Thailand's Noppon Saengkham upset John Higgins to book a place in stage two of snooker's Championship League, recording three wins from his Group Nine matches at the Morningside Arena in Leicester.

He joins Ken Doherty, who yesterday eased into stage two as he also went unbeaten in his three matches.

Saengkham, the world number 44, beat four-time world champion Higgins 3-1 in the final game of Tuesday's evening session, making breaks of 108 and 114, to progress.

Higgins had earlier reeled off 3-0 wins over Iran's Soheil Vahedi and Brazilian Igor Figueiredo, making a clearance of 130, but came up short in the deciding fixture.

In Group 26, Chinese player Cao Yupeng marked his return to the main tour for the first time since the end of a suspension for match-fixing with three victories to also move on to winners' week.

Having now served his ban, reduced from eight years to six after pleading guilty, with three-and-a-half years of the term suspended, Cao came through the Chinese Billiards and Snooker Association qualifiers in Beijing.

The 30-year-old impressed with 3-0 wins over both Steven Hallworth and Gary Wilson, the world number 33, before also then dispatching James Cahill 3-1.
