The field of play is getting narrower at Wimbledon. Monday, two U-S favorites were knocked out on the women's side. It is the first time in five years that neither Serena nor Venus Williams will play in the quarter finals.
On the men's side, six-time champion Roger Federer has earned a berth in the Wimbledon quarter finals with a four set victory over 18th-seeded Mikhail Youzhny.
The ladies quarter finals begin bright and early Tuesday morning at 7, while the men return to play Wednesday at the same time.
