I saw the match yesterday - Ferrer was in control up to 6-4, 4-2, lost his focus, but then played better again in the third. With him only playing two matches in over a month, I think he's just a bit rusty. Mentally he was a lot better than in Barcelona. Roger-Vasselin played well though - Andy was impressive in their match, just a shame he had to face Stan in the next round.
I don't think Ferrer's recent performances are due to age-related decline as such but more to do with tiredness. He played more matches than anyone in 2012 and has had a packed schedule so far this year. Perhaps missing Monte Carlo and losing early in Barcelona might help him in the long run.
His scheduling is really quite abysmal. He really can't afford to grind out a dozen 250 events, especially at his age, if he wants to stay fresh for the bigger tournaments.
Gastao Elias will break the top 100 soon. Another one to keep an eye on. Into QFs in Oeiras.
