World No 1 Caroline Wozniacki showed no respect for her elders at the French Open on Monday, crushing Japan's Kimiko Date-Krumm - a woman twice her age - 6-0, 6-2 in the first round.

Top-seeded Wozniacki, 20, took just 60 minutes to dispose of the 40-year-old Date-Krumm and will now face her near-namesake Aleksandra Wozniak of Canada for a place in the last 32.

"It was a good start to the tournament for me," said Wozniacki.

"The last time I played Kimiko it was a bit of a longer match, at Wimbledon (in 2009, when Wozniacki won 5-7, 6-3, 6-1).

"She plays a different kind of tennis so it was difficult to play as I wanted to. But a win is a win, so I'm happy to be through to the next round. Physically, I'm feeling good and ready to play this tournament."

The Danish star, who won her fourth title of 2011 in Brussels last week, is bidding to go beyond the French Open quarterfinals for the first time, having lost to eventual champion Francesca Schiavone in the last eight last year.
