From June to December 2012, Colletti, with the backing of a new, aggressive ownership team led by Dodgers' president Stan Kasten, owners Mark Walter, Earvin "Magic" Johnson, Peter Guber, and Guggenheim Baseball Management, spent more than $600 million to bring a parade of all-star players and prospects to Los Angeles. The wholesale makeover began in late June when the Dodgers spent $42 million to sign 21-year-old Cuban prospect Yasiel Puig to a six-year deal. On July 25, Colletti brought in former National League batting champion Hanley Ramírez as the key to a four-player trade with the Miami Marlins.
