Ronnie O'Sullivan in command; Mark Williams stages stunning semi-final fightback

Both semi-finals are set-up for a fascinating conclusion, with Mark Williams finally finding his brilliant best.

Mark Williams staged a stunning fightback in the snooker World Championships semi-final against Judd Trump.

The Welsh Potting Machine was 11-5 going into the night session in the first-to 17 match.

However, he was close to his brilliant best to reduce his arrears to just two frames.

At the close of play, Trump still led the match but there had been a monumental momentum shift in the Welshman's favour with the scores at 13-11.

Williams looked like he was in for another tough session when Trump rattled off a 120 to win the first frame of the night.

However, Williams quickly found his groove he made four half-centuries and a stunning 137 break to win five frames on the spin.

Trump finally responded with a 113 of his own, but Williams toom the last frame of the session to set up a thrilling finale.

Speaking about Williams' comeback, 1997 world champion Ken Doherty told BBC Sport: "What a performance. The match between Judd Trump and Mark Williams is back on.

"Mark has something that is innate in all great champions. He believed in his technique and composure and showed a lot of character.

"He [Mark Williams] is one of the greatest players that has ever played this game. He did not want to give it to Judd easily and he potted some great balls."

Earlier in the day, Ronnie O'Sullivan took total command of the other semi-final, building a 10-6 lead of fellow class of 92'er John Higgins.

The session started with the players exchanging blows, but O'Sullivan eventually wrestled control after the mid-session interval.

The highlight came in the final frame, when O'Sullivan potted two reds, two blacks and all the colours to force a re-spotted black, which he won to land a potentially blow.
