Gairy is a good fighter, a top contender. He is only small tho, he is giving up 5 or 6 inches in height to Khan, and his best weight is 130 not 135.
I think St Clair may go the distance with Khan, but he wint hurt Amir cos he is feather fisted.

Khan will probably win a wide UD cos St Clairs best years are well behind him
