A monstrous forehand down-the-line, the clap of thunder. Earlier in the day Sam Querrey had smiled when he was unhappy while Marin Cilic - the eventual winner - scowled when he was elated. A shout that matched the scream of the shot and a smile that sparkled like the late-afternoon sun.
Elsewhere Heather Watson and Henri Kontinen continue their defence of the mixed doubles in a semi-final clash against Bruno Soares and Elena Vesnina on Court No 1. But the Croat's argument carried greater punch. At Wimbledon this year, his draw opened up when Rafael Nadal lost to Gilles Muller in the fourth round.
On Friday, BBC One released the teaser announcing that the identity of Doctor Who's 13th Time Lord will be revealed on after the Wimbledon men's singles final on Sunday.
Roger Federer's spoof Twitter feed couldn't resist a mild swipe at his fallen rivals as the History Man metaphorically picked his way through the bodies of the injured for yet another Centre Court engagement. In the victory, Federer won 84 percent of his first serve points and 60 percent of his second serve points.
During the semifinal against Tomas Berdych, Federer was able to summon his serve almost every time he was down to pull even and ward off break points.
Win or lose tomorrow, Federer says he has not set any date for retiring from the sport. So whatever was possible to do, then I was trying to do so.
" 'I still know that it's a big mountain to climb, ' Cilic said".
So the first question put to 2016 runner-up Milos Raonic after his 6-4, 6-2, 7-6 (4) loss to the seven-time Wimbledon champion in the quarterfinals Wednesday was: What does a guy have to do to beat Federer?
"That really settles me", Querrey said of that opening set.
He's hardly the first to realize that, of course. "But I believe that I am ready". When he broke me back, he played a great game.
"When you see that they're there for you, it's a bit of an unusual feeling".
"I'm just very happy that I'm still doing so well".
Sam does have a big enough game to hurt anyone. "I would say I played throughout the match really a high level". "Yeah, I guess the break is something that I will have to consider right now".
Either way, the next few years are going to be a fascinating time for the men's game. His string of quick victories in the playoffs has been phenomenal. And if Cilic comes out on top, the Croatian will be No. 5, ahead of Federer. The beast of a matchup also had its moments of beauty.
The 37-year old will overtake sister Serena's record set when she was 35 at the Australian Open in January.
Querrey was playing his own first grand slam semi-final at the 42nd attempt, but the American looked far from out of place.
Being two sets up, he went over the Czech in the third set forcing him to improvise.
