Roger Federer had Mikhail Youzhny in such knots as he breezed through to a Wimbledon semi-final appointment with Novak Djokovic that the Russian turned to the Royal Box for help.
Six-time champion Federer coasted to a 6-1 6-2 6-2 victory against a player he has never lost to.
This was their 14th career match and there was never any doubt the outcome would be a familiar one.
With Young royals William and Kate looking on, sitting just along from Wimbledon royalty Steffi Graf and Andre Agassi, Federer was out to impress and certainly accomplished that mission.
If the royal couple came for Andy Murray, second on Centre Court against David Ferrer, the main course would have to go a long way to trump their starter.
Indeed after Federer put away a delicious backhand drop volley to seal victory, the Royal Box led a standing ovation.
“I thought I played great out there,” Federer said. “I’m extremely happy to be back in the semi-finals here at Wimbledon.
“I think it helps when royalty shows up and other legends of the game come to see me play. I think it’s inspiring. I’m happy they came to support tennis and support me. It was very special.”
A roar of approval had greeted William and Kate as they made their entrance, followed seconds later by another for the players.
The once-customary bow to the Royal Box is no longer a Wimbledon tradition, and even from the early stages it was those in the plush seats who may have felt more like showing deference as Federer began what proved to be a masterful display.
The 30-year-old Swiss took just a minute to take the opening game to love, and broke serve in the next at the fifth time of asking.
The back injury that bothered him against Xavier Malisse was a distant memory, seemingly not an issue today.
Federer was in the mood. He swatted away a forehand impishly into the corner, with the minimum of effort, drawing gasps from the crowd.
He had many on their feet when after twice rescuing what seemed lost causes he whipped the most sumptuous of forehands across court and past Youzhny.
With the first set wrapped up in 28 minutes, play was briefly interrupted when rain began to fall.
The Centre Court roof had been left open, with organisers adamant this is an outdoor tournament, and sure enough it was a passing shower, keeping the players off for barely quarter of an hour.
On their return, the punishment continued for Youzhny who was starting to play to the crowd, screaming out after saving a pair of break points before trundling the ball into the net on the next point to slump an immediate break behind.
Federer’s dominance over Youzhny dates back to their first meeting on tour in Stockholm 12 years ago.
They played at the fourth-round stage here last year, with Federer going on to lose to Jo-Wilfried Tsonga in the quarters.
It was blowing a gale as Youzhny cut Federer’s lead to 3-2, but that was the last game the man from Moscow, also 30, won in the second set.
Youzhny, having turned to the dignitaries in desperation in the third game of the third set, brought up two break points in the fourth when he trailed 2-1, and gave a sustained cry of agony after failing to take the first. When the second slipped away too he turned away in resignation.
At 5-1 and 40-love down, Youzhny saved three match points and held serve. An unexpected turn of events. But when the fourth arrived in the next game, Federer had held back a treat and delivered the most elegant of volleys for the finishing touch.
