why the title?

Rating: Null/10 (11 March 2005)

I'm still puzzled as to why it is called "Million Dollar Baby"? There seems to be no reference to it either in the film. What i gathered, however, was that Hillary's character was in a way a baby? to Frankie since his child has abandoned him or vice versa. And the million dollar would come from the money that she had made out of her unfortunately shortened career. I don't know. These are just my reflections. Or did i miss something? I hope someone can offer something concrete because the title is in a way fascinating and somehow odd i felt.on another note, i felt that this film was really an experience for me with its roller coaster of emotions. At the end of it, i was just in awe of it.
