Severe downpours in Florida wreaked havoc on the Miami Open schedule, with Andy Murray and Jannik Sinner among a host of players who had their second-round matches suspended due to rain.

Murray will resume play on Saturday against Argentina’s Tomas Etcheverry with the score tied at 3-3 in the first set.

Australian Open champion Sinner’s first set against fellow Italian Andrea Vavassori was on serve after five games, while Canada’s Denis Shapovalov held a 2-1 advantage after an early break in his first set with Greek 10th seed Stefanos Tsitsipas.

In Friday’s completed matches, fifth seed Andrey Rublev was upset 6-4 6-4 by Tomas Machac of the Czech Republic while 14th seed Ugo Humbert defeated Botic van de Zandschulp 6-4 6-3.

Murray previously outlasted a wilting Matteo Berrettini to advance to the second round of the Miami Open.

The former world number one wrote on the court-side TV camera that there is ‘life in the old dog yet’ after pulling off an impressive comeback victory.

Meanwhile, Murray has revealed he is still unsure exactly when this summer he will retire as a tennis player.

He said: “I would love the chance to play in another Olympics, but also genuinely only if I felt like there was a chance of winning a medal.

“I’m also very conscious that because of how amazing my experiences at the Olympics have been, I would want to be there by right and not just take one of the other guys’ spots, because it is a brilliant opportunity.

“We have top doubles players (Joe Salisbury and Neal Skupski are ranked inside the world’s top 10) and also Jack (Draper), Cam (Norrie) and Evo (Dan Evans) in singles as well.”
