The Giants declined to tender Sanchez (ankle) a contract for 2016, Andrew Baggarly of the Bay Area News Group reports.
Sanchez was the odd man out of the catching mix with Andrew Susac (wrist) and Trevor Brown emerging as viable options behind Buster Posey. Ankle and hamstring injuries cut Sanchez's 2015 season short, but he was able to avoid another concussion scare after battling head injuries throughout the second half of 2014.
