LONDON - China's hopeful Yan Bingtao set up a clash with world number one Judd Trump as the 20-year-old reached the last 16 stage at the Snooker World Championship by beating Elliot Slessor 10-7 on Monday.

Judd Trump came from 5-2 down to knock out qualifier Tom Ford 10-8 last Friday

Yan dominated Sunday's first session 7-1 but met strong challenges from Slessor, who took five frames in a row to trail in 9-7. But Yan managed to win the 17th game to pass the opening round of the tournament for the first time.

The world number 16 will meet reigning world champion Trump, who came from 5-2 down to knock out qualifier Tom Ford 10-8 last Friday.

Earlier, Ronnie O'Sullivan's smashed Thai player Thepchaiya Un-Nooh 10-1 in their first-round encounter, setting a new record for the fastest match at the Crucible.
