MELBOURNE, Australia – Conditions at Melbourne Park over the weekend were pretty brutal.

Which had American junior Dominick Mosejczuk flat on his back, just a few points away from defeat in the third set of his first-round singles match.

He was about as pale as his ballcap, and he was down on the court for quite awhile.

It was a scary sight. And yet for Mosejczuk, there was a happy ending.

Mosejczuk ended up rising and prevailing in a 6-4, 2-6, 7-6 (10-8 in the match tiebreak) victory over 16-year-old Nikita Bolozertsev of Ukraine.

He was pretty happy when it was all over, understandably – and so were his family and others who were there supporting him.

The break was a long one after he hit the deck, though, and we’re not sure that was all that fair to his opponent, – who held up better physically but had to wait through the incident and the care taken to make sure Mosejczuk was okay. But it is what it is.

Here’s what it looked like.

He recovered well. Mosejczuk and his fabulously-named doubles partner, fellow American Maximus Dussault, played their first-round doubles match late Monday afternoon – although they went down, 10-8 in the match tiebreak.

Mosejczuk plays Chen Kuan-Shou of Taipei, a 16-year-old ranked No. 40, Tuesday in the second round of singles. It’s a good break; Chen went through when British No. 6 seed Oliver Bonding retired down 1-4 in the third set of their first-round match.

Dominick Mosejczuk bio

Mosejczuk turned 18 last week – and so has one of those helpful “early year” junior birthdays in that he can maximize and still play those events in 2025 while being one of the oldest kids in the draws.

He’s tall with a good serve and good variety in his game, born and raised in the shadows of the USTA National Tennis Center in Queen’s. Mosejczuk spent several years at the John McEnroe Academy, and at the BTT Academy in Spain, before joining the USTA’s Player Development program back at home.

He won the Orange Bowl 16s in 2023, and came into the junior Australian Open at a career high No. 24 in the ITF junior rankings.

Mosejczuk made his junior Grand Slam debut at a relatively late age – only last summer at the US Open, and even then he was on a wild card. He upset current world No. 8 Hayden Jones (who impressed as a wild card into the men’s singles qualifying in Melbourne) in the first round before going down in the third round to eventual champion Rafael Jodar.

In the tuneup to the AO event in Traralgon last week, he was beaten by No. 1 seed Jan Kumstat of the Czech Republic in the second round.
