Too bad, Jo.
We clearly aren't used to see him make 60+ UEs. It was mostly a problem of rythm, his movement were off and he couldn't place himself well onto the ball. Congrats to Robredo for exploiting this at maximum by giving him many balls directly on his body or off rythm.
Well, as Turquoise said, it was already a great come back to win two match back to back after a three month injury and a little less than two weeks of training.
We weren't sure before if it was a good idea to rush his come back, even it was for a grand slam, but I think it turns out pretty well and it will give him some confidence for the rest of the year. On the FFT site, he didn't seem really disappointed and he even said that he could have been sent home since the first round if he was faced to a better opponent than Ventura, like Moya or Haas.
Now it's time for you to win your first title on clay at Bucarest.
