Genaro Alberto Olivieri and Pedro Boscardin Dias meet in the round of 16 at Curitiba on Thursday. Pedro Boscardin Dias has won 4 of the last 10. Genaro Alberto Olivieri is 4-6 across recent matches.

Dias's 65.3% behind the first serve (against 61.8% for Olivieri) means break chances should be scarce in one direction. Olivieri comes in off a compressed schedule. A tiebreak or two would surprise nobody, with Dias fractionally more likely to land the big points.
