I got another RTS for the Brewers at ST today. I called the front office and spoke to the operations manager and explained that I had a RTS with a forwarding address for 3805 53rd Ave. She advised that is the minor league complex and when they break camp they have their mail forwarded to that address. That forward had expired. She called the operations person in ST had made him aware of it and said if you resend now it should be ok. I confirmed the address as:

Milwaukee Brewers
Maryvale Baseball Park
3600 N. 51st Avenue
Maryvale, AZ, 85031
