Tennis articles

Greetings Rich,

I'd just like to bring to your attention that, on some of the tennis articles, a certain user has been deleting the names of French (Roland Garros) champions, and changing the founding date of the championship. Even though outside sources, such as:

1. ESPN
2. Encylopedia Britannica
3. the Roland Garros website
4. the World Almanac

have supported the inclusion of all French Open winners to 1891, a single solitary user has been deleting the names of pre-1925 champions because it was "not open to international competition"but that's a lie. The very first winner, in 1891, was a British man, and two other British men made it to the final in the 1890s. 

Attempting to rewrite history with Wikipedia is what some people have done, rather than understand that Wikipedia is an encyclopedia.

What do you think I should do next? User Fyunclick has refused to compromise or discuss the issue rationally.
