China's Ding Junhui reached the second round of the World Championship on Tuesday despite embarrassingly squandering an opportunity to record a maximum 147 break.

Trailing 5-3 to Mark Davis at Sheffield's Crucible Theatre, Ding was on a break of 96 when he screwed back for the blue ball instead of setting himself up to pot the black.

The miscalculation drew gasps from the audience, while Ding put his head in his hands, but he soon regained his composure and went on to complete a 10-7 victory.

In the day's other match, Mark Allen established a 6-3 lead over Ryan Day ahead of the resumption of play later on Tuesday.
