The Blue Jays re-signed Martin to a minor-league contract Thursday, Ari Alexander of 7 News Boston reports.
Martin elected free agency earlier this week after being removed from the Blue Jays' 40-man roster, but he's found his way back into the organization and has been invited to spring training as a non-roster invitee. The speedy Martin reached the majors for the first time this season, going hitless in three plate appearances.
