Nishikori triumphs in Washington

Novak Djokovic targets second career Grand Slam at Roland Garros

Kei Nishikori will move up to fourth in the ATP rankings after defeating John Isner in a classy 4-6, 6-4, 6-4 come-from-behind victory in the final of the Citi Open on Sunday. 

Isner, who won the BB&T Atlanta Open last week, looked on track to claim his second hard-court title in as many weeks when he broke Nishikori in the 10th game of the opener to take the set 6-4.

Nishikori switched gears after losing the first set, and broke Isner in the opening game of the second set before holding to take a 2-0 lead. At the next changeover, Isner was inspected by the trainer and appeared to be in some pain while having the joint in his right shoulder massaged. However, he was able to return to the court after a short break, only to lose the second set. 

Nishikori broke Isner in the third game of the decider to go 2-1 up, and put in a quality serving performance to ensure he held on to that advantage, winning an impressive 93 percent of points on his own serve as he took the third set 6-4.

The title is the tenth of Nishikori's career and his third of the year, having also triumphed at the ATP Memphis Open in February and the ATP Barcelona Open in April.
