The frustrated Russian whacked his racket five times into the net after dropping serve in the third set before rallying to claim the match 6-2, 4-6, 3-6, 6-1, 6-2 in the afternoon sun at Rod Laver Arena. 

The tantrum earned fifth seed Medvedev a code violation for racket abuse and held up play before the fourth set as staff swept up debris from the court. After the match though, Medvedev was full of praise for the youngster in his on-court interview.

“He plays like this every match, life can be good, money, girls, casino, whatever,” he said. “I wish he can play like this every match.”

Samrej is the first Thai in a men’s Grand Slam main draw since Danai Udomchoke qualified for the 2012 Australian Open. Medvedev will face American qualifier Learner Tien for a place in the third round next.

In another big match, Australian number one Alex de Minaur moved into the second round with a 6-1, 7-5, 6-4 win over dangerous Dutchman Botic van de Zandschulp. De Minaur is widely regarded as Australia’s answer to end the country’s 49-year wait for a men’s singles champion at Melbourne Park.

De Minaur will face American qualifier Tristan Boyer, who defeated Argentine Federico Coria 6-3, 6-7(3), 4-6, 7-5, 6-1, in the second round.
