Paris - Rafael Nadal takes a 10-0 French Open semi-final record into his match up at Roland Garros against 2009 US Open champion Juan Martin del Potro.
Nadal is closing in on his record-extending 11th title at the clay-court Grand Slam tournament and what would be his 17th major trophy in all.
Del Potro is playing in the French Open semi-finals for the first time in nine years.
The other men's match is No. 7 Dominic Thiem of Austria against unseeded Marco Cecchinato (cheh-key-NAH'-toe) of Italy.
Thiem is appearing in the final four at Roland Garros for the third consecutive time.
Cecchinato had never won a Grand Slam match until this tournament. At No 72, he is the lowest-ranked French Open semi-finalist since 1999.
In 2016, Cecchinato was accused of match-fixing but an 18-month suspension was thrown out on a technicality.
