There is a part in naruto anime where the fake madara was talking to the five kages that shows the sage in front of the ten tails, in that part the ten tails had an eye that was like a mixture of the sharingan and the rinnegan and from what has been said so far only the sage and his descendants have his eyes not tailed beasts. So my conclusion is that the sage controlled the ten tails with his ocular powers and he did not fight or beat the ten tails.
