French No.1 Adrian Mannarino was defeated in the semi-final of the ATP 250 tournament in Dallas (Texas, United States) on Saturday by the American Marcos Giron (6-1, 6-3).

Dominated throughout the match, Mannarino (35 years old, N.17 in the ranking) never found the solution against the 67th player in the world, on hard ground. Giron (30 years old), will have the opportunity to win his first tournament on Sunday in the final against his compatriot Tommy Paul.
