LONDON — Seven-time champion Roger Federer could face Rafael Nadal in the quarterfinals at Wimbledon — their earliest meeting in any Grand Slam.

The draw Friday for the grass-court Grand Slam placed the third-seeded Federer and No. 5 Nadal in the same half. Federer is the defending champion at the All England Club, while Nadal is a two-time winner.

Home favorite Andy Murray, who is seeded No. 2, is also in the same bottom half and could meet Nadal or Federer in the semifinal. Top-seeded Novak Djokovic is in the top half and has a much easier path to the final, facing a possible semifinal against No. 4 David Ferrer.

In the women’s draw, five-time champion and top-seeded Serena Williams will open against Mandy Minella of Luxembourg.
