MANILA, Philippines – World No. 1 Rafael Nadal and world No. 2 Novak Djokovic played an exhibition match on board a ferry outfitted with a tennis court as it sailed near the famous Perito Moreno glacier in Argentina. The match, called “Tennis on Ancient Ice,” was sponsored by Argentina’s Ministry of Tourism. After the event, Nadal said it was one of the most spectacular places he’s ever seen. Nadal and Djokovic are on a South American exhibition tour and played with Argentine tennis star David Nalbandian over the weekend to mark his retirement. -- Mornings @ ANC, November 26, 2013.
