World number one Annika Sorenstam, who pulled out of the Canadian Open with exhaustion three weeks ago, says she is physically fit but emotionally drained going into this week's British Open.

The tournament, which begins tomorrow, is the last of the year's four women's major championships, and the only one not yet clinched by the 32-year-old Swede.

"I'm pretty close to feeling 100 per cent physically, but emotionally and psychologically, I'm still not quite there," Sorenstam said yesterday.

"But I am more rested than I was before the US Open (earlier this month). At least my brain is now on golf."

Sorenstam claimed her fifth major, the LPGA Championship, last month.
