This is the first meeting for all the above-listed competitors, which the exception of:
Fernando Romboli vs.  Ricardo Hocevar: Hocevar won their only previous match 6-1 3-6 7-6(2) in April. Romboli has stated he’s playing better than ever, and their last meeting was a close one, so…
Rodrigo Guidolin vs.  Guillermo Alcaide: Guidolin won their only previous match 6-3 6-4 in the ’09 qualies of the Belo Horizonte Challenger.
Fabiano vs.  Fabbiano: they’ve never met, I just wanted to point out their names.
Will post results as I get them. Assuming I haven’t gone back to bed, that is.
Update: Darn it! I’m always wrong with my elliptical insinuations… Ricardo Hocevar ends Fernando Romboli’s 11-match winning streak 7-5 4-6 6-1. Seems like Fernando might have run out of gas in that third set. And who could blame him? Back-to-back-to-back tournaments over 2.5 weeks of winning, seeing his ranking rise 61 spots to #287. It was a good run, and I’m designating Fernando Romboli an official Player to Watch as of this sentence. Congrats on your excellent streak, champ!
Other results: Andre Ghem upset  Silva 7-5 2-6 6-2 and will face  Zampieri, who beat Almeida 6-4 6-4. Translated article here.
