The US Open day one scheduled features several former champions in action.
On Arthur Ashe alone, fans will be treated to defending champion Naomi Osaka in the evening in her match against Marie Bouzkova. But earlier, Andy Murray and Stefanos Tsitsipas meet for a very first time.
The 34-year-old Murray who won the US Open in 2012, is looking forward to the challenge of facing the third-seeded Greek.
“Physically, I’ve been good since I’ve been here in the matches,” Murray said Saturday. “I pulled up well the following days after them. That for me has been really positive. I would obviously like my game to be in a better place.
“It is interesting sometimes that you don’t feel like you’re playing particularly well, but I’ve had opportunities in my matches against top players in the past few weeks and not quite taken them. Maybe if I did, I’d be sitting here with a slightly different take on things.”
Murray had a decent run at Wimbledon but was outclassed badly in the third round by Denis Shapovalov.
“Not the easiest draw out there,” Murray said. “When you’re not seeded, these sorts of things can happen. It will be a good, good test for me to see kind of where my game’s at, where it’s progressed to from when I arrived in the States.
“The crowd’s always helped. They like people that fight, give their all, show their heart and emotion and energy on the court. I think over the years here I’ve had very good support, so I’ve enjoyed that.”
Murray’s last win over a Top 20 player came against Alexander Zverev just over a year ago in New York (Cincinnati).
Two seeds Arya Sabalenka and Daniil Medvedev are also on court along with John Isner, Coco Gauff, Garbine Muguruza, Grigor Dimitrov, Nick Kyrgios and Sloane Stephens who faces Madison Keys in a rematch of their 2017 US Open final.
