Yoshihito Nishioka booked his place in the French Open fourth round by surviving a five-set encounter with giant-killing Brazilian qualifier Thiago Seyboth Wild on Saturday.
The Japanese 27th seed twice fought back from a set down to claim a 3-6, 7-6(8), 2-6, 6-4, 6-0 victory on Court Simonne-Mathieu in three hours, 38 minutes.
The world No. 172 from Brazil, who made headlines by upsetting second seed Daniil Medvedev in the opening round, took control early on the back of his strong first serve.
Gaining the upper hand as the match progressed, Nishioka won three of his six service breaks in a dominant fifth set.
"I was able to reach the last 16 as a result of not giving up until the end. I am really happy to advance to the fourth round again following the Australian Open," said Nishioka, referring to his previous best Grand Slam result at Melbourne Park in January.
The 27-year-old left-hander, who had never previously been beyond the second round at Roland Garros, becomes just the second Japanese player after Kei Nishikori to reach the last 16 of the tournament since the start of the Open Era in 1968.
