Jamie Cope fired snooker's fourth 147 in four days on his way to the last 16 of PTC 11 in Sheffield.

Cope had the effort during his 4-3 round three victory over Kurt Maflin and also needed a 111 to take care of the Norwegian.

It was the third maximum of Cope's career and he joins Matthew Stevens and Ding Junhui (twice) in firing a maximum at the World Snooker Academy this week. He will next face UK champion Judd Trump who beat Alan McManus 4-2.

On the day that the bottom half of the PTC 11 draw played to the round of 16, Mark Selby was arguably the most impressive performer and he won all three of his matches 4-0, including a success against Mark Williams in the third round.

He will now play Graeme Dott in the last 16.
