• Russian struggled to 6-2, 4-6, 3-6, 6-1, 6-2 success
• Rune also needed five sets to make it past Zhang

Daniil Medvedev smashed a net camera in an angry outburst during his five-set Australian Open win over the lowly ranked wildcard Kasidit Samrej.

Medvedev, the fifth seed, reached the final for the third time at Melbourne Park 12 months ago but arrived late in Australia after the birth of his second child and was in deep trouble against the world No 418 from Thailand. When Samrej won the third set to go two sets to one up, Medvedev repeatedly smacked his racket against the middle of the net, destroying a camera attached there.
