I think Mauresmo has the best scheduling on the tour. More than the williams, less than the belgians. Even when she isn't injured she always seems to pace herself well. Capriati also does the same. Amazing how well she (momo) maintains her ranking despite injuries.
I saw her in Fed Cup last week. She played OK, not her best but at least she didn't seem to have any physical problem. Her backhand didn't work particularly well in her first match, but in the second one it was much better.
From what I saw, she could be playing any tournament before Toronto if she wanted.
