Tommy Robredo didn't have enough to troble a revived Canas.
Back on the ATP Tour after serving a 15 month drugs suspension, Canas had eight break points in the opening set and could not convert any of them but prevailed in the tiebreak 7-5.
The Argentine then pounced on the dejected Spaniard, sweeping through the opening four games of the second set to take control of the match.
