The court in Arthur Ashe Stadium is not slower than the tournament's other courts, according to the US Open's tournament director.
"We do measurements with our own proprietary tools prior to the tournament, and then again after the tournament," David Brewer told Reuters. "We do that each year, and we’ve done that for about a dozen years now. Our data tells us that the CPR–the Court Pace Rating–is just like any other court on the site right now."
Some players have suggested that the court is slower than in previous years. But court speed also can be affected by the conditions, with cooler-than-usual temperatures in the first week potentially slowing down the ball.
"Players have their own subjective values of any number of things," said Brewer.
The tournament resurfaces the courts each year according to the same standards.
