China Championship: Allen clinches final-frame win over Selby

Northern Ireland's Mark Allen held his nerve to beat world number one Mark Selby 6-5 in the China Championship quarter-finals in Guangzhou.

The Antrim player hit breaks of 114, 100 and 131 on his way to taking a 5-2 lead over the world champion.

Selby fought back to level, but Allen compiled a decisive 60 break in the final frame to overcome the Englishman.

Allen, who is ranked 10th, will now face four-time world champion John Higgins in the semi-finals.

Allen progressed to the last-eight stage thanks to a 6-4 victory over Ricky Walden in the first round.
