Well, you could do it round by round, or multiple rounds.
But I suggest you just do win, lose or draw. Pretty sure these are the odds they had on Sky Sports News:
Hatton - 1/8
Draw - 33/1
Lazcano - 15/2
I'd suggest making Hatton something like 1/4, as he's not a certainty. Up to you whether you wanna do K/O's. If you do KO's, give both of them higher odds.
