Johnston quite easily. Though I have a bit harsh on O'Grady in the past because he has such an inflated record. He was a pretty good rangey stand up boxer, who wasnt a bad body puncher either. Its just Stevie is better and a hard style for Sean to do well against IMO. He gets past the height with his head movement, skills and awkwardness..and goes to work all night long. Johnston 9-3.
