CHINA’s Yu Delu recorded one of his biggest wins of his career as a surprise victory over Ronnie O’Sullivan put him through to the last eight of the PTC Grand Finals.

The 26-year-old, ranked number 48 in the world, came back from behind to beat the five-times world champion and secure a place in the quarter-finals.

O’Sullivan, who went into the match unbeaten so far in 2014, looked like winning the first frame with a break of 64 but Delu fought back to win it clearing from the final red.

The Rocket levelled before a well compiled break of 102 put Delu back in front at 2-1. But two breaks of 50 plus levelled matters again before a 140 total clearance put O’Sullivan ahead for the first time at 3-2.

But Delu came back dominating the sixth frame before a break of 57 in the all-important decider helped claim a memorable win.

Judd Trump ended Shaun Murphy’s fine form with a 4-0 win. The Bristol ace will play Joe Perry in the quarter-finals after breaks of 98 and 128 helped him to a 4-1 win over David Gilbert.

Four-times world champion John Higgins made it three major ranking quarter-finals in a row after he battled his way to a 4-2 win over Ben Woollaston.

Next for the Scot is Hong Kong’s Marco Fu who beat Mark Williams 4-2.

Despite losing the opening frame, Mark Allen was in impressive form as he beat Fergal O’Brien 4-1. Allen will take on Gerard Greene in an all Northern Ireland encounter after he edged to a 4-3 win over Anthony Hamilton.
