I'm not sure why the salary matters. The Twins don't carry payroll savings over year to year, so it wouldn't affect next year's budget (unless they account the $1m buyout into next year's payroll). If this year's payroll is maxed out, then ok, I guess it can't be done, but if there is still room, then they might as well use it. It's really moot anyway, since he didn't even make it to the Twins in the waiver priority, but philosophically, I'm not sure why the salary should matter.
