News: Headley signed a four-year, $52-million deal with the Yankees on Monday, Jon Heyman of CBS Sports reports.
Impact: 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 (suspension) to a DH/backup third baseman role.

News: Headley is staying with the Yankees, giving New York insurance at third base in case Alex Rodriguez is unable to play the field regularly.
Impact: With Headley available to play third in A-Rod's place, the Yankees would be able to use Martin Prado at second. The 30-year-old Headley was acquired from San Diego in July. The 2012 NL Gold Glove winner at third, he hit .262 with six homers and 17 RBIs in 191 at-bats for the Yankees.
