Two semi-finals, two memorable Wimbledon matches. The bar was set high from the start and maintained throughout the day, as a wacky Wimbledon that has seen both its gentlemen's and ladies' draws thrown into turmoil with upsets ended up the top two seeds in the men's decider. Read what storylines shook out on Day 11 of The Championships.
Match of the Day  Novak Djokovic def.  Juan Martin Del Potro 7-5, 4-6, 7-6(2), 6-7(6), 6-3
For all the things that The Championships 2013 will be remembered for, let's hope this match rises to the top. It was an epic encounter from the start, with the seven-time major champion hitting his patented strokes off the ground but being matched from the other side of the net, the 2009 US Open winner doing well to stay with Novak Djokovic as he blasted away. As the afternoon wore on, it looked inevitable that Djokovic would close the match in relatively comfortable fashion and had two match points to do so in the fourth set tie-break. But Del Potro saved those and ran off two more points to steal the set and force a decider. It was the 2011 Wimbledon champ who came out on top, though the exchanges, the quality of play and the drama that encompassed the 4 hour, 43 minute battle will be hard to repeat in semi-finals to come.
Honorary Match of the Day  Andy Murray def.  Jerzy Janowicz 6-7(2), 6-4, 6-4, 6-3
It's a scoreline that appears rather straight-forward for the British No.1, but it was anything but on Friday evening. Taking to the court just around 6pm, Murray fell down a set and then trailed by 4-1 in the third set. It was then that he reeled off five straight games, taking a two-sets-to-one lead before officials decided to close the roof due to fading light. It was a decision that Murray - and therefore all of Britain - greatly disliked (he did have the momentum after all), but 30 minutes later they were back on court and Murray closed the match with relative ease as Janowicz seemed to fade with the setting London sun.
Upset of the Day  Casey Dellacqua and Ashleigh Barty def.  Anna-Lena Groenefeld and Kveta Peschke 7-6(6), 6-2
They may be 11 years apart, but Australians Casey Dellacqua, 28, and Ashleigh Barty, 17, appear to be two players on the same wavelength. On Saturday the duo - who have played less than 10 tournaments together - booked a place in their second major final this year having been runners-up at the Australian Open to top seeds Sara Errani and Roberta Vinci. They did so by beating the more experienced team in Groenefeld and Peschke, the latter having been the only woman remaining in the draw who had won a major. In Sunday's final the Aussies face Peng Shuai and Su-Wei Hsieh, the No.8 seeds.
Stat of the Day
Not only was the quality high on Friday in the first semi-final, but it was a sustained quality, as well. In fact, the Djokovic-Del Potro was the longest men's semi-final in Wimbledon history, outdoing Boris Becker and Ivan Lendl's 1989 effort. That match was 4 hours, 1 minute while today they were on court for 4 hours, 43 minutes.
It's been written many, many times already over the last few days, but it's worth writing again: Jerzy Janowicz is the first Polish man into the semi-finals of a Grand Slam - ever.
Quotes of the Day
"It was one of the best matches that I've been part of, one of the most exciting definitely. It was so close, really, you couldn't separate us. That's why he's a Grand Slam champion, he's right at the top." - Novak Djokovic on his battle with Del Potro
"It was very different to last year. This year there was a lot of expectation on me to get to the final from early on. I was just delighted to come through and get another chance to play in a Wimbledon final. It will be a tough match [against Djokovic]. Him and Del Potro played an incredible match today. Novak is moving very, very well and it'll be tough." -Andy Murray on the expectations heaped on him

'Did You Just see?' of the Day
Jude! Anna! Centre Court became quite the star-powered place as Vogue editor Anna Wintour and actor Jude Law were both spotted there, staying around through the finish of a long day's play. The always-entertaining Mansour Bahrami was there, as was 1999 Wimbledon champion Lindsay Davenport and Stefan Edberg, who won here in 1988 and 1990.

20:08It brings me no pleasure but it's time to bring the curtain down for another year. Seemed somehow appropriate to leave the last word to Roger Federer. Thanks a billion for reading. What a fortnight, what a final, fast forward to 2015 please...
20:03"I already have seven. It's not like I need another one. But it would have been awfully nice to have it. I think that's what the feeling was of the people, and I felt that... I know they love tennis. They love tennis after we're all gone."View all
