Can anyone tell me what grip Federer using on his forehand?

It's a modified Western grip. More like in between a Western and Continental grip than anything. If you watch a slow motion shot of his forehand you'll see that the knuckle of his hand his had is between the 4 and 5 o'clock position on the racket handle for topspin shots. When he flattens it out it at the 3 o'clock position in a Continental grip.

Confused yet?

This should help...

I forgot where I watch it but on the tape, it says that Roger's forehand is the same as Pete Sampras. It's continental in nature.

I found this picture of the grips Federer uses:



According to www.tennis.com, Federer uses a "modified Eastern grip" which "is more conservative than that of most top players, who typically shift farther toward the Western grip and place part or most of their hands under the handle. This grip allows for the ideal contact height for a player who stands close to the baseline and plays the ball early, a key to Federer’s effectiveness."

Did he develop his grip over time or is it the same grip he used in his rookie year?
