Serena Williams gave Carla Suarez Navarro a double bagel for her birthday as the defending champion raced into the semi-finals of the US Open.
Suarez Navarro's previous record against Williams gave a hint of what was to come, with the Spaniard, who turned 25 today, having won just five games in two previous matches.
This was not nearly as close.
From the moment the American held her opening game to love, Suarez Navarro was scrambling just to win the odd point.
She managed only five in an opening set that lasted just 19 minutes.
The subdued crowd on Arthur Ashe did not know how to react and it did not get much better in the second set.
Suarez Navarro had two chances to get on the board in the second game but could not take them.
She had another opening in the fifth game as Williams momentarily struggled with the swirling wind and gave up two break points but both went begging.
It had not been a good evening for Spaniards on Flushing Meadows' centre court - Marcel Granollers had not won a game in the final two sets of the preceding match against Novak Djokovic.
Williams was every bit as dominant as her fellow top seed, and the 6-0 6-0 demolition was completed in 52 minutes.
Victoria Azarenka is missing her groove but happy to be finding a way through the tournament after another tough battle to beat Ana Ivanovic in the fourth round.
The second seed came into the US Open on the back of a victory over Serena Williams in the final in Cincinnati but has struggled to find her best form in New York.
In the third round she lost the first set to France's Alize Cornet before fighting back, and it was the same story against Ivanovic as she ground out a 4-6 6-3 6-4 victory after two hours and 10 minutes.
Azarenka said: "I think it's a process. You start a tournament a certain way and you find the ways how to make it better. From every round it gets tougher and tougher.
"So I don't expect or I never search for the feeling that I had maybe in Cincinnati or at the Australian Open or two years ago. It's not going to feel the same way."
The match had been due to be played on Monday but, to the bemusement of many, it was cancelled because of a lengthy rain delay, even though all the other singles matches were completed on schedule.
That could potentially put Azarenka at a disadvantage, with her quarter-final opponent Daniela Hantuchova having a day extra to prepare.
The Belarusian had no complaints, though, saying: "Mother Nature could have done something. She was crying yesterday, so there's nothing I could have done."
Sixth seed Li Na was also given a real battle by Ekaterina Makarova but pulled away in the deciding set to reach her first Flushing Meadows semi-final.
Big-hitting Russian left-hander Makarova had knocked out third seed Agnieszka Radwanska in the previous round and she recovered from 4-2 down in the second set tie-break to level the match.
But Li, a former French Open winner and two-time Australian Open finalist, has been in impressive form this tournament and she came through 6-4 6-7 (5/7) 6-2 to set up a probable clash with Williams in the last four.
