MELBOURNE, Australia (AP) — Sebastian Korda comes by his athleticism and competitive instincts honestly. From Dad, the 1998 Australian Open champion. From Mom, also a former professional tennis player. And from two big sisters, both current golf pros.

Add in some mentorship from eight-time major champ Andre Agassi and a couple of coaches, including former player Radek Stepanek, and maybe it shouldn’t be all that surprising that Korda, a 22-year-old American never past the fourth round at a Grand Slam tournament, would manage to eliminate two-time runner-up Daniil Medvedev at Melbourne Park.

Korda’s attacking brand of tennis carried him past No. 7-seeded Medvedev 7-6 (7), 6-3, 7-6 (4) in the Australian Open’s third round Friday night, the latest in a string of victories by young men from the U.S. against top players this week.

“I always was told how good of a tennis player I can be. Now (I’m) just getting the right people around me, building a really solid team, just trusting the process,” said the 29th-seeded Korda, who was the 2018 junior champion in Australia. “I’m growing as a person, as a player. Just trying to do the right things. Just have fun, enjoy it — good things will happen.”

This result comes on the heels of two other attention-grabbing victories by players from the U.S., whose men last won a Grand Slam title 20 years ago. On Wednesday, Mackenzie McDonald beat No. 1 seed Rafael Nadal. On Thursday, Jenson Brooksby beat No. 2 seed Casper Ruud.

Now it was Korda’s turn to add his name to the list with a game Medvedev described as “kind of different from everybody.”

Medvedev won the U.S. Open two years ago and made it to the final in Australia in 2021, when he lost to Novak Djokovic, and 2022, when he lost to Nadal after holding a two-set lead. The Russian also was briefly ranked No. 1 last season.

On this night in Rod Laver Arena, it was Korda who dictated most of the points, who put his shots right where he wanted them, who charged forward with verve and slick volleys. He even threw in the occasional drop shot, for good measure.

He compiled nearly twice as many winners as Medvedev, 50-28, and won the point on 75% of his trips to the net, 36 of 48.

“I kind of knew what I had to do. I stuck with it, even when I was going up and down with the emotions,” Korda said.

How would he describe that game plan?

“Just go for it,” he said with a laugh.

Korda broke Medvedev — who said afterward his right wrist and forearm were bothering him — the first time he served in each set.
