Headley has signed a 4-year, $52-million deal with the Yankees, Jon Heyman of CBS Sports reports. While he probably won't put up a .371 on-base percentage with the Yankees again this season, Headley should still be valuable long-term for them thanks to his defense. The 30-year-old's offense will likely continue to diminish though; his batting average has gone down every year since 2011. This will likely displace the returning Alex Rodriguez to more of a DH/back-up third base situation.
