The fourth-seeded Spaniard, whose season didn't start until February when he returned from a seven-month injury absence, proved again the eight-time French Open champion is back in peak form after his shock first round exit at Wimbledon.

He beat unseeded American John Isner 7-6 (10/8), 7-6 (7/3) to add the Cincinnati crown to the Montreal Masters title he won a week before, his first ever back-to-back hardcourt trophies.
