World Championships Day 14

1st semi 2nd session: Ronnie O'Sullivan 11-5 Barry Hawkins (resumes 1900)

2nd semi 2nd session: Mark Selby 9-7 Neil Robertson (resumes 10am Sat)

Mark Selby maintained a 9-7 lead over world number one Neil Robertson in the second session of their best-of-33 World Championship semi-final.

The Leicester potter led 5-3 overnight, but Robertson levelled with a 113 break, the 102nd century of his season.

Selby fought back to lead 9-6 and looked certain to extend it with a run of 53 in the 16th frame.

But he missed a simple black and the 2010 champion fired in a break of 61 to finish the session two behind.

The third session of the contest begins at 10:00 BST on Saturday.

Selby, who lost the 2007 final 18-13 to John Higgins, trails 5-4 in head-to-head matches against Robertson, but was moving closer to levelling their personal duel when he piled on the points in the final frame of the day.

Robertson looked set to start the final session 10-6 behind, but the blunder on the black allowed the Australian back in and his classy clearance to the pink sets up a tight contest going into Saturday's third and final day.

Robertson became the first player to make 100 century breaks in a season in his 13-11 win over Judd Trump in the quarter-finals. 

1st semi 3rd session: Ronnie O'Sullivan 17-7 Barry Hawkins 

Defending champion Ronnie O'Sullivan beat Barry Hawkins 17-7 with a session to spare to reach the World Championship final.

Beginning the evening six frames ahead at the Crucible, the five-time winner extended his lead with a break of 76.

Hawkins won two of the next three frames, but O'Sullivan, champion in each of the last two years, clinched four in a row to seal victory.

O'Sullivan, 38, will meet either Neil Robertson or Mark Selby in the final.

'The Rocket' punished the mistakes made by Hawkins to give himself a day off as he recorded breaks of 76, 55, 103 and 84 in the evening session.

O'Sullivan beat Shaun Murphy 13-3 in the quarter-finals and Hawkins was to fare only slightly better.

The Kent potter had started the morning trailing 6-2 after conceding the final four frames of the first session against the man who beat him in last season's final.

Although he lost the first four of the day to slip even further behind at 10-2, Hawkins finished it with a terrific 106 to close the gap to 11-5.

However, he could not maintain it in the evening and had a highest break of just 67.
