Del Potro stuns Stan after years of injury hell
Argentinian Juan Martin del Potro is making the most of his second coming at Wimbledon, while in the women's singles the Williams sisters powered through to the next round after tough tests.
Venus and Serena Williams endured rain delays and determined opponents in Christina McHale and Darya Kasatkina respectively, but held their nerves to progress.
For del Potro, it has been seven years since he scalped Roger Federer at his peak in the US Open final, and it was seven years of injury torment.
He's back now, with his wrist still not completely healed, but playing much like the man who stunned Federer in New York all those years ago.
Fancied fourth seed Stan Wawrinka was his victim yesterday, beaten 3-6 6-3 7-6 (7/2) 6-3, and as a word of warning for the rest of the field, Del Potro claims he may not be back to his best until 2017.
"I would like to be 100pc for the next season," said the world number 185, who on this form is a high-ranking seed in all but official status, but hasn't appeared at Wimbledon since 2013.
"I know how far I am from my high level … but it was great to come again. The crowd was unbelievable with me. The atmosphere was amazing. They have a respect for me."
Meanwhile, Wimbledon champion Novak Djokovic was saved by the weather last night. The Serbian, so unbeatable for large parts of the last 18 months, had just gone two sets down to Sam Querrey in his third-round match when the heavens opened for a fourth time on day five.
The Court One crowd hollered their disapproval, but there was no doubting the call was the right one - particularly for Djokovic, who had a chance to regroup ahead of a huge test in his bid to win all four grand slams in the same year.
