Roger Federer is back at Wimbledon a few weeks after winning his seventh title there, opening his bid for Olympic gold against Colombian Alejandro Falla.
Serena Williams, who also won at the All England Club, plays Jelena Jankovic in the first round. The draw was held Thursday, two days ahead of the event. In the other half of the women's draw, Wimbledon finalist Agnieszka Radwanska of Poland and No. 3 Maria Sharapova could face each other in the penultimate round.
Federer won Olympic gold in doubles in 2008 with fellow Swiss player Stanislas Wawrinka. A medal in singles is the one important accolade to elude him. Second-ranked Novak Djokovic of Serbia was drawn into the same half as Wimbledon finalist Andy Murray, meaning the pair could meet in the semifinals.
