Let's recap what we know so far.
Both Robinson Cano and Curtis Granderson will see their contracts expire before then—and both players are in line for fairly substantial raises.
Unless Swisher—who told ESPN New York's Wallace Matthews that he would like to stay in New York—is willing to take less than he'd get on the open market, the chances of him doing so are slim.
There are a number of expected veteran free agents who could fill the role, perhaps on a shorter and/or less expensive deal, including Andre Ethier, Ichiro and Torii Hunter.
Hunter, who turns 37 in July, still has a skill set that is very similar to Swisher: the ability to get on base and the ability to hit for power. Hunter beats Swisher out in defense and speed, but Swisher's influence on a clubhouse cannot be overlooked—though, by no means am I saying that Hunter is a bad guy to have in your clubhouse.
In comments to Bill Plunkett of The Orange County Register, Hunter is being realistic about his chances to stay in Los Angeles:
It'd be nice (to get an extension offer) but if not, I understand. There's no rush. They have other guys like (Erick) Aybar they need to lock up. Plus they've got (Mike) Trout lying in the weeds...I want to be back (with the Angels). In my mind, I tell myself I want to be back. But I can tell myself that. It's up to them.
Hunter, who is in the final year of a contract that pays him $18 million this year, will have to take a significant cut in salary regardless of whether he stays in Los Angeles or goes elsewhere.
Should he hit the open market, Hunter would be an excellent short-term replacement for Swisher, who much to the chagrin of Yankees fans, is likely nearing the end of his run in the Bronx.
