Rangers signed 1B/DH Lance Berkman to a one-year, $11 million contract. The deal also includes an option for 2014 that will vest if he reaches 550 plate appearances, which doesn't seem likely to happen given the condition of his knees. Berkman will serve as the Rangers' regular DH and is likely to produce as long as he stays on the field, but that's hardly a given. He was limited to just 32 games this past season due to injury.
