With so many hard hitters on court but a slow surface, all four protagonists had to change their approach and look for control and finesse over power. The first break went to Mieres and Lamperti in the fifth game. But they didn't enjoy their advantage for too long because Diaz and Lebron regained what they lost to make it 3-3. Controlling the number of unforced errors turned out to be key at the end of the first set and it was Mieres and Lamperti who broke in the ninth game and won 6-4. The two Juans responded quickly with a break in the second game of the second set. They upped their quality and went up 3-0 but were brough back to 3-2. They sprinted away again and won 6-3 to force a deciding set. No one made any inroads until the seventh game, when Lebron exploded onto the scene, backed up by a majestic Juan Martin Diaz, and made it 4-3. Diaz and Lebron celebrated their return as a pairing with a 6-4 scoreline that qualifies them for the semifinals.
