Serena Williams made short work of Sara Errani in the French Open quarter-finals, cruising to a 6-1 6-3 success to ease into the last four at Roland Garros.
In a repeat of the 2013 semi-final, which Williams won 6-0 6-1, the world number one was similarly dominant on Philippe Chatrier.
Errani, a runner-up here three years ago, simply could not live with the overwhelming power of the 19-time major winner.
The Italian, a career Grand-Slam winner in women's doubles, was blown away in the first set and although she showed signs of fight in the second, she never looked likely to pull off an upset.
For Williams, victory booked her place in a 27th major semi-final, as she goes in search of a third French Open crown.
Both players struggled with serve in the early stages, Williams breaking to love to earn a 2-0 lead before Errani rounded off an immediate riposte with a powerful forehand down the line.
Williams' reply was similarly swift, though, as she restored her advantage courtesy of an errant backhand from her opponent.
Errani set up another break point in the next with a beautifully angled backhand, but Williams recovered her composure to hold, before a third break from three opportunities put her 5-1 to the good.
A thumping ace down the middle sealed the set, and Williams took that momentum into the start of the second, a delicate drop shot displaying the touch to go with her power.
The set continued on serve until game seven, when Errani sent the ball long to put her opponent on the brink.
An ace on second serve in the next game left Errani serving to stay in the match, and Williams piled on the pressure in a bid to complete the job.
Uncharacteristically, the American wasted three match point opportunities - the third a glaring miss with an overhead smash into the net - but it was fourth time lucky as Errani sent a forehand into the tape as Williams advanced.
Meanwhile, Timea Bacsinszky reached her first grand slam semi-final after overcoming Alison Van Uytvanck 6-4 7-5 at the French Open on Wednesday.
The Swiss saw off fourth seed Petra Kvitova in the last 16, and she was rewarded for Wednesday's win on Suzanne Lenglen with a semi-final against world number one Williams.
Neither woman had ever been beyond the second round at Roland Garros, while Bacsinszky's third-round appearances at the Australian and US Opens were the best effort by either at any grand slam.
The unseeded Van Uytvanck, ranked 93 in the world, battled valiantly throughout, but it was 23rd seed Bacsinszky who edged into the last four following an hour and three quarters of play
