MADRID (AP) ? Rafael Nadal won his first match on the blue-clay court at Madrid Open, dispatching Nikolay Davydenko 6-2, 6-2 Wednesday.

Nadal had little trouble on the surface that he criticized this week as soft and slippery. The Spanish champion had six aces and 19 winners. He broke his Russian opponent four times to advance to the third round.

American John Isner lost to Marin Cilic 7-6 (4), 7-6 (3). Fifth-seeded David Ferrer advanced after a 7-6 (4), 6-2 win over Radek Stepanek.

In women's competition, defending champion Petra Kvitova exited the tournament after losing to Lucie Hradecka 6-4, 6-3 in the second round.

Li Na defeated Angelique Kerber 7-5, 6-4. Agnieszka Radwanska routed Sara Errani 6-0, 6-1, ending the Italian's 16-match winning streak.
