Minato wins in speed, Itachi in genjutsu. The Yellow Flash would have to avoid getting caught in Itachi's genjutsu in order to win, which isn't quite easy. Itachi would have to avoid getting marked, so he'd resort to mid-to-long range fighting, but even so, there's Minato's custom kunai to watch out for. If Minato gets at close range, a Rasengan would finish it, unless Itachi decides to resort to Susanoo. Amaterasu couldn't work on the Fourth Raikage, who's slower than Minato.
