The conditions were the hot topic of conversation at the US Open on Tuesday.
Four men were unable to complete their matches because of the heat and humidity while Wimbledon champion Novak Djokovic was in trouble in his clash with Marton Fucsovics before recovering to win in four sets.
There were victories for Roger Federer and Maria Sharapova but Johanna Konta’s grand slam woes continued as she lost 6-2 6-2 to sixth seed Caroline Garcia.
Picture of the day
Canada’s Peter Polansky has achieved an unlikely first by getting into each of the four grand slams in 2018 as a lucky loser. Should a player pull out of the tournament prior to their first-round match, they are replaced by a player who lost in the final round of qualifying, drawn by lots from among the highest-ranked players. And Polansky’s name has come out of the hat each time. He has not made it any further, losing here to fourth seed Alexander Zverev, but his good fortune has earned him more than £150,000.
Stars and stripes
The other British player left in the singles draw, Cameron Norrie, faces Serbia’s Dusan Lajovic on Court 10 as he bids to reach the third round of a grand slam for the first time.
Victories for Serena and Venus Williams over Carina Witthoeft and Camila Giorgi respectively would set up a first grand slam meeting between the sisters since last year’s Australian Open final, while Rafael Nadal faces Vasek Pospisil.
