I heard Mary didn't play that well (like at RG or Wim, but there was such a wind today!!!!) but won the important points, that means she played like a champion does when she/he is not in a extremly good day.
I m so happy too , Mary is really back !! it's right that Mary had the occasion to gain the 1st set easily but first there was tourbillonant wind and don't forget she returns from Wimbledon where she has played a lot of difficult match
