This highly-talented player is repeatedly let down by one facet of her game - the serve. When it cracks, Dementieva serves double fault after double fault - there were 17 in her second-round match here last year. Bizarrely it rarely seems to affect the rest of her game, but the serving problems look set to deny her the opportunity of becoming one of the world's true elite. Has yet to go beyond the fourth round here, but even if she had the Russian simply cannot be backed with any confidence as a result of her serving issues.
