I never heard that. Working on it to improve it doesn't imply being "ashamed" of the status quo.
Wrong on both occasions.
You gotta be shitting me. Grosjean had an amazing serve for his height. He used to be absolutely bomb that ball.
As for the video, go ahead search for "atp worst shots." Gasquet will tell you, it is his serve. If his forehand is bad and he considers his serve his worst shot, oh gosh.
Grosjean had a forehand. And a very good one at that. So it's quite obvious.
what the hell?
