Thursday's Lisbon round of 16 pits Andrea Pellegrino against Francesco Passaro on clay. Francesco Passaro brings a 6-match winning streak into this one, 7-3 across the last ten. Andrea Pellegrino is searching for form, having lost 3 in a row (4 of the last 10).

The serve is where this match separates: Passaro has been winning 70.5% of first-serve points to Pellegrino's 65.6%, and on clay that gap compounds fast. This one is close to a coin flip, and the lean toward Passaro is exactly that — a lean.
