The Yankees are open to trade scenarios involving Curtis Granderson, according to ESPN's Buster Olney (Twitter link). Olney notes that moving Granderson's $15MM salary would give general manager Brian Cashman more flexibility this offseason.
Granderson will turn 32 next March and has seen his power numbers soar in the homer-friendly Yankee Stadium. Over the past two seasons he's batted .247/.342/.522 with a whopping 84 homers. Following a fourth-place finish in MVP voting in 2011 though, Granderson saw his walk rate decline and his strikeout rate rise substantially in 2012.
Several teams are looking for center field help, though the market has shrunk with the signings of B.J. Upton and Angel Pagan and the Nationals' acquisition of Denard Span. The Phillies and Mariners strike me as teams in need of outfield help that could take on Granderson's hefty salary, but that's just my speculation.
Cashman said in late October that he would keep an open mind in regards to trading Granderson, but stressed the difficulty of replacing a 40-homer bat in center field.
