Grosjean is known for his extreme forehand, his best shot, he utilizes something of a western grip, which is hit at high velocities.

This was long considered the worst 'choke' in five-set history,[citation needed] until the 2004 French Open final.

He also won the doubles final with Jo-Wilfried Tsonga as a wildcard team, where they upset the first and third seeds.

Considered one of the more popular players on the circuit, he is lauded for his attractive, graceful style and classical skills.

The family resides in Boca Raton, Florida (U.S.), where Grosjean trains at the Evert Tennis Academy.

He used the Head Radical Tour TwinTube 630 XL under various paint jobs throughout his career.
