The following is from her website : I want all my fans to know that the WTA Tour is forcing me and several of the other top players to do a 4 hour commercial shoot for WTA Tour marketing materials. They want me to do this shoot on Sunday, Monday or Tuesday of the Rome tournament after flying 12 hours from LA. I have set my own personal rules when is comes to doing shoots and I never do shoots before tournaments because they are mentally draining and I want to just focus on my tennis.

For Maria Sharapova, doing photo shoots is mentally taxing and she only wants to concentrate on tennis. It is unreasonable for the WTA to require their players to participate in the shoot in a date so near the tournament.
