Jo-Wilfried Tsonga defeated defending champion Nick Kyrgios in the semi-finals of the Open 13 in Marseille, while Milos Raonic is into the final of the Delray Beach Open.
Tsonga, who lifted the trophy in Rotterdam last week, won a hard-fought clash 7-6 (7/5) 2-6 6-4 in two hours and 12 minutes as he closed in on a second consecutive ATP Tour title.
In doing so, he achieved something no player had done before in Marseille - break the Kyrgios serve.
The Australian had the chance to serve out the opening set but could not do so and, although he hit back to level the match, Tsonga gained the crucial break in the third game of the decider.
That guaranteed an all-French final, and Tsonga will face fourth seed Lucas Pouille after he saw off Richard Gasquet 7-5 6-3.
Pouille arrived in Marseille having won just one match all season but has been in fine form on home soil.
Milos Raonic is on course for a ninth career title as he booked his place in the final of the Delray Beach Open in Florida.
The top seed made it through an enthralling encounter with Juan Martin del Potro, winning 6-3 7-6 (8/6).
He will next meet Jack Sock, who came through an all-American semi-final with Donald Young in a 6-4 7-6 (7/2) win.
World number eight Dominic Thiem is into his first final of the year at the Rio Open.
The second seed had little trouble getting past Albert Ramos-Vinolas, winning 6-1 6-4, to set up a showpiece clash with another Spaniard Pablo Carreno Busta.
Carreno Busta ended the fun of teenager Casper Ruud, who enjoyed a breakout week on the Brazilian clay with his first tour wins, with a 2-6 7-5 6-0 win.
