World No 1 Novak Djokovic, stunned by Juan Martin del Potro in the ATP Indian Wells Masters semifinals on Saturday, wasted no time mourning the end of his 22-match winning streak.

The dominant player in men's tennis immediately turned his attention to Miami, where the second ATP Masters event of the season will start next week.

"It's sport," Djokovic said of the end of a streak that had stretched back to Oct 31. "Now I need a few days off and I'll move on to Miami."
