MC creates an alias to help the girl

[sherlockholmes950527]

MC is a nerd and is in love with a cheerleader. She is worried about getting a scholarship through cheer leading. MC creates an alias (Mr.x or something) to help their sport teams with strategies and they work out well.
He becomes a successful doctor. And there is a "guess Mr. X's real name" kind of game played for their school reunion too.

Tried search and got tired. So here I'm, looking for the story in the right place. Thanks in advance

(Was it too messed up?)

This is probably "Mr E. (Over The Top)" by double_entendre.
