The Baby Bull couldn't pivot his way out of this beating. O'Grady probably stops him in the middle rounds. Diaz's best chance is a stoppage on cuts.
Fun match up. I don't think Diaz has the power to trouble Sean O'Grady. O'Grady was also a very good puncher and had a great body attack and I reckon that would be enough for me to favor him against Diaz by late stoppage.
