RODDICK HAMMERS DJOKOVIC

Big-serving American Andy Roddick hammered an out-of-sorts Novak Djokovic 6-3 6-2 on Friday to advance to the semi-finals of the ATP event at Indian Wells.

Roddick broke the third-seeded Serb twice in each set to book his place in the last four against world number one Rafael Nadal, who crushed Argentinean Juan Martin Del Potro 6-2 6-4 in a later match.

On a hot afternoon in the California desert, seventh seed Roddick swept through the opening set in just over half an hour on the stadium court at the Indian Wells Tennis Garden.

The second set went with serve until the error-prone Djokovic netted a backhand to be broken in the sixth game and trail 2-4.

World number seven Roddick then held serve before again breaking the Serb in the eighth to reach the semi-finals at Indian Wells for a third time.
