Re: Biggest threat to Serena in Slams?
Of those 3 Kim definitely. She is a possible threat to Serena at any slam if they play except Wimbledon.
I would be surprised if Venus ever beat Serena in a slam again. Even when she was good enough to do it she rarely did since that whole sister thing seemed alot tougher on Venus than Serena. As their dad said Serena is meaner, and Venus had the misfortune of having a blood relative as a main rival with comparable (or superior) talent but a tougher mind for the situation than she did. Now Venus has declined some already and probably isnt even good enough anymore to beat Serena which she had a hard time bearing down to do even when she was.
Wozniacki? No way. She hits almost no winners even against even B-power hitters so against Serena she will almost surely hit almost none. And that means Serena will have a huge margin of error for her high risk game, she will be allowed 40 unforced errors in 2 sets, maybe more, and still be able to win.
I think even Justine is a bigger threat to Serena in future slams than Venus or Wozniacki, even with as much as she struggled this year. She is not turning 30 yet, unlike Wozniacki she has enough offense to hurt Serena if she finds her form, she is not burdened by any sister factor, and she knows she has beaten Serena in slams before- 4 times in fact, so surely knows if she is playing well enough she is quite capable of doing it again. She managed to take Serena to 3 sets in Australia this year despite being far from her best level, which of course she was far from all year long. There is no gaurantee Justine will ever regain her old level, but it still will be alot easier for her to improve on her level of this year than Serena, as her level of this year was so bad for her seemingly the only place it can go is up (and if it doesnt go up from what it was this year she will retire before 2012, I gaurantee it) and Serena isnt likely to go beyond her level in the slams of the last 2 years at this point in her career. Still Kim is definitely a bigger threat to Serena overall than Justine or anyone else right now.
Kuznetsova could be a threat of sorts if she gets her game together again. Last year she had Serena beat in Australia but couldnt close her out, and did beat her at the French last year.
Dementieva has in the past been a tough opponent for Serena, especialy in non slam events, but I dont think Dementieva will ever come close to beating Serena in a slam again.
Jankovic has held her own admirably vs Serena in the past but I think she is now on the downside of her career too.
Stosur hasnt been a threat to Serena on anything but clay yet.
If Petrova catches fire and doesnt choke (yeah right) she could play spoiler for anyone. Barring a miracle she will never win a slam herself but could take out anyone during one, including Serena potentially.
Either way I dont think Wozniacki would beat Serena in a slam other than maybe at the French (and not sure even there) anytime soon. Her game is just too lightweight to do much damage to Serena. And given the whole sister factor in addition to the age factor, I dont think Venus is even one of the most likely threats to Serena either.
