==References needed tag removal== 
 I removed the additional references needed tag. This article seems pretty well sourced now. Tag was added when article only had 6 sources. Now has ~ 33.   

 == Article title change == 
 I think the title of the article should be changed from Oscar Gutierrez to Rey Mysterio. Several other articles on professional wrestlers are titled as their ring name, not their real name, like Rob Van Dam, Tommy Dreamer, and Samoa Joe. Even the article on his uncle, Rey Misterio Sr., is titled as his ring name. More people know him as Rey Mysterio, not Oscar Gutierrez and i think it would be easier for people to find the article if it was titled Rey Mysterio. 
 :If it hasn't been done already, there's gotta be a good reason. Then again, maybe not. Is there a link to a discussion about the page name somewhere or something?
