I think there is a 20% chance for Anne to win this. It's not much but as long as it's not 0%, let's cheer for her.
And no, I didn't use any mathematical formulae to work that percentage out, it's purely instinct. There's nothing to suggest Anne cannot win at all, but in my eyes, Elena is obviously the more complete player. Her first round match sounded like a shocker but whatever pulled her through is obviously going to trouble Anne immensely. I'd be happy if Anne made the scoreline respectable and kept her on her toes.
Amanmuradova troubled Dementieva as she had a massive serve, serve/volleyed a bit, and showed some excellent touch at the net, barely missing a volley.
Anne isn't going to be able to trouble Dementieva by using the same tactics though, as she simply doesn't have that in her game.
20% chance of winning.... I'd take Dementieva at 1/5 to win the match, considering she's around 1/18 at most bookies!!!
Although Dementieva is prone to the odd wobble, I've not seen anything from Anne that suggests she can beat a top 5 player - I think those thinking she can win have gone carried away a little bit... (she was losing to Osterloh a week ago, ranked 170ish and well past her best) but she does have a very small chance of winning, and I would be delighted if she did win the match, but I just can't see it happening
I'm predicting Anne to play well for spells, striking quite a few superb winners but serving below 60% and finding her second serve getting destroyed (she'll do well to win more than 35% on 2nd). While she has some weapons, I doubt she'll be consistent enough to be competitive; a few too many decent shots flying just long or narrowly wide. Something like 6-4 6-2. Getting a set would be amazing.
Matt Cronin's take on the match up from US Open website (apologies if already posted):
"5-ELENA DEMENTIEVA V. ANNE KEOTHAVONG
How pleasant it is to have a British woman back in the mix. It's been quite some time since the birthplace of tennis has helped produce a player with top-30 stuff, and the hard-working Keothavong has the potential to move forward if she keeps improving her all-around game. She's a good mover with decent weapons from the backcourt who on a great day can be relentless.
But she's met her match here, as Dementieva defines the tireless, put-up-your-dukes-and-go-15-rounds type of competitor. She's playing free and easy after her Olympic gold-medal run, and she rarely gets tight after significant tournament runs. The only way that Britain's top player can pull an upset here if Dementieva loses her head, and it's way to early in the tournament for that. The Russian will win in straight sets."
Just isn't going to happen to Anne, just as expected really.
She seems to be struggling to hold each time, while not really getting a look at breaking, and it just looks like the fact Dementieva is a much better player is going to tell at the moment
