Re: Marin Cilic will be permanent top 10 player
Cilic beat an unseeded player and two wild-cards to make his first slam quarter final. He beat 2 injured players and a 17 year old kid on his way to the Australian Open semi's, taken to five sets in each of those matches.
His only 'back-up' of that lucky-semi has been a quarter final at the USO last year, and apparently he's a perennial top-10 player and possible grand slam champ.
He's won 250 tournaments every year, so the back-injury as an excuse for his meager results in top-tier tournaments means little.
