Ronnie O'Sullivan
Ronnie O'Sullivan was again in fine form with two century breaks in a 5-2 win over Jak Jones at the Xi'an Grand Prix.
The seven-time world champion, who has impressed in his first tournament since August, will play Gary Wilson in the quarter-finals.
Jones made a 140 to stay in the match, but O'Sullivan - who hit a best of 135 in the second frame - responded with an 81 break to seal the success.
The 49-year-old was a beaten semi-finalist in the first Xi'an Grand Prix last year.
Earlier, world number two and defending champion Kyren Wilson was whitewashed 5-0 by Shaun Murphy, who hit a high of 141 in his three centuries.
The 2024 world champion scored just six points in the whole match against the relentless Murphy, who made 533 in a row.
Murphy, a Crucible champion himself in 2005, will now face Ding Junhui in the last eight.
"That's pretty much as good as I've ever played," said the 43-year-old Englishman. "That's one of the best best-of-nine matches that I've ever been part of.
"It's mad. You play so many matches around the world throughout your life and every now and then it comes together."
