Djokovic commended the efforts of United States Open organizers to keep crowds entertained with music and fan games during breaks in play, but he said he also appreciated the contrasting atmospheres on the tour.

“The U.S. Open does a good job in this way, but of course at Wimbledon, you will never see that,” he said. “The beauty of the sport is also because you have different events that have their own tradition and history that they nurture and respect. Wimbledon, of course, has its tradition that is defining that tournament. You think about Wimbledon, you think about all white, that Centre Court, strawberries and cream, so forth. The U.S. Open is more entertainment, more show.”

Roger Federer, a five-time United States Open champion and a seven-time champion at Wimbledon, said there was far more variability in the crowds he found in New York, which he attributed to Wimbledon having only day sessions.

“The way the people clap at Wimbledon, it’s consistent throughout,” he said. “I’d say if it’s a first set or a final set, it just gets slightly louder. Whereas the U.S. Open I find that there, it’s cool to be at the U.S. Open, cool to watch the U.S. Open, but they’re waiting for something to happen. They won’t start clapping just right off the bat. So you feel there is a little pressure here and there. And then night is electric and really has the potential to go wild. Whereas the day session can go too, but there you need the swings of momentum, the five-set thriller, for the fans to get into it.”

Tomas Berdych, who reached his lone Grand Slam final at Wimbledon in 2010, said he preferred the hushed quiet of that tournament’s Centre Court to the constant hum of Arthur Ashe Stadium at Flushing Meadows.

“Honestly, myself, I prefer the British crowds, London crowds,” he said. “I think it’s very special for tennis. When you stand on the baseline and start to bounce the ball, probably everybody can hear that. And then when you finish the rally, all the people are into it — probably that’s the best feeling in tennis. I’m not saying it’s bad in New York, definitely not. It’s very unique, very special atmosphere, because to play on the stadium where it could be over 20,000 people, it’s not really a daily experience. But they are a bit more loud.”

Berdych, who is No. 5, added that if crowd noise were encouraged between points, players would need more time than the current limit of 20 seconds to let it subside. Time limits between points have been enforced more strictly in recent years to improve pace of play.
