Serena Williams admits looking up to Federer

NEW YORK – Successful as she is in her own right, even Serena Williams relishes a chance to get an up-close look at Roger Federer on a tennis court.

When they practice near each other, Williams — owner of 21 Grand Slam singles titles — takes a peek at what Federer — owner of 17 — is doing.

"I'm always looking over: 'What is he doing?' Giving him the side eye. 'OK, maybe I should do that. I should do that. Oh, he's taking a break now,'" Williams said after moving into the second round of the US Open on Monday night (Tuesday in Manila).

"It's super distracting," Williams added. "I totally look at him. I mean, he's Roger."
