Judd Trump looked close to the form which won him a hat-trick of ranking titles in October as he trounced Mark Selby 5-1 to reach the semi-finals of the Spreadex World Grand Prix.

Playing on home turf in Leicester, Selby suffered a resounding defeat as Trump stormed through to a meeting on Friday evening with Cao Yupeng, who came from 4-2 down to beat Mark Williams 5-4.
After the match, Bristol's Trump reacted to the announcement of the first ever WST event in Saudi Arabia, describing it as "amazing for snooker."
Trump has lost just three frames in three matches so far this week and is two wins away from a fourth trophy of the season, having landed the English Open, Wuhan Open and Northern Ireland Open. The 34-year-old is through to his 59th ranking event semi-final.
A break of 59 helped Trump win the opening frame, then Selby had a chance to level, but missed the final yellow to a baulk corner in frame two and his opponent took advantage. Trump also dominated the third then made a 119 for 4-0. After the interval, Selby at least avoided the whitewash thanks to a run of 100, but Trump soon wrapped up the contest with a 68 in frame six.
"Mark struggled bit, but any time you beat him you have to be happy," said Trump, who is the only player to win this event three times. "I have had a good record against him recently and I feel comfortable against him. I tried to attack so that the game didn't get bogged down.
"My results this week have been good although I still don't feel I have played that well. When I have missed, my opponents haven't punished me. I'm really happy to be in another semi-final and the tournament really starts now for me. I had a great first half of the season, it would be really hard to keep that going for the whole season, so to win the event this week would be important."
Asked about the new Riyadh Season World Masters of Snooker, to take place in March, the world number two added: "It's amazing for snooker to be going to different places. We got back to China this season and felt appreciated. We are expanding and going to new territories. It's amazing that Saudi Arabia want to get involved."
China's Cao is through to the fifth ranking event semi-final of his career, and second of the season having finished runner-up to Mark Allen at the Shoot Out last month. The 33-year-old scored one of his best ever wins against Williams tonight to keep alive his hopes of a first title.
Three-time Crucible king Williams eased into a 3-0 lead with top breaks of 92 and 60, and later led 4-2 before world number 43 Cao hit back with 74 and 55 for 4-4. In the decider, Williams was among the balls and leading 33-5 when he suffered a cruel slice of misfortune, going into the pack of reds only to stick to the apex ball, leaving him without a pot. He later botched a safety, gifting Cao the opportunity to make an excellent 74 clearance.
"I felt quite calm when behind and during the last frame, like I didn't really mind losing the match," said Cao. "I did show some resilience today. I wasn't playing well at the beginning, especially in the first three frames. I had easy opportunities in all three but didn't manage to make a break. I just did my best to make sure of the potting later on in the match."
