Cano and Granderson can test free agency after the 2013 season, carrying expensive club options for next year -- Cano's is for $15 million, while Granderson carries a $13 million club option.
The Yankees seem likely to pick both options, but Cashman wouldn't say if the club's financial parameters -- hoping to reduce payroll below $189 million in 2014 -- would allow them to keep both players on the roster beyond that.
"You just can't predict it," Cashman said. "Obviously we love what Robinson Cano does for us, we love what Curtis Granderson does for us. We gravitate to players that we feel can be champions and take us to the next level. I think we have a collection of those guys and we have some young guys coming."
Cashman said that the free-agent market often dictates such events, noting that the Cardinals made an effort to retain Albert Pujols but still watched him go to the Angels. Cashman also said that the Yankees may have a tough fight to retain catcher Russell Martin after this season.
"He's a year from free agency and we'd like to retain him," Cashman said. "Can we? I don't know. It doesn't change who he is as a player, but he's going to have opportunities, we're going to pursue retaining him in the future, but there's no guarantee we'll have him."
