This is a rare baseball mail day. I stopped sending requests to MLB players because it became a waste of stamps. I was only receiving about 35% of my requests back and my hometown Jays seemed to stop signing through the mail.
On occasion an old request will come back. I sent this one out right after the OPC set came out in 2009. Not a bad success from a potential future ace.
