World number three Rafael Nadal crashed out of the Cincinnati Open after losing in his first match in over a month since withdrawing from his Wimbledon semi-final against Nick Kyrgios. Nadal lost 6-7(9-11), 6-4, 3-6 to Borna Coric in the second-round match. "It's difficult to take a lot of positive things from this match. I need to practice," said Nadal.
