Medvedev, a US Open finalist last year, arrived in Melbourne in red-hot form, winning all his singles matches at the inaugural ATP Cup before a three-set defeat to seven-time Australian Open champion Novak Djokovic in the semifinal.

The 168th-ranked Martinez, who had never won a tour-level match before his Australian Open debut this week, could only break his opponent’s serve once and created three more chances for a break in the sixth game of the third set but did not have enough to challenge the clinical Russian.

Medvedev’s nose started bleeding while he was up 5-0 in the second set and he was back on court firing on all cylinders after a medical timeout to set up a third round clash against Spaniard Jaume Munar or local hope Alexei Popyrin.
