French teenager Gael Monfils reached his third ATP final with a 6-4 7-5 victory over compatriot Sebastien Grosjean in the Lyon Grand Prix.
The unseeded 19-year-old will now meet top seed Andy Roddick after the American stopped an all-French final by beating Fabrice Santoro 6-4 7-6.
Monfils proved solid enough on the baseline to break Grosjean's serve once and wrap up the first set.
Grosjean hit back to lead 4-1 in the second but Monfils dug deep to prevail.
"I started to fight on every point as I had the feeling he felt tired," the young world number 36 said.
"I played a little better than he did and I was a bit more lucky in my strikes too.
"This is my third final this season and I'm really happy as it's certainly the most important one for me."
After winning through, Roddick predicted a close-fought final with Monfils.
"It will be tough. Monfils plays just like me," Roddick
said. "The first time I saw his serve I thought I was
looking in the mirror with the motion he has."
