Tsitsipas dominates Sinner to reach the Australian Open semifinals (1:28)

After a straight sets win over Jannik Sinner, Stefanos Tsitsipas advanced to the Australian Open semifinals. The song is called "1:28."

3:04 AM ET

The ninth-seeded Felix Auger-Aliassime was beaten by the seventh-seeded Daniil Medvedev in the quarterfinals of the Australian Open.

The US Open champion's bid to become the first man in the Open era to win two Grand Slam titles is still on track after the 4-hour, 42 minute comeback victory.

The French Open runner-up will play the Russian in the semifinals of the Australian Open. The winner of last year's stage lost in the final to Novak Djokovic.

No. 11 Jannik Sinner was beaten by Tsitsipas.

Facing defeat, Medvedev got a break. A six-minute delay in the third-set tiebreaker for the roof on Rod Laver Arena to be closed due to a rain shower swung his way.

After dominating the first two sets, Auger-Aliassime only won one of the last six points in the tiebreak. He missed a match point in the 10th game of the fourth set.

The man saved it with a big first serve and then held on with an overhead winner.

I was not playing my best and Felix was serving unbelievable, so I asked Novak what to do.

I thought I was going to make him work. If he wants to win it, he has to fight to the end.

The 25-year-old Russian broke Auger-Aliassime's serve in the next game game and held to level the match at two-set all. The 21-year-old Canadian double-faulted in the third game of the deciding set, which gave him another service break.

It was not over yet.

After saving a match point, Medvedev saved two break points before closing it out about an hour later.

Auger-Aliassime had lost all three previous matches against the second-ranked Medvedev, including a straight-set loss in the U.S. Open semifinals last September.

He was the one who was the most aggressive in the first two sets, keeping Medvedev off balance with his forehand and up-tempo game.

It forced him to play more inside the baseline in the third and fourth sets.

The crowd was making noise between his first and second serves, and that's when Medvedev had his leg taped.

He dropped serve in the 11th game and twice in the first set tiebreak after breaking back when Auger-Aliassime was serving.

In the second or third sets, he didn't get a look at a break point, but when he did, he converted.

He has been the top seed since the defending champion was deported for failing to meet Australia's strict COVID-19 vaccine rules.

Another person who could benefit is Nadal.

The Spaniard will play the Wimbledon runner-up in the other semifinal match to try and break a tie with Roger and Novak.
