Wikipedia:Articles for deletion/List of ATP Tour Grand Slam tournaments and Masters singles champions
While this article does have some overlap with section in the other two articles that nominator mentions, I do not think it warrants deletion. This list article serves as a kind of "historic timeline" since 1990, and that overview is not provided by the other two articles. "Timeline of" specialized lists are specifically mentioned here
