A spot in the next round is at stake on Monday, when Genaro Alberto Olivieri goes up against Valerio Aboian in the Antofagasta round of 32. Genaro Alberto Olivieri is 4-6 across recent matches. Valerio Aboian is 5-5 across recent matches.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. Little separates them; Olivieri gets the nod on the finest of margins.
