Aslan Karatsev has beaten Felix Auger-Aliassime to become the first man since 1996 to reach the quarterfinals on his Grand Slam debut.

The 27-year-old Russian qualifier dropped the first two sets but lifted his level and cut down his error-rate to beat the 20th-seeded Auger-Aliassime 3-6, 1-6, 6-3, 6-3, 6-4.

Not since Alex Radulescu at Wimbledon in 1996 has a player on debut reached the men’s quarterfinals at a Slam. He’s the first qualifier since Bernard Tomic at Wimbledon in 2011 to reach the last eight at a major.

The No. 114-ranked Karatsev said it took him two sets “to find a way how” to break down Auger-Aliassime’s game.

He’ll play either U.S. Open champion Dominic Thiem or Grigor Dimitrov next and he says he doesnt’ have a preference.

He said: “I’ll be ready for anyone.”

Serena Williams has returned to the Australian Open quarterfinals by getting past No. 7 seed Aryna Sabalenka in three sets.

The 6-4, 2-6, 6-4 victory put Williams one step closer to her record-tying 24th Grand Slam title overall and eighth championship at Melbourne Park.

Her most recent major trophy came at the Australian Open in 2017.

This was Williams’ 62nd fourth-round match at a major tournament — and Sabalenka’s second.

They played a similar brand of powerful tennis but Williams was barely better, stealing the last two games after what had been a 4-1 lead in the final set evaporated.

The 39-year-old American next faces either Simona Halep or Iga Swiatek.
