Ready, set, serve – the 2023 U.S. Open is here.

The world's top tennis players are set to descend upon New York next week for the fourth and final Grand Slam of the season, including defending champions Carlos Alcaraz of Spain and Iga Swiatek of Poland, who are both favorites to repeat.

But don't count out Americans Coco Gauff, Jessica Pegula, Frances Tiafoe and Taylor Fritz, who will surely have the rowdy hometown crowd on their side. The last Americans to win the U.S. Open were Sloane Stephens in 2017 on the women's side and Andy Roddick in 2003 on the men's side.

OPINION: After second tournament title this summer, Coco Gauff could be the US Open favorite

Here's everything you need to know about the 2023 U.S. Open:

When does the 2023 U.S. Open begin?

The 2023 U.S. Open main draw begins Monday, Aug. 28 and runs through Sunday, Sept. 10 at the USTA Billie Jean King National Tennis Center in New York.

What TV channel is broadcasting the 2023 U.S. Open?

The U.S. Open tournament will be televised on ESPN.

Is there a live stream for the 2023 U.S. Open?

All matches can be live streamed on the ESPN website, the ESPN app and ESPN+. Streaming is also available on FuboTV and SlingTV.

Who are the U.S. Open defending champions?

Spain's Carlos Alcaraz and Poland's Iga Swiatek will look to defend their titles at the 2023 U.S. Open.

The last player to win back-to-back U.S. Open titles on the men's side was Switzerland's Roger Federer, who won the tournament five times in a row from 2004 to 2008. American Serena Williams completed the three-peat from 2012-2014, the last woman to repeat titles at the U.S. Open.

Will Novak Djokovic play in the 2023 U.S. Open?

Yes.

Djokovic has not played at the U.S. Open since 2021, when he lost his bid for the Grand Slam – winning all four majors in a calendar year – to Russian Daniil Medvedev in the final. Djokovic was unable to play in the 2022 U.S. Open due to his vaccination status. He has won the U.S. Open title three times in his career: 2011, 2015, 2018.

Who are the players to watch at the U.S. Open?

All eyes will be on Alcaraz and Djokovic. Alcaraz denied Djokovic his 24th Grand Slam title with a win at Wimbledon in July, marking the young Spaniard's second slam win. But Djokovic flipped the tables on Alcaraz at the Masters 1000 Western & Southern Open tournament in Cincinnati on Sunday, winning 5-7 7-6 (7), 7-6 (4) in the longest best-of-three sets final in ATP Tour history since 1990.

Will they meet again in the final? "I hope we meet in New York. That would be fun – well, for the fans, not for me," Djokovic said after accepting his Western & Southern Open tournament trophy.

American Coco Gauff is another contender to keep an eye on. She won the Western & Southern Open women's title and the Washington Open in August and is hitting her stride right before the U.S. Open, another hardcourt tournament.

The U.S. Open main draw will be announced on Thursday, Aug. 24.
