In a two-page, 500-word report released Monday, Yankees GM Brian Cashman compared the destructive force of Alex Rodriguez's greed to the plight of Kino, the impoverished Mexican diver from John Steinbeck's 1947 novella, The Pearl. 'Just as when Kino discovered the 'Pearl of the World' and allowed his love of profit to supplant his love of family, so has A-Rod's desire for wealth perverted his immense talent. Once so pure and innocent, his natural ability has been transformed into nothing more than an agent for financial gain,' Cashman wrote, noting that A-Rod's dilemma exposes the fallacy of the American Dream and also that a baseball is like a giant pearl. 'If A-Rod gives in to the temptation of riches beyond his wildest dreams, he could suffer the same fate as Kinolowball offers from equally greedy owners, contempt from those who once loved him, and the death of his young son Coyotito.' Rodriguez called Cashman's comments untrue, confusing in parts, and repetitive, and gave him a D+.
