Like this tuoyo:
The A-button is on the edge side of the racket, not the face side.
As I said though, Federer has wrapped his thumb further around the grip, if you don't need to use the A-button in the game then you could do the same (so if you hold it normally with thumb on a-button, then move your thumb to the left and around to the side of the remote)
