WIMBLEDON, England - Random as Grand Slam tournament draws are meant to be, Novak Djokovic and Roger Federer keep bumping into each other in major semifinals, and it could happen again at Wimbledon.
The No. 1-seeded Djokovic, the defending champion, and No. 3 Federer - a six-time winner at the All England Club - were placed in the same half of this year's field Friday. They've played in the semifinals at five of the past seven Grand Slam tournaments, with Djokovic holding a 4-1 edge.
Similarly, No. 2 Rafael Nadal and No. 4 Andy Murray are making a habit of major semifinal meetings. Wimbledon could make the fifth time in nine majors they've played at that stage.
No. 1 Maria Sharapova and No. 6 Serena Williams, four-time Wimbledon champion, could meet only in the final, which would be a rematch of 2004, when Sharapova won her first major title.

Armstrong lawyers file response
Lance Armstrong filed a response to the latest doping allegations against him, accusing the U.S. Anti-Doping Agency of violating its own rules and possibly breaking federal law during its investigation.
In their 11-page document, Armstrong's attorneys complained they still haven't been allowed to see the evidence against him, including witness names and any expert analysis to support USADA's claim that 2009 and 2010 blood tests are "fully consistent" with blood doping.
The letter said USADA's case is "long on stale allegations disproved long ago and short on evidence" and "offensive to any notions of due process."
The agency said Armstrong used performance-enhancing drugs to win the Tour de France from 1999-2005. Friday was the deadline to respond to USADA's warning that charges were pending before the case moves to the next stage.
