Monday night's exhibition tennis match between Rafael Nadal and Juan Martin del Potro at Madison Square Garden took an entertaining twist when Ben Stiller came out of the stands, picked up a racket and went on Nadal's side of the net.

Not to be outdone, or shorthanded, Del Potro called a young girl out of the stands to even up the sides. The girl, 9-year-old Rebecca Suarez of Huntington, showed that she has game. What was left of the crowd originally estimated at about 15,000 went crazy as Suarez knocked about three or four shots over the net.
