CH Santos R1: Arguello def. Souza 7-6(8) 6-1
Souza twice was up a mini-break (one of which was lost on a DF) in the tiebreak. Not a lot of effort shown in the second set, and as the defending champion of this event, Feijao is out of the top 100.
Facu Arguello, though, he's got a lot of game. His forehand is a big shot and he's got a good backhand too. Very impressed by him, he should definitely be an ATP-level player in due time.
