World number one Mark Selby beat Ryan Day 5-3 to set up a semi-final clash against Stuart Bingham in the Shanghai Masters on Saturday.
Selby took an early lead and remained ahead of Day throughout their quarter-final, despite the Welsh potter having a chance to level the game in the eighth frame.
Bingham, the 2014 Shanghai Masters champion and current world number two, had an easier day in dispatching Ali Carter 5-1, which included a break of 91.
Speaking to www.worldsnooker.com, Bingham said: "I'm over the moon to be in the semi-finals.
"It's great to play the world number one and reigning world champion. It's always a good occasion."
Home favourite Ding Junhui beat Michael Holt 5-3 and will face Stephen Maguire in the other last-four encounter after the Scot eased past Michael White 5-1.
