Top seed Amelie Mauresmo booked a Wimbledon semi-final against Maria Sharapova with a 6-1 3-6 6-3 win over a misfiring Anastasia Myskina.
Mauresmo has reached the semis on her last four visits to SW19
Mauresmo cruised through the first set, with Myskina managing just one winner.
The ninth seed contributed only two in the second set but was grateful for a host of unforced errors from Mauresmo.
The match improved in the decider, but Myskina faltered at 2-3 and Mauresmo held her nerve to ensure the top four seeds will contest the semi-finals.
Mauresmo, infamous for squandering winning positions, looked in trouble again after waltzing through the opening set.
I'm not happy but I won and that's the most important thing
The 26-year-old committed 17 unforced errors to allow Myskina, who had been looking at her support camp with increasing desperation, a lifeline.
However, after a strong start by both players in the decider, it was Myskina who cracked, throwing in a double fault in a loose game to give Mauresmo a 4-2 lead.
The Frenchwoman netted a fairly routine volley on her first match point at 5-2 but shrugged off that setback to serve out victory in the next game.
"I'm a little bit relieved," admitted Mauresmo, who has reached the semi-finals on her last four visits to Wimbledon but has never gone beyond that stage.
"I'm not happy with the way it went in the second and third but I came back and won and that's the most important thing.
"I felt comfortable in the first set but I suddenly started not going forward as much and she came back.
"I have the opportunity to play better in the semis on Thursday and I will have to be avoid those kind of errors."
