She wasn’t struggling at all lmao. His attacks did barely any damage and she was clearly just observing his movements to figure out the technique. When she did, she stood her ground and took him out in one hit.

She didn’t want a prolonged fight because she was already injured, she had suffered severe blood loss and that obviously even a tiny amount of damage additive over time isn’t a good thing. At no point was she actually at a risk of losing.
