A lot of people think Muray played poorly but this clearly isn't the case. It was his concentration that let him down. He had the chances, he converted alot of them, but holding onto breaks requires concentration and he didn't have any. He played well and got into good positions but his concentration failed him.
Had his concentration been better he'd have won 6-3 6-4 6-1 or something. He was up a break in set 1, 2 and 4 and had 15-40 at 4-4 in the first. He's definetely playing well enoguh though.
