Federer on mid-match interviews: 'I haven't done it in 17 years, so why start now?'

It's too early to tell whether the groundbreaking interview CoCo Vandeweghe did with ESPN between sets of her first-round US Open match Monday was a one-off or a sign of things to come.

One thing that seems certain, though, is that Roger Federer doesn't plan to give many interviews of the like in the future.

"I understand the idea, but what's too much? What's enough?" Federer said in his post-match news conference Tuesday after thumping Leonardo Mayer in the first round. "I understand pushing the boundaries and being more accessible. For me, in some ways it's - I haven't done it in 17 years, so why start now?"

Federer has made his legendary career out of pushing boundaries on the court - a practice he maintains to this day - but apparently he's not yet willing to do the same for the world of broadcasting - though he did seem to momentarily ponder the possibility.

"At the same time, you might think, Who cares, you know? Honestly I think I'm pretty relaxed when I'm sitting there at the change of ends. But you don't want it to impact your game and you don't want to look back and think, What a stupid move that was in hindsight, you know. Then you're frustrated about it. So I don't know. I understand the request, but I'm not sure if many players are actually doing it."
