Shaun Murphy overcame illness to book his place in the quarter-finals of the Saga Insurance Masters at Wembley. The 2005 world champion fought back from 2-0 down to emerge as a deserved 6-3 winner against Ali Carter in their last-16 duel.

Afterwards Murphy revealed that he had struggled badly with a stomach bug during the match. "I've not been very well. I was going to the toilet every 20 minutes over new year," said Murphy.

"I'm still not very well. Ali was poorly through the match as well. He said he wasn't feeling very well, so we both struggled. But I hope over the next few days I can get better and do well here. This tournament has such a great heritage that I'd love make my mark on the trophy."

Carter had won the opening frame on the final black and edged two frames ahead after winning a scrappy second frame 71-29. But Murphy responded with a break of 66 - and he levelled the match before the interval by winning the fourth frame 72-1.

Carter then took the first frame after the resumption thanks to a break of 77, only for Murphy to square the match again with a run of 73. From there, Murphy raised his game to ensure a quarter-final meeting with either Ken Doherty or Mark Williams on Tuesday.

"I've had the flu, which hasn't helped," said Carter. "Shaun played well, but not great. It was a workmanlike performance, but nothing special."
