Andy Murray stole the show during the first round of the US Open in more ways than one overnight, with the high temperatures in New York causing havoc.
The Scottish fan favourite surprised many tennis fans by taking the first set against world No.3 Stefanos Tsitsipas in their first round clash and ultimately pushing it to five sets.

It was a pleasantly surprising turn of form from one of the tour's most beloved players, with the match ultimately going the five set distance.
That meant fans got a much closer look at Murray's outfit, which had become drenched in sweat and unfortunately began to go somewhat see-through.
Murray's combination of white shorts and white underwear was an unfortunate one as he looked to potentially spring one of the upsets of the season against Tsitsipas.
The highly popular Tennis Podcast account tweeted perhaps the best summary of the situation.
"Not to lower the tone, but Andy Murray's shorts are absolutely soaked through and transparent right now. Read into that what you will," they wrote.
There were plenty of other amused reactions to the 34-year-old's unfortunate mishap.
Murray was also troubled by his shoes in the hot weather, with his soles becoming soaked and an extra pair not available.
The 34-year-old eventually stuck the hose of the on-court air conditioning into his shoes in an effort to dry them out between points.
Aussie trio crash out of US Open on day one
James Duckworth has suffered a crushing five-set defeat to join fellow Australians John Millman and Astra Sharma out the US Open exit gates.
Duckworth blew four match points in the third-set tiebreaker before succumbing 4-6 4-6 7-6 (9-7) 6-2 6-2 to Spain's Pedro Martinez.
Millman earlier slumped to a 7-6 (8-6) 7-6 (7-2) 6-1 first-round loss to Swiss qualifier Henri Laaksonen on day one at Flushing Meadows, while Sharma lost 6-0 6-3 to eighth-seeded French Open champion Barbora Krejcikova.

But the veteran's defeat, after entering the season's final grand slam under a fitness cloud, was nothing on Duckworth's gut-wrencher.
After hitting a career-high No.67 in the rankings last week, Duckworth was well on his way to continuing his watershed season before letting his huge opportunity slip.
The Sydneysider led 6-3 in the crucial breaker and then relinquished the fourth set in quick fashion to find himself fighting against the momentum.
He composed himself to gain an early break in the fifth only to concede six games straight to bow out after a tense and marathon affair stretching four hours 20 minutes.
Enjoying a breakout run to the Wimbledon third round last month, and also making round two at Roland Garros and Melbourne Park, Duckworth had been bidding to win matches at the four majors in the same year for the first time in his injury-plagued career.
There was also disappointment for Sharma, who was unable to extend her winning run from qualifying despite mounting a second-set fightback against Krejcikova.
After losing six of the first eight games, Sharma eventually submitted in one hour 14 minutes.
Nick Kyrgios, who faces 18th seed Roberto Bautista-Agut, and Alexei Popyrin, up against Radu Albot, play later on Tuesday.
