Harrison at 17, about to turn 18, has the highest ranking as the French begins, ranked # 264, Tomic is 294 and 3 months younger, and Dimitrov has just turned 19 and is ranked #325. By Peter Lundgren's assessment, and the fact he got to the final round of the U.S. Open qualis two years ago, one would think Dimitrov would be ranked much higher by now. He's got game, his nickname is G-Force, and he plays a facsimile game to Roger Federer, one-handed backhand, beautiful, effortless form, right down to the Nikes. But this year, for example, his best showing is a quarters at the Honolulu Challenger, where he lost in straights to Donald Young, another "can't miss" junior who now's turning 21 and is #149 in the world. So Dimitrov is puzzling. So is Harrison and Tomic to degrees. The former was playing much better earlier in the season where he qualified at both Memphis and Delray Beach, but he just lost deep in the third set in the final round of qualis at the French, and his fast rising has been stalled since the winter. He wants it badly, has a great game, his weaknesses being his quickness, and a serve that sometimes doesn't deliver big blows, and he is America's only male junior chance as of now. Tomic went pretty deep in the Australian Open a couple of years ago at 16, and he is currently in the semis of a Challenger on hard courts in Italy. He's probably not as diverse as Harrison or the athlete Harrison or Dimitrov is, but he might be the most experienced player of the three. I go with Harrison having the brightest career with a top-50 but not top-20 career. Tomic I think will be top-50, too, and so will Dimitrov, but who do you think will be the break out player of this talented, young trio?
