Andy Murray has triumphed in a hard-fought return to Masters-level tennis as he rallied from a set down to win 2-6 6-2 6-3 against Argentina’s Juan Ignacio Londero in the first round of the Shanghai Masters.

Murray, who won the Shanghai title on his last appearance in 2016, fell behind after two breaks in the first set but battled back to win in two hours and 17 minutes.

“Since I came back to play, these are by far the fastest conditions I’ve played in,” said Murray.

“So I struggled early on with my movement. But it was nice to be back and playing here again, get the win and hopefully start the next match quicker.”

Meanwhile, Croatia’s Marin Cilic stumbled to a shock first round defeat as he was beaten 6-4 6-4 by Spain’s Albert Ramos-Vinolas.

Ramos-Vinolas, who is ranked 46th in the world, broke Cilic’s serve once in each set to complete the victory in one hour and 23 minutes.

After dismissing one former grand slam champion, the 31-year-old will go on to face 20-time major winner Roger Federer in round two.

Canada’s Denis Shapovalov will take on top seed and defending champion Novak Djokovic next after he dismissed American Frances Tiafoe in a 6-4 6-2 win.

Murray will have to play much more confidently in his next test against Italian world No.12 Fabio Fognini, who beat American Sam Querrey 6-4 6-2.

There was more success for Britain as Cameron Norrie progressed with a 7-5, 6-2 victory over Frenchman Gilles Simon.

However, Kyle Edmund was beaten 6-4, 7-6 (7-3) by France’s Jeremy Chardy, who will play Germany’s Alexander Zverev next.

Two more Frenchman advanced to the second round after Benoit Paire dismissed Italian Marco Cecchinato 6-2 7-5, and Gael Monfils completed another Italian job in a 7-5 6-7 (1-7) 6-3 triumph over Lorenzo Sonego.
