Novak Djokovic has been dumped out of the BNP Paribas Open in Indian Wells by Luca Nardi. Nardi, 20, booked a last-16 meeting with the American Tommy Paul when he beat the world No 1 6-4, 3-6, 6-3. The Italian, currently 123 in the world, is the lowest-ranked player to beat Djokovic at ATP Masters 1000 or grand slam level.
