Aravene Rezai is very very impressive at US Open
I have been going to USO all week and checked out a lot of "newcomers" that I have not seen live before. Among them, Rezai impressed me more than anyone else. Her groundstrokes, both forehand and backhand, are powerful and relatively error-free. Her serve is good, too. Not to mention her composure and agressiveness. I say potential top 10 material.
Her last match with Kirilenko was flawless, reminding me of Shuai Peng when she defeated Clijsters in straight sets in San Diego. The only question is whether she can keep that level of intensity going.
I think she has an excellent chance to take out Dementieva. From there, a very good chance to reach SF since Jankovic/Sveta are even less dangerous than LenaD. Seriously I have the feeling she could be the darkest dark horse at US Open in years, but don't want to say too much at this point so as not to jinx her.
I was also impressed by Vika Azarenka and Aga Radwanska in different ways, but more to that later.
