PARIS, June 3 (Reuters) - Three things to watch out for on day eight of the French Open on Sunday.
* Day of reckoning for Nishikori?
Leading by two sets to one but trailing 3-0 in the fourth, eighth seed Kei Nishikori was praying for rain by the time his third-round match against 67th-ranked South Korean Chung Hyeon was suspended for the day due to rain.
When they resume on court one, the Japanese faces the prospect of suffering his first tour defeat against another Asian player.
* Waiting for number six
Croatia’s Petra Martic, at 290 the lowest-ranked player to make the third round since 2006, plays her sixth match at this year’s Roland Garros, having battled through the qualifying tournament.
Don’t count her out in her clash with Latvian 17th seed Anastasija Sevastova either. Martic has won 22 of 25 matches since returning from a seven-month layoff due to injury.
* Thiem should be wary of Zeballos
Austria’s sixth-seeded wunderkind Dominic Thiem has been in fine shape at Roland Garros but should beware of Horacio Zeballos in the fourth round.
In the last round, Zeballos advanced after Belgian David Goffin retired after hurting his ankle when he slid into a court cover. In the second round, the Argentine beat Ivo Karlovic, who was seriously affected by a stomach problem.
