Match Notes:

 Mark Allen fires in a ton and he's whistled through the next frame with another century to be the first man through to the quarter finals.

 Allen keeps the momentum going to lead 11-5 after the second session.

 Allen is embarking on a 147 attempt. This time he hasn't taken a pink and is on 72... and he's lost position and he's overcut the black from near the bualk line!

 Allen wins three of the first four frames to lead 8-4. Davis needs to do something, and quickly.

 Allen starts the second session brightly to open up a 6-3 lead.

 Davis takes the last of the afternoon to trail 5-3.

 He's done it. The first 146 in Crucible history.

 Mark Allen is on course, at the moment, for a 146 in frame six. We've never had a 146 at the Crucible. He's on the yellow now and still on course. A shame he couldn't win £146,000 for a 146.

Allen levels at 2-2 at the interval, a pretty brisk match so far.

 Mark Allen sparks into life with a 81 break.

 Allen hasn't got going at all yet and Davis leads 2-0.

 A good start for Mark Davis in his first Last 16 match since 1995.

 Good afternoon and welcome to Round Two...
