I wouldn't underrate Rose in this matchup. For one, 118 wasn't Fenech's ideal weight. He really peaked at 122-126. And the way Rose dismantled Rocky Gattelari and outclassed Harada was just masterful stuff. Boxing that I don't think the tight Fenech would be able to handle at bantam.
I like Rose but also have Fenech taking a decision. I rate Fenech highly H2H and don’t pick against him H2H very often.
