Russell Martin calls it his "mental hard drive." Stored on it is a lot of footage of the Yankees catcher's old Dodger teammate, Hiroki Kuroda, and how the righty's split-finger fastball plummets and how the short break on Kuroda's slider elicits weak contact.

Also tucked in there is a memorable moment from Kuroda's first spring training in the majors, 2008, when the quiet newcomer donned full Elvis Presley regalia, including sideburns and a wig, for some rookie hazing that had an "American Idol" theme.
