Borna Coric spoiled Rafael Nadal's return to the Western & Southern Open with a 7-6 (11-9), 4-6, 6-3 upset in the second round on Wednesday.
The 36-year-old Spaniard, who won the title in Cincinnati in 2013, was playing his first match in well over a month after withdrawing from his Wimbledon semifinal against Nick Kyrgios with an abdominal injury.
"When you come back from injury, if you win the first match things get better," Nadal said. "That was not the case today."
