China’s Yan Bingtao was forced to dig deep to stay in the World Snooker Championship after the second session of his last-16 clash against Shaun Murphy, but will need a Herculean effort to progress in Sheffield on Monday. The 21-year-old went into day two of the match trailing 2-6 and after sharing the frames in the second session remains four adrift of the 2005 world champion at 6-10 in their best of 25 clash. The match will be played to a conclusion on Monday night, (from 2am on Tuesday, Hong Kong time). As he did in the opening session, “The Magician” Murphy was off to a quick start on Sunday guiding in breaks of 88 and 68 on his way to a commanding 8-2 lead over the Shandong native. But Yan again dug in and took frames 11 and 12 with clearances of 100, 50 and 64. The pair exchanged the final four frames of the day’s action after the midsession break, with Yan again taking the last frame of the day, to take the match to a final session at the Crucible. Ding Junhui crashes out of World Snooker Championships Masters champion Yan will need to be at his best to overhaul triple crown winner Murphy, who looks in good nick at this year’s showpiece. Another fast start from him in the final session of the match will see China’s interest in this year’s Championship ended prematurely. Elsewhere on Sunday, Mark Selby grabbed a 9-6 advantage against Mark Allen in their second round match, and world No 1 Judd Trump is in touching distance of a quarter-final spot leading Dave Gilbert 11-5. Stuart Bingham leads fellow qualifier Jamie Jones of Wales 10-6.
