Kakashi could be another character to rescue Sakura. He is a very experienced ninja and has mentored Sakura in the past. He might use his Sharingan or some of his unique jutsu to outwit the clone Itachi and free Sakura. And he's always looking out for his students, so it would be in character for him to step in and help.
