Jo-Wilfried Tsonga stayed on track for a successful defence of his Open 13 title after a straight-sets victory over Jan-Lennard Struff saw him advance to the final in Marseille.
The Frenchman also won this title in 2009, but Struff made him battle for his hat-trick chance as he took the first set to a tie-break.
World No 10 Tsonga eventually showed his class, though, and prevailed 7-6 (7/4) 7-5.
The 28-year-old will face Ernests Gulbis in Sunday's final, the Latvian having ended hopes of an all-French showdown with victory over Richard Gasquet.
A tight battle was expected between the first and third seeds but in the end it was a relatively simple job for Gulbis as he claimed a 6-3 6-2 win.
"Today was very good," Gulbis told www.atpworldtour.com.
"Everything was working: serve, backhand. I was a bit tired from yesterday, so I just tried to keep the points short and I felt so good doing that."
