Martinez revealed last week that he began experiencing more shoulder discomfort during his Minor League rehab assignment. He made just two appearances for Atlanta this year before being placed on the disabled list in early April with what was termed a right shoulder strain.
Martinez compiled a 3.86 ERA in the 120 appearances he has made since joining the Braves' organization in 2010. The 31-year-old right-hander has primarily served as a long reliever.
