Today on Tennis Channel: Four Grand Slam champions, three Top 10 players compete in Washington D.C.

There are five combined ATP and WTA tournaments taking place this week—and all of them are streaming on the Tennis Channel app.

Here's five things you need to know about Tuesday's tennis, and where you can watch each event.

Four Grand Slam champions—all women—are in action in Washington D.C., including Venus Williams.

The former No. 1, who made a winning return to the doubles court on Monday, will play fellow American Peyton Stearns in her first singles match in 16 months (since the 2024 Miami Open), and will look for her first singles win in 23 months (since the 2023 Cincinnati Open). She’s among a parade of major winners in action on Tuesday, alongside Naomi Osaka, Emma Raducanu and Sofia Kenin.

Meanwhile, on the men’s side in D.C., three Top 10 players take the court.

Lorenzo Musetti, Ben Shelton and Holger Rune—the current No. 7, No. 8 and No. 9, respectively—all play their first-round matches at the ATP 500 event. Shelton, who faces fellow American Mackenzie McDonald, will play his first career match as a Top 8 player, having just hit a new career-high ranking of No. 8 on Monday.

Top seed Linda Noskova kicks off her campaign at the other WTA event this week, in Prague.

She may only be 20, but Noskova already has quite the resume at her home event—she’s won 10 of her last 13 matches in Prague, reaching the semifinals in 2022, the final in 2023 and the semifinals again in 2024. The world No. 23 plays No. 249-ranked Anastasia Gasanova in the first round.

Rising star Justin Engel will try to keep the breakthroughs coming in Kitzbuhel.

The 17-year-old German, who faces Brazil’s Thiago Seyboth Wild in the first round of this clay-court event, recently reached his first ATP quarterfinal in Stuttgart, on grass. That made Engel the youngest man to reach a tour-level quarterfinal on grass in 40 years, since Boris Becker won Wimbledon in 1985.

Fresh off his first ATP final, Jesper de Jong begins his week in Umag.

The Dutch No. 2 just reached the first tour final of his career in Bastad, taking out Dutch No. 1 Tallon Griekspoor along the way (before falling to Italy’s Luciano Darderi). Now he’ll try to keep that winning momentum going at another ATP 250 clay-court event. He opens against No. 277-ranked Croat Mili Poljicak.
