Lorenzi won their only previous meeting. That was in March 2010 on clay and he won in straight sets.
The altitude and thin air help Tomic but this will be a tough match for him. He scraped through against Carballes Baena in 3 sets. Lorenzi is a level above Carballes Baena on clay.
Lorenzi has a poor record against higher ranked players but on clay the losses were against top clay courters.
This could easily go to 3 sets but Tomic needs a poor match from Lorenzi if he is to win.
Value on Lorenzi.
