Speaking of heat, did you notice that Maria did not have one bit of perspiration anywhere on her face or elsewhere anytime during her matches. I have never seen anyone so completely dry playing such a physical game in the summertime. It was quite amazing.
If you look closely, she has very tiny "peach fuzz type" hair on her face and arms and it was perfectly dry (you should see this real well on your high resolution).
See you at the Open.
OK, this I may have to look up, because I do know they towel off between points. I do that as well on hot days.
If she can't perspire normally, that might not be a great thing.
She was perspiring in several pictures on this site. I saw no massive amounts of it though.
This site is a source of TONS of nice pictures of her, don't know if it is her site, a family members or some great fan, but it was very complete.
