Answer 2

W, L and D are acronyms that refer to Win, Loss and Draw. It is used when showing the MMA Record of a fighter. For ex: If a fighters record in W-L-D is 10-2-1 it means that he was Won 10, Lost 2 and 1 fight was a Draw.

If the fighter has no draws in his record, then only the Win-Loss is shown as W-L.
