"Michelle has demonstrated her outstanding golfing skills to a global audience as both an amateur and now as a professional, and we look forward to welcoming her," said George O'Grady, the chief executive of the European tour - a remarkable volte-face by a man who had previously been sceptical about offering women invitations to play in men's events.
Eight months ago O'Grady dismissed the practice as a "gimmick". But in golf nothing speaks as loudly as sponsorship money. The European Masters is sponsored by Omega and Wie this year signed a sponsorship deal with the watchmakers.
Golf is a game requiring an enormous amount of thought, and unless the player can always ascertain exactly what is the reason for his faults and what is the reason for his method of remedying them, he will never make much progress. The more he thinks out the game for himself the better he will get on.
