No. 7 Roddick’s game was solid all-around against No. 3 Djokovic. The error-prone Serbian made 30 unforced errors, 18 more than his American opponent.
The semifinals appearance will be Roddick’s third at Indian Wells. He lost to Lleyton Hewitt in 2005 and to Rafael Nadal in 2007.
Off to a career-best 23-3 start this season, Roddick next faces the winner of the quarterfinal between No. 1 Nadal and No. 6 Juan Martin del Potro.
Vera Zvonareva defeated Victoria Azarenka 6-3, 6-3 to gain the women’s final.
No. 6 Zvonareva, a 24-year-old from Moscow, made it to the championship for the first time in five appearances at Indian Wells. She previously had advanced as far as the quarterfinals in the event three times, including last year when she lost to eventual champion Ana Ivanovic.
The 19-year-old Azarenka, from Belarus, lost for only the second time in 19 matches this year. Zvonareva improved to an identical 17-2 for 2009.
