King of clay
, 7-5, 4-6, 7-6 (10), in an exhibition yesterday on a half-grass, half-clay court in Palma De Mallorca, Balearic Islands, when the top-ranked Swiss player failed to reach a forehand that took a funny bounce across the green side.
"We're used to playing long, hard games with a lot of tension involved," Federer said. "So it's fun to play on this half-grass, half-clay surface."
Nadal came into the match with a record 72 straight wins on clay. Federer hasn't lost on grass in 4 years - a 48-match run that includes four straight Wimbledon titles.
"It was a long match, with many changes of pace and with little time to adapt," Nadal said. "My feet are suffering as a price of having to adapt to the grass."
Federer was leading 4-1 in the tiebreaker before Nadal rallied. After the Spaniard double-faulted while ahead 6-5, the players traded match points. Nadal then hit three of the final four winners from the clay side in front of a sellout crowd of about 7,000.
"It was a fun way to pass 2 1/2 hours," Nadal said.
