Today on Tennis Channel: More blockbuster match-ups highlight final day of play at Laver Cup

There's a total of five men's and women's events taking place this week—and all of them are streaming on the Tennis Channel app.

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

A star-studded line-up takes the court on the final day of play at the Laver Cup in San Francisco.

Team World heads into Day 3 with a 9-3 lead in points, so Team Europe has some work to do if they want to catch up—and they're pulling out all the stops.

First up will be a doubles match pitting Carlos Alcaraz and Casper Ruud against Alex Michelsen and Reilly Opelka, followed by up to three singles matches—Alex de Minaur against Jakub Mensik (De Minaur leads 2-0), Alcaraz against Francisco Cerundolo (Alcaraz leads 3-0) and Alexander Zverev against Taylor Fritz (Fritz leads 8-5). The Zverev-Fritz head-to-head is perhaps the most intriguing of them all—that was once a 5-3 lead for Zverev, but Fritz has won the pair's last five meetings in a row, including four last year (Wimbledon, US Open, Laver Cup and the ATP Finals) and one this year (Stuttgart). The American just took out the No. 1-ranked Alcaraz in straight sets on Saturday, so why not another win over the No. 3-ranked German?

Every win on Day 3 counts for three points as Team Europe and Team World continue their quest for 13 points, and the Laver Cup. In the event of a 12-12 tie, a final overtime doubles match will be played to decide a winner.

The United States and Italy will battle it out in Shenzhen, China for the Billie Jean King Cup title.

For the Americans, this has been a welcome return to form—they're through to the Billie Jean King Cup final for the first time since 2018, and today they'll try to win the title for the first time since 2017. For the Italians, this is becoming a habit—this is their third straight final at this event, having been runners-up two years ago (to Canada) and champions last year (over Slovakia).

But there's another theme today, and that's revenge—the United States have a 9-5 career record against Italy at this event, but that was 9-0 before 2000 and 0-5 since 2000. A stacked American squad that includes Jessica Pegula, Emma Navarro, Taylor Townsend, McCartney Kessler and Hailey Baptiste will try and turn that pattern around on Sunday against a similarly-stacked Italian squad led by Jasmine Paolini, Elisabetta Cocciaretto and Sara Errani.

Iga Swiatek takes on Ekaterina Alexandrova for the WTA 500-level title in Seoul.

After they both pulled double duty on Saturday—winning both their quarterfinal and semifinal matches, with rain washing out play on Friday—it's down to the Top 2 seeds, Swiatek and Alexandrova, for the title in Seoul.

After going more than a year without even reaching a WTA final, Swiatek has now reached the final at four of the last six events she's played, a stretch that dates back to the grass-court season and includes titles at Wimbledon and Cincinnati. Today she'll try to win her third title of the year, but Alexandrova is always a dangerous customer, with five Top 10 wins to her name this year—as well as a WTA 500-level title on the indoor hard courts of Linz.

Swiatek leads the head-to-head, 5-2, winning both of their meetings this year in straight sets—including one just a few weeks ago at the US Open.

Lorenzo Musetti will try to reach his first semifinal since Roland Garros in Chengdu.

The Italian reached the semifinals or better at four straight tournaments during a breakthrough clay-court season, culminating in a semifinal showing at Roland Garros, and today he'll try to reach his first final four since then as he takes on qualifier (but former Top 20 player) Nikoloz Basilashvili.

All four quarterfinals take place at the ATP 250 event today, including a clash between the last two Americans standing, Brandon Nakashima and Marcos Giron—Nakashima won the pair's only previous tour-level meeting in straight sets in the final of San Diego, also on hard courts, in 2022.

Daniil Medvedev will try to reach his first semifinal since the grass-court season in Hangzhou.

The 2021 US Open champion and former No. 1 hasn't been to the final four at an ATP event since reaching the final of Halle midway through the grass season, where he fell to Alexander Bublik—and if he beats Chinese wild card Wu Yibing today, his reward could be a rematch with Bublik, who faces Czech lucky loser Dalibor Svrcina in his quarterfinal match today.

Like Chengdu, all four quarterfinals take the court in Hangzhou today, and there's one American left standing at the ATP 250 event in Learner Tien. He faces French qualifier Valentin Royer today.
