Zack Greinke can block trades to 15 teams and Jon Paul Morosi of FOX Sports reports that the Yankees, Red Sox and Nationals are among them. The Tigers, Angels and Rangers, however, could acquire the right-hander without his permission.
The Yankees reportedly have limited interest in Greinke, but the Nationals have shown interest in acquiring Greinke or Matt Garza. Though the Tigers and Angels haven't been linked to Greinke much this offseason, the Rangers are often mentioned as a possible destination for the 2009 AL Cy Young Award winner. They prefer him to Fausto Carmona, according to Morosi (on Twitter). Greinke has two years and $27MM remaining on his contract.
