Who won the match between John Cena and The Miz at WrestleMania 27?

First no one lost due to a double count-out. Then The Rock (who was the host of WrestleMania 27) came in and said they'll restart the match to get a winner. John Cena had control of the match, but then The Rock used Rock Bottom (one of his finishers) on Cena, and The Miz pinned him.
