PARIS — Montreal’s Gabriel Diallo earned his first ever French Open main-draw win with a 7-5, 6-3 6-4 upset of 18th seed Francisco Cerundolo of Argentina in first-round action Monday.

Diallo picked up a big break to go up 4-3 in the third set when Cerundolo committed an unforced error on game point. The Canadian held serve the rest of the way to finish the straight-set win in two hours 10 minutes.

Overall, the 23-year-old Diallo broke Cerundolo four times on 11 chances. Cerundolo, meanwhile, converted the only break point chance he had.

Diallo will next face the winner of a match between Marcos Giron of the United States and Tallon Griekspoor of the Netherlands.
