Thiago Monteiro vs Genaro Alberto Olivieri

Thiago Monteiro would likely be the favorite in this matchup due to his higher ranking, greater experience, and ability to maintain consistent baseline rallies. His movement and court coverage are excellent, and he has been more successful at the ATP level compared to Olivieri, who is still working his way up.

Genaro Alberto Olivieri will likely need to be at his very best in order to challenge Monteiro. He would need to stay consistent, avoid making unforced errors, and find ways to disrupt Monteiro's rhythm. However, without a huge weapon to take the match to Monteiro, he may struggle to keep up with the Brazilian's baseline play.

Thiago Monteiro should win this match, particularly on clay or slower surfaces, where his style is most effective. Olivieri could challenge him at times, but Monteiro's consistency, movement, and experience would give him the edge.
