Yes Lucho will have been looking forward to playing in this tie once the draw was made. His scheduled match against Almagro would have been one of the biggest and most important of his career, had his right arm injury not prevented him from participating in it.
Well done to Silva for making the first 2 sets competitive, against a player ranked 622 places above him. Away from the Davis Cup, Silva has only ever played in one match above futures level, and then came in his home challenger event at Lima which he was granted a wildcard for. However he certainly didn't embarrass himself yesterday.
