No. 4-seeded Fabio Fognini gained a spot in the quarters by beating Paolo Lorenzi 7-6 (7-5), 5-7, 6-4 in a match that took 2 hours, 42 minutes. Fognini had the only third-set break, which was the difference in the match.
Pablo Carreno-Busta overcame a slow start and defeated Davis Goffin 1-6, 6-2, 6-2.
Fognini is to play Carreno-Busta in the next round.
