Serve position

Another nice image to keep in my head. Look at how compact he is.

Serve: Fed vs Grosjean

I stumbled across this photo of some player (turned out to be Grosjean) and wondered what looked different from Federer. Couple things I can see:

• Fed's head is farther back, chin towards the ball, Grosjean's is leaning into the shoulder
• Fed's tossing arm and racket form a triangle, Grosjean's diverge
• Fed's wrist is pronated a bit more
• Fed's racket is closer to his head
• Fed's tossing arm is relaxed and slightly bent

Fed's backhand

Notice:

• Wide step
• Shoulder rotation: 45º or so to the net
• Chin over the right shoulder
• Hitting arm tucked into the body
  
• Wrist laid back
• Racket behind head, facing up and towards the side fence, 45º or so
