Australian Open: Jannik Sinner also beat Karen Khachanov and reached the quarterfinals without dropping a set

“The sinner can take another step forward every time he has to,” said expert Boris Becker. Eurosport “The first week was perfect,” he was impressed.

The South Tyrolean player has now reached the quarter-finals for the sixth time in his 17th Grand Slam appearance. Last year, Sinner reached the semi-finals at Wimbledon and then played a strong second half of the season.

“I'm very happy with this win,” Sinner said. “We have very similar styles, and sometimes it's like a game of ping-pong between us.”

After reaching the ATP Finals final and winning the Davis Cup with Italy, the 21-year-old appears to have carried his strong form from the fall into the new year.

Even without the support of his noble fans “Karuta Boys”, Siner once again showed a focused performance against Khachanov.

His “poker face” was partly just a façade, he said in his on-court interview: “On the outside I try to look calm, but inside you are preoccupied with a lot of emotions and feelings during a tennis match.”

Meanwhile, Khachanov has failed to find the success he did last year in Australia when he reached the semi-finals. The Russian has also been unable to improve his poor record against top 5 players – which now stands at 1:19.
