World number three Alexander Zverev said he was playing “terrible tennis” after he was knocked out of the Shanghai Masters by France’s Arthur Rinderknech 4-6, 6-3, 6-2 on Monday. The Australian will next meet Portugal’s Nuno Borges, who put an end to the hopes of home favourite Shang Juncheng 7-6 (7/5), 4-6, 6-3.
