Ronnie O'Sullivan and Paul Hunter both dazzled with whitewash victories in Preston tonight to set up a semi-final meeting at the Totesport Grand Prix.

It took O'Sullivan just one hour and 11 minutes to destroy Mark Selby 5-0 in his quarter-final, and Hunter was only eight minutes slower as he trounced Thailand's James Wattana.

Ominously for Hunter, title rival O'Sullivan produced his best performance of the week.

His fourth win included two breaks of 135, plus further runs of 62 and 76.

"I managed to get off to a good start and kept it going,"  said the world number one and world champion.

"My safety was good, so was my thinking, and so too was my break-building. It's as well as I have played in the tournament."

Overall, O'Sullivan outscored his 21-year-old Leicester opponent by 522 points to 46.

O'Sullivan is now just two wins away from clinching the last remaining major trophy missing from his collection.

World number four Hunter has not even featured in a Grand Prix final but he is now in the mood to put the record straight.

"I didn't feel as if I cued as well as I did against Steve Davis in the last round but it's always nice to win 5-0,"  said the Leeds player.

The 26-year-old Yorkshireman will be seeking a third successive win against O'Sullivan tomorrow night.

Contesting tomorrow's other semi-final will be Dublin's Michael Judge and Preston's own Ian McCulloch, both keen for a chance to tackle O'Sullivan or Hunter in Sunday's best-of-17-frames final.
