It is the fourth time in seven years an all-French team is through to the men’s doubles final in Paris.
In what could have been a Tokyo 2020 Olympic semi-final line-up, the French beat the Colombians, and Germans Krawietz and Mies saw off Argentine pair Guido Pella and Diego Schwartzman 7-5, 6-3.
Kristina Mladenovic had the chance to assume the world No.1 women’s doubles ranking had Belgian Elise Mertens and Belarusian Aryna Sabalenka lost their quarter-final.
But Mertens and Sabalenka proved too strong for Lyudmyla Kichenok and Jelena Ostapenko 7-5, 6-2, ensuring Mertens would hold onto top spot.
The sixth seeds complete the women’s doubles semi-final line-up and will face second seeds Timea Babos and Mladenovic for a place in the final.

Dabrowski and Pavic narrowly held off Nadia Kichenok and Aisam Ul Haq Qureshi 6-7(4), 6-1, [10-8].
