There was a possible £12,000 up for grabs for any player making a magic maximum, and world number eight Murphy looked set fair in the opening frame as he potted all 15 reds with blacks. But with the colours at his mercy, he missed the yellow to a baulk corner.
Murphy went on to take the next three frames with a top run of 54 and now meets Zhao Xintong in the last 32 on Saturday.

Jamie Jones shrugged off the loss of his cue to beat Rod Lawler 4-2 with runs of 121, 66, 94 and 86.
“I was on the plane yesterday with Michael White and we were sharing a sport tube (to carry their cues),” explained Welshman Jones. “Then someone came on and said Michael had to get off the plane, because he had booked it late and it was over-booked. The cue case was in his name so he had to take it off.
“So when I flew here my head was gone, to say the least. Luckily a Latvian player turned up this morning with a cue which is exactly like my old one. I was able to borrow it and I played as well as I could have done. My own cue has turned up now and I will use it in my next match so I probably won’t be able to pot a ball!”
