Agassi will make his return to competitive tournament tennis by participating in the Outback Champions Series event at Surprise, Ariz., in October. The tour is for players 30 and older.
Tour spokesman Randy Walker told The Associated Press on Sunday of Agassi's return. The tour plans an announcement Monday.
Agassi turns 39 next month and retired after playing in the 2006 U.S. Open. He owns eight major singles titles, including a career Grand Slam.
He's the first announced member of what will be an eight-player field competing for $150,000 in prize money at the Oct. 8-11 tournament at the Surprise Tennis and Racquet Complex.
