The final match has just been completed, and here are your Sao Paulo Challenger quarterfinal results:
 Ricardo Mello d Juan-Pablo Brzezicki 6-2 6-0
 Federico Delbonis d  Joao Souza 7-6(5) 5-7 6-4
Adrian Menendez-Maceiras d Uladzimir Ignatik 7-6(5) 7-6(1)
[Q] Rafael Camilo d Thomas Fabbiano 6-4 6-4
Save for Ignatik v Menendez, which was not streamed, I was able to watch all of the above matches and will be back with full recaps (and smashingly illustrative screencaps) later on today.
The Delbo-Souza match was… interesting…
