Please explain. From what I remember, Hidan's scythe can be used mid-range, meaning he can get blood samples from a distance, even then, he has far more taijutsu skill than Sakura. In fact, his taijutsu score equals the likes of Kakashi, Lee, Neji, and Asuma. Hidan's tanked powerful attacks, and his body is not hindered by injuries. Nearly all wounds against Sakura are useless, which is why she's a threat to most, but head wounds cannot be healed, so all Hidan has to do is stab himself in the head when conditions are set and then Sakura dies.
In no intel, Sakura would surprise him and win, but in an intel situation, Hidan would win.
