Angulo by fairly easy stoppage inside 4 rounds. Vanes is a B level fighter, with mediocre skills. If I were to pick an exact round I'd say round two, I just think Vanes' ability and prospects are not good at all, Angulo will overwhelm him, smother him, and will ultimately crush Vanes brutally.
Erislandy Lara by TKO 11. Dzinzurik is a decent fighter, while Lara is a very good fighter, Lara's footwork and counterpunching will shut Sergei down.
