Karen Khachanov wins in a thriller to advance to the US Open semifinals (0:40)

Karen Khachanov advanced to the US Open semifinals with a hard fought victory over Nick Kyrgios. There is a time and a place for it.

1:03 AM ET

After reaching his first Grand Slam semifinal at the US Open, Karen Khachanov stood on the court with his arms raised. Nick Kyrgios took out some of his anger at the close result on his rackets.

He cracked his piece of equipment against the ground after the final point of the match. After grabbing another racket out of his bag, he reared back and hit that one on the sideline as well.

In a high-quality, topsy-turvy quarterfinal that began Tuesday night and ended more than 312 hours later at about 1 a.m., Nick Kyrgios bowed out in a high-quality, topsy-turvy match. There is a game in Arthur Ashe Stadium.

It's heartbreaking. "It's heartbreaking, like, I was the runner-up at Wimbledon in July." A lot of the other tournaments are a waste of time. You should show up at the grand slam. You are remembered by that.

"I feel the pain for him, I sawrackets were flying," said the man when asked about the display of disappointment.

Two spectators were kicked out of the game early after one gave the other a haircut. The late-staying spectators were loud in their support of the player. At one point in the fourth set, chair umpire James Keothavong told both players to respect each other.

I was ready. I was expecting the crowd to be more for him, that he was the favorite in their eyes.

The winner of Friday's match will play for a spot in the title match.

"I'm very proud of myself." From the beginning to the end, I was focused on the task at hand.

Both of them have booming serves and they combined for 61 ace. It was the second US Open men's match to feature players with at least 30 ace. In the 2004 quarterfinals, there was a fight between Andy Roddick and the other man.

More than 100 total winners were combined for by the two men.

The two real difference-makers were the number of unforced errors and the number of Russians. The man saved 7 break points.

The breakthrough at Wimbledon, and two recent victories over No. 1 Medvedev made him a popular pick to win his first Grand Slam title at the upcoming US Open.

The All England Club banned all players from Russia, Belarus, and other countries because of the invasion of Ukraine, which prevented Khachanov from playing at Wimbledon. At the beginning of the US Open, he was 150-1 to win.

The last game of the first and third sets was where the breaks of serve came from. After the opener, the player complained of a sore knee and was seen by a trainer.

He did not show any ill effects after play resumed and broke early in the second.

He had a chance to break at 4-all in the third but missed a forehand and spiked his racket. Keothavong was warned for unsportsmanlike conduct after he threw a drink and sat in his changeover chair.

Khachanov was within two points of victory as he was ahead 5-5. After holding on there, he dominated the subsequent tiebreaker to force a fifth.

After breaking to start the last set, he was up 3-1 and on his way.

He said that the expectations rise up when you are deeper. I moved forward.
