Daniil Medvedev smashed a net camera in an angry outburst during his five-set Australian Open win over lowly-ranked wildcard Kasidit Samrej.
Medvedev reached the final for the third time at Melbourne Park 12 months ago but arrived late in Australia following the birth of his second child and was in deep trouble against 418th-ranked Thai Samrej. When the 23-year-old won the third set to go two sets to one up, fifth seed Medvedev repeatedly smacked his racket against the middle of the net, destroying a camera attached there.
