Third seed and reigning champion Alexander Zverev was dumped out of the BNP Paribas Open at Indian Wells on Monday by the unseeded Jan-Lennard Struff. In the battle of the two Germans, the 28-year-old world number 55 was in total command, right from the start. It took Struff just 70 minutes to win 6-3, 6-1 - and book a place against Milos Raonic in round four.
