Novak Djokovic reaches Indian Wells semifinals via walkover (Yahoo Sports)

Novak Djokovic didn’t have to hit a ball to get into the semifinals of the BNP Paribas Open on Thursday when opponent Bernard Tomic withdrew because of a back injury. Tomic’s withdrawal was announced about five hours before he was to play the top-ranked Djokovic, a three-time champion at Indian Wells who won his first three matches in straight sets. Djokovic’s semifinal opponent on Saturday will be fourth-seeded Andy Murray, who defeated No. 12 seed Feliciano Lopez 6-3, 6-4 for his 497th career victory.
