New York, Aug 25 (IANS): The world's best tennis players will face one another over the next fortnight with the US Open trophy at stake. On Wednesday evening, however, they banded together for a 'Tennis Plays For Peace' exhibition in support of Ukrainian humanitarian relief.

Rafael Nadal, Iga Swiatek, Coco Gauff, John McEnroe and many more stars thrilled a packed Louis Armstrong Stadium for two hours of tennis to raise money for those suffering in Ukraine, with recently retired Ukrainian players Sergiy Stakhovsky and Olga Savchuk in attendance.

"It has been a very tough couple of years in terms of [the] pandemic, now with the war," Nadal said.

"Excited to be back of course, always a pleasure to play in New York and in front of probably the best crowd of the world."

After an opening ceremony featuring Stakhovsky, Savchuk and host Patrick McEnroe, the Ukrainian national anthem was performed and Nadal took the court for a mixed doubles match alongside Swiatek against Gauff and McEnroe.

"Being on the court with John, Rafa and Iga, World No. 1, it's really crazy here in New York," Gauff said.

"I'm happy that I'm able to do it for this cause and you guys all know me, I like to speak out when it's right. I'm glad that I was able to be a part of this."

Swiatek snuck in a joke about 'Coach Rafa', "On the last point (he) told me that John is going to serve wide and he was wrong. He's wrong sometimes, wow!" she said as Nadal laughed.

Swiatek has previously held her own charity event in support of Ukrainian children. The World No. 1 was happy to spend her time for the cause again.

"I'm pretty happy that we are united and that we as public persons and athletes are doing so much. For sure the event that I did in Poland was a great experience for me. That was the first event that gained so much attention in tennis in Poland," Swiatek said.

"I'm pretty happy that we raised so much money for kids in Ukraine, mostly because their lives have changed and it's right next to my country, so I was pretty emotional and pretty happy that I can use my sport that way and that we're doing this today. It's great."

McEnroe, who also ironically spent time as the chair umpire later in the event, grew up 15 minutes from Flushing Meadows. The former World No. 1 thanked the crowd for their support.

"I just want to say for this event, we're all a fraternity, the tennis players. We're pulling for each other," McEnroe reflected. "Obviously we all want peace and hopefully this will do something towards helping the situation over in Ukraine."
