Lamasine made his Grand Slam singles and men's doubles debut at the 2014 French Open. He was beaten in the second qualifying round of the men's singles.

He lost in the first round of the singles main draw to 25th seed Viktor Troicki in straight sets. It was his first career singles match in the main draw of an ATP World Tour or Grand Slam tournament.
Lamasine won two singles qualifying matches to reach the singles main draw of the 2016 Swedish Open, but lost in the first round to another qualifier, Calvin Hemery, in three sets. That was his first career singles match in the main draw of a non-Grand Slam ATP World Tour tournament.

At the Lyon Open, Lamasine gained entry to the singles main draw as a lucky loser when Mikhail Kukushkin withdrew due to right shoulder pain.
