the sport of tennis at the grass roots level by getting a racquet, particularly a Wilson tennis racquet in every kid's hand. One place this is happening is through TGA Premier Youth Tennis' popular school-based model. Wilson has also been on board with the USTA's "10 and Under Tennis" initiatives.
