I mailed 2 cards to Casey Janssen, c/o The Toronto Blue Jays on 09/01/2009 and received 2/2 back on 04/07/2010. 210 days. I honestly had thought I would not get these back. Casey had some injury troubles over the last 2 seasons, but hopefully, this year he can stay healthy and help the Blue Jays. They will need all the help they can get.
