O'Sullivan was beaten by Quinten Hann
|
Ronnie O'Sullivan has been knocked out in the third round in Las Vegas on his debut appearance on the lucrative International Pool Tour.
"The Rocket" won only one of his four third-round matches at the North American Open 8-ball Pool Open.
He beat fellow-Brit Karl Boyes 8-5 but lost 8-4 to former snooker player Quinten Hann of Australia.
O'Sullivan was also beaten 8-6 by Filipino player Francisco Bustamante and 8-7 by America's Corey Deuel.
The results left O'Sullivan bottom of his group and with the lowest games-won percentage.
O'Sullivan had earlier won two of his five second-round matches.
But although he tied with two other players in his group, he advanced due to his higher games-won percentage.
O'Sullivan beat Shannon Daulton 8-4 and Tom Storm 8-6 but lost 8-6 to fellow Brit Robert McKenna, 8-3 to Johnny Archer and 8-7 to Mika Immonen.
In the first round, O'Sullivan finished third out of five, progressing after winning his final contest.
He lost 8-6 to American Dennis Hatch and 8-6 to Hungarian Sandor Tot but beat American Mike Lebron 8-2 and Frenchman Vincent Facquet 8-5.
The International Pool Tour also includes a stop at London's Excel Centre in October.
