Kei Nishikori outlasted rising South Korean Chung Hyeon in five sets on Sunday to advance to the French Open round of 16 for the third straight year.
In a match that started on Saturday before being suspended by rain, eighth seed and world No. 9 Nishikori downed the 67th-ranked Chung 7-5, 6-4, 6-7 (4-7), 0-6, 6-4.
His next opponent will be Spanish veteran Fernando Verdasco. Nishikori is 3-2 in his career against the 33-year-old Spaniard, but hasn't lost to him since 2012.
