Devin was in better shape than Tomic.
How can you say that he was in better form than Tomic ?
He has just accumulated defeats in the futures circuit
Tomic won two challengers and two slam first rounds
In his US generation, Domijan, Buchanan, even Rhyne Williams have been ranked in the top-800. Britton has never entered the top-1000, which is really not much at his age (he's more than one year older than Tomic)
