Battle starts off...ends in a flash.
All depends if Sasuke can activate his susanoo in a flash,if not Minato solo's/marks,if so then battle drags on and Minato outlasts him or just uses space time barrier to manipulate his attacks against him..eg Susanoo arrow/amersterasu etc
Sasuke will be clueless on what Minato is doing with his Kunai...then in a instant the battle is over or like above^
Minato doms
