World number two Andy Murray overcame fellow Briton Kyle Edmund 7-6 (11-9) 6-2 to make the China Open semi-finals.
Murray, 29, came through an even first set via a tie-break, but found himself a break down early in the second.
But Edmund, who will rise into the top 50 after beating Spaniard Roberto Bautista Agut to make the least eight, then lost three straight service games to allow his compatriot through.
Murray will face Spain’s David Ferrer in the last four.
It was a heartening performance from Edmund, who hung tough with Murray in the first set despite failing to win a single point off the Scot’s first serve.
The 21-year-old Yorkshireman, who was ranked outside the top 100 in February, was edged out in the tie-break and then ran out of steam after a promising start to the second.
Murray has lost just once in 11 Tour level meetings with other Britons, going down in straight sets to Tim Henman in Bangkok in September 2006. He beat Edmund at the Aegon Championships quarter-finals at Queen’s earlier this year in their only previous meeting.
On the other side of the draw second seed Rafael Nadal meets Bulgarian Grigor Dimitrov in one quarter-final while Wimbledon finalist Milos Raonic playing Spain’s Pablo Carreno Busta in the other.
