Song upsets Pinches

The world number 57 had overcome Ronnie O'Sullivan to win the knockout event on Tuesday, but his form deserted him as he was humbled 3-1 in the second qualifying round.

Liu, who reached the Grand Prix quarter-finals after qualifying courtesy of John Higgins's suspension, finished off his first-round match in the morning before turning his attention to Pinches.

He compiled a 91 break on his way to a victory that sets up a third round match against Michael Holt, with the winner reaching the tournament proper in Glasgow.

Other winners included Jimmy White, who beat Michael Judge 3-0, and Bjorn Haneveer who upset Joe Swail 3-2.

Female players Wendy Jans and Anita Rizzuti both lost in the first qualifying round.

The second qualifying round continues on Monday.
