Mark Williams progressed to the quarter-finals of World Snooker Championship with an impressive 13-7 win over John Higgins.
In a repeat of the 2018 decider, Williams, with a 10-6 overnight lead closed out the match with breaks of 76, 85 and 77. At 10-3, Higgins did miss the black at 113 when going for a 147, but it started a rally that saw the four-time champion cut the deficit.
However, Welshman Williams regained the initiative in the final session and his solid break-building saw him over the line. He will play either Mark Allen Mark Selby in the last eight.
Neil Robertson said he has carried forward his momentum from a successful Tour Championship after he beat Jack Lisowski to reach the quarters.
The Australian, leading 9-7 overnight, produced breaks of 126, 87 and 70 as he wrapped up a 13-9 second round victory.
Robertson has only reached the semi-finals once since winning his only world title in 2010 - but he has looked in good form in Sheffield this year.
"The tour championship was certainly the best I've ever performed in an event, certainly from start to finish," he said.
"I've kept that momentum going into the first two rounds here, but the form and results don't really matter - it's all about what I do in my next match.
"I've got to forget about playing well or anything and just prepare as well as I have done."
On the match itself, the 39-year-old said: "Yesterday was an awesome session of snooker, I think we both had four frame-winning visits each in the eight frames and so coming into tonight (this morning) I felt really good.
"I thought he had thrown just about everything at me that he could possibly throw at me and then today I kept that going again, had a little bit of luck today...which was nice."
