Shelton promises another 'war' with friend Tiafoe at US Open

The U.S. Open enters the third round on Friday as the world's top players battle for Grand Slam glory in New York.

Men's defending champion Novak Djokovic, who is eyeing a fifth U.S. Open title, takes on Australia's Alexei Popyrin while women's holder Coco Gauff meets Ukraine's Elina Svitolina.

An all-American clash between Ben Shelton and Frances Tiafoe offers a rematch of last year's spectacular quarter-final.

Here are the latest results and highlights:

TOP MEN'S MATCH: SHELTON v TIAFOE

Shelton has beaten Tiafoe both times they have met but the wins have never come easy.

"These are the type of matches that I love, that I live for ...," Shelton said. "It will be a war just like the last two times we've played. "I know that the people love him here. Probably more than me. He's electric here, and his crowds are electric here."

Tiafoe also spoke fondly of Shelton and said he anticipated a tough match.

"He's young, funny, cracks jokes. Just about as immature as I am," Tiafoe joked. "He's got one of the better serves on the tour, no question. Especially a lefty, he hits all the spots, changes pace quite well. It's going to be tough but I'm super excited."

TOP WOMEN'S MATCH: GAUFF v SVITOLINA

Svitolina beat Gauff in straight sets the first time they played each other in 2021 but their latest clash at the Auckland Open in January saw the American fight back from a set down to get the win.

The 20-year-old defending champion said she would have to bring her best on Friday.

"I think she's a good all-court player. She can do pretty much everything. She's really solid from the back. When I played her in Auckland, we had a lot of physical points," Gauff said.
