Not to mention, a ring out from getting out of the dimension? Goku's capable of instant transmission between dimensions, and does so frequently. Even between realms of life and death, he can instant transmission.
Hell, even the act of doing it involves Goku making a pocket dimension and instantly wormholing from it to the place he wants to go.
Either way, all of the ways Yuki's been said to win involve completely unshown powers and a fanboyish assumption that she truly has no limits whatsoever, rather than undefined limits. She's never dealt with something like Goku, and he's far enough into that undefined level she never dealt with that he takes her out.
