Both world No. 1s were among a slew of current top players and tennis legends who took to social media to celebrate the 20-time Grand Slam champion.

A year removed from his major debut against Novak Djokovic, the Danish teen has gone from starstruck to star in the making after reaching his first Roland Garros quarterfinal.

How would you describe the 23-time Grand Slam champion? Naomi Osaka, Carlos Alcaraz, and Coco Gauff drop some superlatives you can use.

Fans who invested time beyond singles showdowns at the Western & Southern Open this week hardly left the doubles court disappointed.

After reaching new heights with a Roland Garros quarterfinal, the Danish teenager struggled with the altitude before settling back down with a (mostly) straightforward win in D.C.

Meanwhile, Jessica Pegula cracks the Top 10, Coco Gauff surges to a new high of No. 13 and Holger Rune continues his breakthrough year by breaking into the Top 30.

Rune claimed Ruud confronted him after their tense four-set quarterfinal—an allegation Ruud denies—in the wake of criticism of his quick handshake.

The names and countries were similar, but their personalities couldn’t have been more different as Ruud overcame his Nordic neighbor in four sets to reach his first Grand Slam semifinal.

At the bottom of the men's draw, Andrey Rublev seeks a maiden major semifinal against former US Open champion Marin Cilic.

The 23-year-old from Norway and the 19-year-old from Denmark, setting national records, will now play each other in an all-Scandinavian quarterfinal.
