THE CASE FOR: Headley brings a professional approach and switch hitting. Yes, he was awful in April last year, but he hit a solid .265 with 14 HR and 49 RBI after May 1. Like Castro, Headley lets Girardi split up his lefties.
THE CASE AGAINST: While he's a smart, savvy baserunner, teams won't see Headley as a threat to run.
Yankees general manager Brian Cashman has said that manager Joe Girardi floated the idea of a change at the top of the lineup last season. That led to Girardi flipping Jacoby Ellsbury out of the leadoff spot and putting him second behind Brett Gardner.
