Is There a Market for Jeremy Affeldt?

Ken Rosenthal is reporting that the Giants are shopping Ramon Ramirez and Jeremy Affeldt to try to make some room in the payroll.

It is a little peculiar that the Giants are looking at trading Affeldt right after picking up his option, especially considering his relatively high salary at $5 million for this season but I guess the front office has had a change of heart or think the market for relievers has changed enough that flipping him might make sense.
