PARIS: Former champion Stan Wawrinka became the oldest French Open semi-finalist in 32 years on Wednesday when he brushed aside Marin Cilic 6-3, 6-3, 6-1.
Swiss third seed Wawrinka, the 2015 title winner, has not lost a set on his way to a third successive semi-final in Paris.
The 32-year-old is the oldest man to make the last four at Roland Garros since Jimmy Connors in 1985.
He will face either world number one Andy Murray for a place in the final.
"It was perfect today, I'm very satisfied," said Wawrinka who will be playing in his third successive Roland Garros semi-final.
"I played well, was very solid and took my opportunities."
Wawrinka, the reigning US Open champion, took his record over Croatian seventh seed Cilic to 12-2 with an eighth successive win over the 28-year-old.
Cilic is still to beat a top five player on clay.
