When Pam Shriver interviewed Coco Vandeweghe on court after the first set of her victory over Sloane Stephens on Monday, it was the first time a player had been questioned during a match, according to ESPN.

It's part of an overall initiative between ESPN and the USTA to make the sport more intimate. ESPN has launched a number of camera and reporting innovations at the Open, across all of its platforms.

Before matches, a player can be asked permission to do in-match interviews but is not required to do so and can back out. In Vandeweghe's 35-second interview, she said she needed to be more aggressive and she came out firing in the second set.

Some players took to social media to question such an interview. Caroline Wozniacki tweeted: "Did I just see Coco do an interview on court, mid match, after the first set?? Surely you would wanna focus on the game out there? No?"

As for Vandeweghe's take on the situation: "Before it happened, I was thinking maybe I might lose focus doing it. But at the same time, we have on-court coaching for WTA events. You could lose focus that way."

And for responses during the interview: "No, I can't remember a thing I said . . . Dead serious. I don't know what she asked."
