Ronnie O'Sullivan is in danger of dropping out of the World Championship at the second round stage, as Barry Hawkins opened up a 9-7 advantage.
The Hawk flies higher than the Rocket
Leading 5-3 overnight, Hawkins edged the first frame of the second session, despite a break of 68 from O'Sullivan. The pair then began to exchange frames as both players produced some high quality snooker. The Rocket composed breaks of 118, 82 and 89, whilst Hawkins delivered a 74 and 65.
Yet O'Sullivan gave himself the opportunity to draw level as he won the penultimate frame of the session to bring the score back to 8-7, before Hawkins rallied to win an important final frame in a tense and nervy finish. The duo play their last session on Monday evening, with the prize a quarter-final spot against world number fourteen Marco Fu.
Higgins holds his advantage in a scrappy session
Whilst one veteran champion struggled, another continued his pathway towards next weekend's final. World number eight John Higgins impressed in the first round and the opening session of the second round against Ricky Walden as he lead 6-2.
Though Higgins continued to win frames, he found it difficult to produce the kind of snooker the Crucible faithful have become accustomed to seeing from the Scotsman this week. Both Higgins and Walden managed just one half century apiece, with Higgins top scoring at 90, as they shared the session 4-4 to leave the overall score 10-6. Higgins remains favourite going into Monday evening's deciding session to see who will face Alan McManus in the last eight.
Monday's action sees the last eight line-up completed in what has already been a fascinating tournament full of twists and tales in Sheffield.
