Insperity Invitational
The Insperity Invitational is a professional golf tournament held in Greater Houston, Texas, United States as part of the PGA Tour Champions. It debuted in 2004 as the Administaff Small Business Classic. The first four editions were at Augusta Pines Golf Club in Spring, then it was moved to The Woodlands Country Club in The Woodlands in 2008, the former home of the Houston Open on the PGA Tour.
Played in October for its first eight years, it changed to early May in 2012. Insperity, previously known as Administaff, has been the event's main sponsor since its debut. The purse for 2018 is $2.2 million, with a winner's share of $330,000.
