Wawrinka hit by rain delays
Stan Wawrinka's coach admits he will need to pull off a feat that is "not really human" if he is to win his first Wimbledon title.

The Australian Open champion was the main victim of Saturday's bad weather and now faces potentially having to play five matches in seven days.
Most singles matches were completed after much of Saturday was washed out but Wawrinka's third-round match against Denis Istomin had already been postponed along with the clash between John Isner and Feliciano Lopez - the winners will meet in the next round.
Because there is no play on middle Sunday at Wimbledon, those matches will now be played on Monday, the fourth round on Tuesday and quarter-finals on Wednesday.
Magnus Norman, who has guided Wawrinka into the world's top three, told Press Association Sport: "It's tough but I know the organisation and the referee are trying to be fair to all the players because they also cancelled Lopez and Isner.
"It's a tough situation because if he wants to go through here he has to win five best-of-five-set matches in seven days so it's going to be really hard, and three days in a row.
"It's not really human but we're not complaining. We know what we have to do and we'll just try to focus on one point at a time and one match at a time."
To try to be fair to all the players in the bottom half of the men's draw, no fourth-round matches in that section will be played on Monday, meaning all Tuesday's winners will have to play again on Wednesday.
Norman backed the decision, saying: "That's one thing that they've done to try to be fair to all the players.
"It's not an easy decision for anyone because we have also the Sunday off with the tradition at Wimbledon.
"The best thing for the players would be to play today and have Monday off but you have to take everything into consideration and I think they're doing a great job trying to be fair to everyone."
World number one Rafael Nadal and fourth seed Roger Federer are also affected.
Both know their opponents already, with Nadal due to take on new teen star Nick Kyrgios and Federer facing Tommy Robredo, but must wait until Tuesday to play.
Speaking after his third-round win under the roof against Santiago Giraldo but before the order of play was released, Federer said: "I guess Stan's section and Isner's section, they have to play three straight days now.
"There could be 15 sets right there, long sets. These guys are all fit enough to handle it, but it can have an impact, no doubt.
"I might be also impacted, I might not play on Monday now. You can't choose always. It is what it is and you have to adapt to it."
Meanwhile, Nadal said of possibly having to play two days in a row: "That's not a positive thing."
Another third-round match will need to be completed on Monday after Kei Nishikori and Simone Bolelli ran out of light tied at 3-3 in the fifth set.
The top half of the men's draw will all play their fourth-round matches on Monday.
Wimbledon champion Andy Murray takes on Kevin Anderson while the standout match sees top seed Novak Djokovic play 14th seed Jo-Wilfried Tsonga.
Djokovic knows how dangerous the unpredictable Frenchman can be, and said: "I expect him to serve well. I think that's his advantage.
"Coming to the net, he's a very aggressive player. If he's on, if he feels good on the certain day, he can beat anybody really."
Tsonga will have been the player most grateful for his weekend off after playing every day last week, his first and second-round matches both having gone five sets and extended into a second day.
Grigor Dimitrov will bid to reach the second grand slam quarter-final of his career when he takes on Argentina's Leonardo Mayer while Marin Cilic, who knocked out sixth seed Tomas Berdych on Friday, meets Jeremy Chardy.
