El Tabakh El of Oakville, Ontario, defeated top-seeded Anastasia Pavlyuchenkova in the first round.
'I'm very satisfied,' said El Tabakh, 22. 'I did a lot better than I thought I would coming into the tournament. I knew (my opponents) were better ranked than I am so I had nothing to lose and I just went for it.'
