Man arrested for kissing victorious Nadal

A man was arrested at the US Open after running on the court at Arthur Ashe Stadium to kiss Rafael Nadal following his victory last night.

Tournament spokesman Tim Curry said police arrested the man for interference with a sporting event.

"We're reviewing what happened and then will determine if we have to make any changes to our on-court security procedures," Curry said.

When Nadal completed his win over Frenchman Gael Monfils, the spectator ran out of the stands and approached the Spanish star on the sideline before security guards intervened. It's the latest in a series of similar episodes at major tennis events, including when a man went up to Roger Federer during the French Open final and tried to place a hat on his head.

"For me, it wasn't a problem. The guy was really nice," Nadal said. "He said, 'I love you,' and he kissed me."

During the match, Nadal survived an early scare against Monfils before marching to a 6-7 6-3 6-1 6-3 victory.

Monfils played some extraordinary tennis to take the opening set but Nadal looked back to his best as he left the French 13th seed in his slipstream on the floodlit court.

Nadal suffered a blip when he was broken in the fourth set to allow Monfils to level at 3-3 but he struck back to claim victory in two hours 45 minutes.

Victory combined with Andy Murray's defeat earlier in the day means Nadal, who faces Fernando Gonzalez in the last eight, returns to number two in the rankings.
