With regular shortstop Aledmys Diaz currently on the disabled list, the Blue Jays have been using a number of players at the position.
Martin has appeared in one game at shortstop this season, logging one inning of work on May 15 against the New York Mets. The 35-year-old natural backstop has also seen time at third base this year.
Martin is hitting .157/287/.322 through 34 games in 2018.
The Blue Jays also optioned Dalton Pompey to triple-A Buffalo to make room on the roster for left-handed pitcher Jaime Garcia, who drew the start Saturday.
