I know he's played in windier conditions - in a gale even at the USO - but it seemed to be coming in sudden gusts, and even the comms mentioned it. I didn't get the impression that Andy was using it as an excuse.
It's an excuse in the sense that he didn't think Berankis would play at that level. He has credited him quite a bit but Andy looked slightly rattled at times and was not at his best. He probably thought his average game would sort Beraknis out but that wasn't the case. And we' saw the match too and the wind should have troubled both. It didn't trouble Berankis and he doesn't have a high toss ball. Anyway, Andy got himself out of trouble and that's more important.
