Wu Yize edged Shaun Murphy 6-5 in a deciding frame at the Shanghai Masters, coming from behind in the nerviest of finishes to reach the semi-finals.

The 22-year-old trailed 5-4 after squandering a 3-1 lead. He forced the decider with his fifth break of 50 or more in the match — a steady scoring run that kept him alive when Murphy looked ready to close it out.

The final frame turned on one missed red. Murphy led 62-29 and needed only to pot a red to leave Wu needing snookers (shots where the opponent has no direct route to a legal ball). He missed. Wu stepped up, cleared the table to the black, and took the frame by a single point. (BBC Sport)

This was the first meeting between the pair since May's World Championship final at the Crucible, when Wu beat Murphy 18-17 on the final black of a 35-frame marathon. The Shanghai rematch was shorter, settled over best-of-11, but the ending rhymed: Murphy in front, Wu finding a way.

Wu's reward is a semi-final against Judd Trump, who was in ruthless form. Trump whitewashed John Higgins 6-0, reeling off three consecutive century breaks (runs of 100-plus in a single visit to the table) to close out the match. He did not give Higgins a frame.

The other side of the draw produced another deciding-frame finish and another whitewash. Defending champion Kyren Wilson recovered from 5-3 down to beat Mark Williams, compiling breaks of 61, 54 and 113 across his comeback. Wilson will face Zhao Xintong in the semi-finals — a repeat of last year's last-four match, which Wilson won 10-5.

Zhao booked his place with a 6-0 demolition of Neil Robertson, his highest break a 117 in the third frame.

For the casual viewer, the story of this quarter-final day is simple: two matches went the distance, two ended with one player not winning a frame, and a 22-year-old who became world champion in May is still finding ways to win the tight ones.
