Crucible debutant Jackson Page defeated former finalist Barry Hawkins to spring a surprise on the second day of the World Snooker Championship.

On a dramatic night at the Crucible Theatre in Sheffield, 20-year-old Welshman Page knocked out England's Hawkins, the 2013 runner-up.

Page led 6-3 heading into the second session, but it was Hawkins who won the first two frames of the session to cut the gap before a miss in frame 12 was punished as Page made a 54 clearance.

Hawkins trailed 7-6 and 8-7 but was powerless as Page produced total clearances of 128 and 135 to seal victory in style 10-7.

There was another upset in the evening’s other contest as last year’s runner-up Shaun Murphy was beaten 10-8 by Stephen Maguire.

Scotland’s Maguire led 6-3 after the first session, but 2005 world champion Murphy started with a break of 130 and reduced his arrears to one at 6-5 and 7-6.

After the interval, the pair played out a 71 minute frame which England's Murphy won on the black to make the score 7-7.

It included Maguire ironically throwing his cue to the ground after missing position, Murphy inadvertently fouling the pink with his finger and a four-minute discussion over a free ball, which Murphy refused.

The frame was described by BBC commentator Ken Doherty, the 1997 world champion, as one of the craziest he had ever seen.

Murphy then took the lead for the first time at 8-7 with a break of 50, before Maguire won three in a row, including breaks of 90 and 82, to win a contest that concluded just after 11.30pm local time.

England’s Ronnie O’Sullivan secured a record-equalling 70th match victory at the Crucible as he overcame compatriot David Gilbert 10-5.

O’Sullivan led 6-3 overnight, but Gilbert won the first two frames of the afternoon with clearances from behind to reduce his deficit to one.

O’Sullivan then won four straight frames, including a century, and a good slice of fortune which saw him win frame 13 after fluking the yellow from a snooker, to seal a second-round spot.

The day’s other winner was China’s Xhao Zintong who needed less than an hour to secure a 10-2 win over Welsh qualifier Jamie Clarke.

Two breaks in the eighties helped UK champion Zintong convert his 7-2 overnight advantage into a comprehensive win.

In the day’s other matches Scotland’s Anthony McGill, a semi-finalist in 2020, opened up a 6-3 lead on England’s Liam Highfield.

Three-time world champion Mark Williams led amateur Michael White 7-2 after the first session of their all Welsh match-up.  

Williams made three centuries on his way to winning the first seven frames, before White won the lost two of the afternoon to reduce his deficit to five.
