It's worth repeating Jonathan Overend's (BBC correspondent) analysis of Heather Watson's match today.
"With the exception of one poor game in the second set, for which she can surely be excused, this was an excellent performance from Watson. She served and returned superbly and moved around the clay court like a seasoned pro. A technical change to her service motion has given her more bite, especially on the first delivery on which she didn't lose a single point in a dominant first set. Her beaming smile, as she left the court, illuminated this little corner of western Paris. Back in "happy land". "
