Italian teenager Lorenzo Musetti defeated compatriot Marco Cecchinato in five sets Saturday to reach the French Open last 16 on his Grand Slam debut, setting up a potential clash with Novak Djokovic. The 19-year-old Musetti overcame 2018 Roland Garros semi-finalist Cecchinato 3-6, 6-4, 6-3, 3-6, 6-3 after taking his fifth match point to become only the sixth man since 2000 to make the last 16 at his first major. mw/dj
