It was an ATP International Series event that was first founded as the WCT Scottsdale Open in 1986.
In 2005, The Tennis Channel purchased the tournament from IMG and moved it from Scottsdale to Las Vegas.
The move to Las Vegas was to bring a top-level tour event back to the city to fill the gap left by the Alan King Tennis Classic that ended in 1985.
It was succeeded later by a lower tier event the Las Vegas Challenger in 1997 that ran till 2000.
From 1987 to 2005 the tournament took place at the Fairmont Scottsdale Princess, where Andre Agassi was crowned champion four times.
