World number one Rafael Nadal takes on Argentine Juan Martin del Potro directly after Djokovic's match on Centre Court, and Brit Andy Murray, who misses the tournament through injury, cited the decision to have two games staged back to back was the correct one.
The setting was not the only thing alien to the defending champion.
Three-time Wimbledon champion Novak Djokovic has reached his eighth semifinal at the All England club. Anderson had 28 aces, 27 of them coming in the final four sets.
It was the biggest shock in a tournament already brimming with surprises, especially as Joahannesburg-born Anderson had not even won a set in their four previous meetings.
This was only the third time in Federer's 20 years of contesting Grand Slam matches that he lost one after taking the opening two sets; both of the other defeats came in 2011. But that turned out to be the least of his worries.
Update: Federer not only dropped his first set, but his second as well.
On Tuesday, Tendulkar, a self-admitted Federer fan, indulged in some banter with his fellow great.
The escape energised Anderson and he broke in the next game with a bludgeoning backhand off a weak second serve and then battled back from 0-40 to seal the third with an ace.

He said: "I just asked the chair umpire how did I deserve that warning?" "I don't think it really mattered, to be honest". That initial burst gave Federer 34 successive sets won at Wimbledon , equalling his own record set between 2005 and 2006.

A crosscourt forehand victor, a down-the-line backhand powershot, a sneak attack after a serve - Roger Federer is the master of them all.
The final set lasted 90 minutes, and it was captivating stuff.
The decider went on serve deep into double figures, before Anderson broke in the decisive 23rd game to set up a chance to serve the match - a chance he duly took.
Kevin Anderson dethroned Roger Federer to reach his maiden Wimbledon semi-final after sealing a dramatic 13-11 deciding-set victory on Wednesday.
"Sure, it's disappointing losing the next two sets after winning the first two and having match points". His last semifinal appearance at a Grand Slam was at the US Open in 2016, where he lost in the final to Stan Wawrinka.
This time it was Kevin Anderson and Gael Monfils who held up the Serbian, who said: "Post-match I heard that the organisers were planning to cancel my match if Monfils and Anderson went to a fifth".
"I just don't know exactly how I couldn't create more opportunities once the third set came around".
"I just kept telling myself to keep believing, and that today it would be my day". That's the mindset you need against someone like Roger.
