Monday's San Marino round of 32 pits Daniel Rincon against Juan Carlos Prado Angelo on clay. Daniel Rincon is 6-4 across recent matches. Juan Carlos Prado Angelo is 3-7 across recent matches.
The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.
On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. Little separates them; Rincon gets the nod on the finest of margins.
