Top seed Lindsay Davenport was in impressive form as she swept aside Svetlana Kuznetsova 7-6 (7-1) 6-3 on Court One to reach the semi-finals.
The first set was even, although Kuznetsova squandered a set point at 5-4 and it went to the tie-break, in which Davenport was just too good.
Kuznetsova's game fell apart for a time after that and despite a brave showing in a couple of games, she struggled.
Davenport never let her grip weaken and won with her second match point.
Davenport showed her intentions right from the start, breaking in the very first game, and although Kuznetsova levelled the match at 2-2, the Russian could not capitalise.
She wasted the chance to win the set when she missed the backhand and both players lost their serve again before the match went to the tie-break.
Davenport upped a gear then to rattle through it and suddenly the pattern of the match changed.
The American totally dominated her opponent in the early stages of the second set and it was this period of play that decided the contest.
Kuznetsova showed sheer grit and determination to recover from 40-0 down to win the fourth game and stay in the match and performed a similar recovery in her next service game.
But it was only a matter of time before Davenport secured victory, which she did in an hour and 15 minutes to earn a semi-final against third seed Amelie Mauresmo.
Afterwards Davenport said retirement was no longer on her mind.
"I believed what I said and was looking forward to doing some different things but opening my big mouth I started to play a lot better," she said.
"Now it's so far from my mind that I can't even think of stopping."
She added: "I have never played Amelie on grass but it seems like she is playing great. Amelie is a great athlete and I admire her a lot.
"It will be fascinating and I will have to mix up the pace, use a lot of slices and a lot of different kind of shots that I used to focus on.
"But I'm delighted to get through and I just want to focus on this win now."
