The King of Clay ruled in this oddest of matches between the best players in tennis.

Rafael Nadal of Spain beat Roger Federer, 7-5, 4-6, 7-6 (10), in an exhibition yesterday in Palma de Mallorca on the Balearic Islands off Spain.

The match on a half-grass, half-clay court was decided when the top-ranked Swiss failed to reach a forehand that took a funny bounce across the green side.

Nadal had gone into the match with a record 72 consecutive wins on clay. Federer has not lost on grass in four years, a 48-match run that includes four straight Wimbledon titles.
