INDIAN WELLS, Calif., March 15 (UPI) -- Novak Djokovic
remained unbeaten in 2013 Friday, rolling into the semifinals of the BNP Paribas Open with a 6-3, 6-1 victory over Jo-Wilfried Tsonga.
Juan Martin del Potro then surprised Andy Murray to earn a chance against Djokovic, the world's No. 1 player and the dominant figure in the game since the start of the 2011 season.
Djokovic has won his first 17 matches this year and has a 22-match winning streak working from last October. He still has a long way to go, however, to equal the 43-match win streak he put together to begin the 2011 campaign.
He needed just 54 minutes to dispose of Tsonga, who lost to Djokovic for the ninth straight time.
Djokovic has two championships to his credit this year, including the Australian Open -- his sixth major title.
Del Potro ousted the third-seeded Murray 6-7 (6-8), 6-3, 6-1, downing the 2012 Olympic champion for only the second time in their seven confrontations.
Saturday's other semifinal will send Rafael Nadal against Tomas Berdych. Nadal owns a 12-3 record against Berdych, including a win in the 2010 championship match at Wimbledon.
