It's not good preparation but I have more days for getting ready for Wimbledon

Petra Kvitova Defending Wimbledon women's champion

"You know, I didn't necessarily play badly in the first set. It's just that I wasn't patient enough in the rally, and I let her [Sanchez] dictate points."

Victory for Watson set up a second-round match with Czech number seven seed Lucie Safarova, who beat Hungary's Timea Babos 3-6 6-3 7-6 (8-6).

Asked if it was a good day for the British contenders, Watson said: "Yeah, brilliant day. I didn't see any of Laura's match, but she did really well to come through. That's a tough first-round win.

"I'm also very pleased with myself to get through there."

After her defeat, Kvitova admitted she needed to improve ahead of the start of Wimbledon on 25 June.

"It's not good preparation but I have more days for getting ready for Wimbledon," she said. "I have to work hard now to improve my game."

World number seven Wozniacki was watched by her boyfriend Rory McIlroy as she lost to American McHale despite saving three match points.

Wozniacki said: "I would have liked to have won that match, but at least I got some points in. I'm just trying to work on a few things before Wimbledon."

Meanwhile, 2011 champion Marion Bartoli enjoyed a smooth passage into the second round, the French player easing past Sorana Cirstea 6-2 6-2.

The top seed also fell in the men's event, with Frenchman Richard Gasquet losing 1-6 7-6 (7-5) 7-6 (7-3) to Australia's world number 82 Marinko Matosevic in the second round.

In the first round, Andy Roddick claimed his first win in seven matches as fellow American Sam Querrey retired with an injury when trailing 5-2.

Britain's Jamie Murray teamed up again with American Eric Butorac , his early-career partner, in the men's doubles, but they were beaten 7-6 (12-10) 6-2 by the Italian pair Daniele Bracciali and Andreas Seppi.

But Dominic Inglot and Jonathan Marray did better for Britain, beating Spanish second seeds Marcel Granollers and Marc Lopez 6-3 6-3.

Fellow Britons Colin Fleming and Ross Hutchins , the number three seeds, beat Australia's Paul Hanley and Austria's Julian Knowle 6-3 6-4.
