Murphy has made rare progress to the last 16 of a world-ranking event

The world four number lost 3-5 to 22-year-old Murphy, ranked 48th, but said: "It was a bad result but nothing to get too disheartened about."

Two-time world champion Mark Williams eased into the third round with a 5-1 victory over Leicester's Joe Jogia.

Hunter followed Jimmy White, Matthew Stevens and 2002 world champion Peter Ebdon out of the event.

Full results

Murphy advances to the last 16 of a world ranking event for only the second time in his six-year professional career.

And he put his success down to his happiness off the table.

"My girlfriend Claire is a wonderful woman. We've become engaged and we're involved with a tremendous church in Rotherham," said Murphy.

To play quite well while getting a result was great for my confidence Mark Williams

"Tactics have been my downfall in the past, but I'm trying to keep things tighter. I missed a few long pots today - but if I can sort that out and knit the two together special things could happen."

Murphy raced to a 3-1 lead and then moved 4-2 ahead with a break of 69 in the sixth.

Hunter fought back with a dominant display in frame seven but the three-time Masters champion could only watch as Murphy notched up a run of 88 to set up a meeting with Graeme Dott or Michael Holt.

Williams, without a trophy since the Grand Prix 13 months ago, fired in breaks of 80, 43, 67, 72 and 51 on the way to victory in only 89 minutes.

"It was very important for me to get a result, but to play quite well doing it was great for my confidence," said Williams, who admitted to a lack of practice recently.

"The more you lose the worse you feel, but I don't mind losing as much as some. If Stephen Hendry loses he wants to throw himself off a bridge."
