"I felt like I could have played on a bigger court," De Minaur doesn't understand the US Open organization

Alex De Minaur isn't making much noise at this US Open but is holding his ground for now. After his straight-set wins against Christopher O’Connell and Shintaro Mochizuki, the world No. 8 Australian conceded his first set of the tournament against Daniel Altmaier, who had upset Stefanos Tsitsipas in the previous round.

However, the German ultimately retired early in the fourth set (6-7, 6-3, 6-4, 2-0 ret). Still, De Minaur wasn't entirely satisfied and expressed his frustration about the court on which he played this match.

"It's a bit surprising for me, I'm not going to lie. I have nothing against Court 17, I've played good matches there in the past, but I felt like I could have played on a bigger court.

But hey, when things don't go the way I want, I just tell myself I need to win more matches. If I win enough, I know I'll play on bigger courts.

There's no point in complaining. It always comes back to the same mindset. My best option in these situations is to keep moving and, most importantly, win matches. I feel like I've flown under the radar throughout my career—it's nothing new.

My approach is to let my tennis do the talking, and I'm proud of that. I hope to stay here in New York for a long time. For me, this was the first step. Now, on to the second week, which I'm very excited about," concluded De Minaur, who will face Leandro Riedi, for Punto de Break.

The Swiss player also advanced via retirement, benefiting from Kamil Majchrzak's withdrawal (5-3 ret). Ranked 435th in the world this week, the 23-year-old has reached the fourth round of a Grand Slam for the first time in his career.
