And Henri Kontinen doesn't ....?
He played mainly futures - some other youngsters also had significant scores on this level. Helsinki SF, Tampere QF and now Rhodes QF are his best results. Even Tomic won a challenger. Del Bonis won 2 challengers and he's 2 years younger.
But I have no doubt Henkka goes in the right direction, also without as much hype as the others. Plus his style is really great to watch.
