Golovkin by KO. Lemieux is a good fighter, but he doesn't have what it takes to beat Golovkin. We know he has some chin issues, they will be brought to the forefront in this fight.
It's not really and interesting fight since Lemieux lost to Rubio and Acline. He manage to put together a streak of wins and manage to get an IBF title along the way but that's where this streak ends. GGG is going to walk him down and stop him within 8 rounds.
