SHEFFIELD: China’s Ding Junhui completed a 13-10 win over world number five Judd Trump to reach the quarter-finals at the World Championship in Sheffield. Ding led 10-6 going into Monday’s final session and held off a late comeback by the Englishman to win three of the seven frames played and secure victory. The Chinese player will face Welshman Mark Williams in the last eight. England’s Kyren Wilson beat Mark Allen of Northern Ireland 13-9, having begun the session with an 11-5 lead. The closest Trump came to Ding was when he scored his only century of the match to get back to 2-2 in the opening session. At the mid-session interval, Trump responded to a critical tweet by beaten qualifier Dominic Dale by calling him “clueless” after Dale had said his cue ball control was not as good as his opponent’s. But Trump, who scored two half-tons in his three-frame run to get back to 12-10, refused to blame his social media activities for his defeat: “It had nothing to do with it. It was because Ding was the better player. “It worked when I did it against Liang Wenbo [Trump’s first-round win]. People just like to pick faults.” Ding took a seemingly unassailable 12-7 lead thanks to a break of 91, but Trump made him work for the win by reeling off three frames in a row. The Bristol-based player had his chances at 12-10 as well but could not convert, and Ding finally got across the finish line to reach the quarter-finals for the fourth time.
