Disgusting is charitable. He's a waste of space and talent on a tennis court. Even Gulbis would be impressed. I've never seen a player in US Open qualies take such a winnable match and play so disinterested and horribly. Overrated is a generous description of Berankis. Its too bad - he could amount to a lot if he decided to - its up in the air at this point if that ever happens looking at what I saw today.
I must say, I agree with you. His progress has stagnated for a while now, bar the LA run, which was a nice suprise to be honest. He's a hard worker and has talent to do well, but his instability remains his main obstacle, separating him from taking the next step. Maybe it's the mental things - he's ought to be tired of constant injuries and the need to play qualifying. I still believe he has the hunger to succeed and break through, but for now, it's smart for him gather himself, think things through for a while and play in the Challenger Tour, which he'll do. These couple of months will be crucial for him, if he wants to maintain his ranking for next year. I hope he finishes this year in a decent position and starts a fresh year, gets his rhytm going early and solidifies his place in the Tour.
