Medvedev

Nick Kyrgios stunned defending champion Daniil Medvedev 7-6(11), 3-6, 6-3, 6-2 at the US Open on Sunday evening to reach the quarter-finals at Flushing ...

From the moment of his gaffe, Kyrgios dominated with his big serve and never allowed Medvedev to get comfortable. By rule, if a ball does not land on your side of the net and spin back to your opponent's side of the court, you are not allowed to touch the ball on that side. Kyrgios put a finger up in celebration, thinking he had just earned a spot on the highlight reel. The set got complicated as the Australian rediscovered his focus, but Kyrgios missed a neutral backhand long to allow his opponent to level the clash. Kyrgios put on the pressure from there, using his drop shot to great effect in the latter stages of the tie-break. Leading 1-0 and at 30/30 on Medvedev's serve, the 23rd seed rushed around the net and swatted away a ball that was not going to land anywhere close to the net. Kyrgios was unable to sustain his momentum, though, playing a poor opening service game in the second set. On the third of those set points, at 8/7, Kyrgios hit a tricky backhand volley that just clipped the singles line. Later in the first set, he would mix it up to give his big-serving opponent different looks.

"What a place to do it," Kyrgios said.

In Sunday's match at the U.S. Open against No. 1 seed Daniil Medvedev, Nick Kyrgios lost a crucial point in perhaps the most careless way possible.

Subsequent to the exchange, he mentioned to ESPN’s Patrick McEnroe who was sitting courtside that he didn’t know it was against the rules. Kyrgios is no stranger to on-court antics, including frequent racquet smashing and berating supporters in his coaching box. It’s hard to believe that Kyrgios, who has been playing tennis pretty much his whole life and made the Wimbledon final this year, did not know. In fact, Kyrgios had the break point all but secured when his passing shot popped straight up in the air off of Medvedev’s racquet. The chair umpire immediately awarded the point to Medvedev, but the confusing part is that Kyrgios was apparently unaware he couldn’t do that. In Sunday’s round of 16 match at the U.S.
