Facundo Mena and Ivan Justo Guido meet in the round of 16 at Buenos Aires 3 on Wednesday. Facundo Mena is rolling — 6 straight wins, 9 of 10 in recent play. Ivan Justo Guido comes in at 5 wins from the last ten.

The serve is where this match separates: Mena has been winning 71.6% of first-serve points to Guido's 63%, and on clay that gap compounds fast. Mena comes in off a compressed schedule. A tiebreak or two would surprise nobody, with Mena fractionally more likely to land the big points.
