For being Maria's fans, everyone would know that Maria has been wanting to get a gold medal in Olympic, does it affect the world ranking of a tennis player?
Plus, will Maria come to HK for HK Classic?
For a Gold Medal, a player acquires 800 ranking points. These do not expire all at once the next year, I think, but at a rate of 200 per year until the next Olympiad. I assume Silver & Bronze have a lesser point weight, but I dunno what they are.
Far as I know, Maria has not announced intention to play any exhibitions during the winter.
