Wednesday's Curitiba round of 32 pits Franco Roncadelli against Ivan Justo Guido on clay. Ivan Justo Guido is 5-5 across recent matches. Franco Roncadelli is 6-4 across recent matches.

The serve is where this match separates: Guido has been winning 63% of first-serve points to Roncadelli's 59.1%, and on clay that gap compounds fast. A tiebreak or two would surprise nobody, with Guido fractionally more likely to land the big points.
