I really like Denis, but I don't think he is one to look out for. His results have been very inconsistent, with a tendency to record a few really bad losses. He also lacks power, which will prevent him from making it to the Top 20.
There are a bunch of guys who are making (small) strides in the Challenger and Futures circuit right now. US tennis certainly looks more promising than the last five years or so, but I'm not sure whether there are any breakaway stars.
