Dementieva in the final of Watson Water (Vaidisova withdrew)
The 15-year-old Vaidisova withdrew from the tournament with gastroenteritis, giving Dementieva an automatic passage to the final.
"I am very disappointed. This was such a good opportunity to compete against so many top players. I really wanted to play, but sadly I just cannot make it," said the teenager, who felt unwell Thursday morning.
