Re: the future of usa tennis ?
Blake has several good years left, but he's 26, so it's hard to call him the future. Roddick had been slumping by his standards, but he's rebounding nicely and playing about as well as he ever has. He won the Masters event in Cincinnati two weeks ago if you didn't notice. He's going to be around for a while.
I think Taylor Dent is capable of having the type of unexpected surge that Blake has had, but he's been injured all year and it's unclear when he'll be healthy again. He's also 25, so like Blake, he's not exactly "the future."
Ginepri and Fish are solid players around the same age as Roddick and Dent. They'll be around for a while, but stars they are not.
19-year-old Sam Querrey has shown much promise. He'll be in the top 100 in no time and in the top 50 probably within the next year. I'm not sure I see star potential though.
17-year-old Donald Young is by far our most accomplished junior, but hasn't fared well against pros thus far. He has many critics who don't think he'll amount to much. Others still see him as a player with big upside.
We seem to have a pretty deep crop of juniors between the ages of 14 and 16, but right now it's hard to say which ones (if any) will emerge as potential stars.
