I couldn't see the match entirely for the Spanish TV changed over to Dolgopolov-Nadal once it started
but I could see the first set and for me it was an impresive performance by Ferrer.
His ROS are superb and allows him to grasp some opportunities at return games. I think we should keep in mind that Rosol is +20cm higher than Ferrer and so he is expected to dictate points, anyway that is not what happened. Come on: Ferrer even made 5 aces for Rosol's nil (0) and I'm not sure (can't find it in the stats) but he might as well have done more winners.
Granted Rosol has more power but surely it's not even his merit for he has more leverage.
