Sarah is the senior woman here, but I understand she practices some martial arts so would have some advantage over Selena and Vanessa. Hayden should have a much closer fights with both the brunettes, but Sarah will help her get the win. I'd say the same if it was Selena or Vanessa on Gellar's side as well. Neither girl has a superior size & weight advantage, so it all comes down to Sarah handing out the ultimate punishment.
