Indian Wells, Calif. • Top-ranked Novak Djokovic advanced to the semifinals of the BNP Paribas Open with a 6-3, 6-1 victory over Jo-Wilfried Tsonga in 54 minutes on Friday.
Juan Martin del Potro had to go the distance to upset No. 3 seed Andy Murray 6-7 (5), 6-3, 6-1 for the first time in five tries on hard courts and will play Djokovic next. The Argentine has lost to Djokovic eight times in 10 meetings.
No. 8 Caroline Wozniacki outlasted fourth-seeded Angelique Kerber 2-6, 6-4, 7-5 in a 2½-hour semifinal that included 14 service breaks, including seven in the final set. Wozniacki, who won here in 2011, will play either No. 2 Maria Sharapova or No. 13 Maria Kirilenko, who met later.
Djokovic extended his winning streak to 22 matches dating to Oct. 31.
