PARIS — Caroline Wozniacki beat the heat and an overmatched opponent Monday in the first round at the French Open.

With temperatures headed into the mid-80s on a second successive cloudless day in Paris, the No. 3-seeded Wozniacki had a morning match on center court and needed barely an hour to dispatch Alla Kudryavtseva 6-0, 6-3.

Wozniacki has played the most tennis of anyone on the women's tour since the start of last year, and she looked sharp, committing only nine unforced errors and missing just 11 first serves. Kudryavtseva lost the first seven games, then won two in a row, but she was unable to stay with Wozniacki in long rallies.

Kudryavtseva changed rackets before the final point, but it was too late. Wozniacki closed out the victory with a service winner, then blew kisses to the crowd.

The women's draw is considered wide open, with Wozniacki among the title contenders. The 19-year-old Dane was the runner-up at last year's U.S. Open to Kim Clijsters and has a 29-12 career record in Grand Slam tournaments.

No. 24 Lucie Safarova also worked quickly, beating Jelena Dokic 6-2, 6-2.

On Sunday, Venus Williams looked sure-footed on the surface that has vexed her more than any other while defeating Patty Schnyder 6-3, 6-3.
