Lucas reached the Round of 16 at the US Open this year. He beat Bemelmans in straight sets in his first round. In his secound round he won his match against Donaldson, a promising young american, after a tough 5 sets battle. In the 3rd round, after a poor start he accelerated to defeat Kukushkin. He lost against Schwartzman in 4 sets in the round of 16. Even if it was a disappointing result in the end, Lucas produced a good level of tennis during the 1st week of the tournament despite his knee injury and achieved his best result in grand slam this season.
