Andy Murray picked up his best win of the year so far with a straight-sets victory over Tomas Martin Etcheverry at the Miami Open.

Murray swept past the Argentinian, ranked 30 in the world, 7-6 (0) 6-3 in a rain-interrupted match to reach the third round.

The 36-year-old Scot gained a measure of revenge for his defeat by the same player in the first round of the Australian Open in January.

Murray will face Czech youngster Tomas Machac, who beat Russian world number six Andrey Rublev, in the next round.

British number one Cameron Norrie will meet third seed Daniil Medvedev in the round of 64 after escaping Italy’s Flavio Cobolli 7-5 6-7 (4) 6-2 in two hours and 34 minutes.

Nicolas Jarry ended fellow Briton Jack Draper’s challenge, however.

Jarry, the world number 23 from Chile, beat 22-year-old Draper 7-6 (5) 4-6 7-6 (2).

Compatriot Dan Evans was also bundled out in a gruelling 7-6 (3) 3-6 7-6 (7) loss to American Christopher Eubanks.
