Following Tuesday night's 4-2 loss to the White Sox at Tropicana Field, the Rays told reporters they were designating Martinez for assignment to make room on the roster for right-hander Jacob Faria, who is scheduled to start Wednesday night's game..
According to the Rays, that plan changed when they discovered Miller -- the team's starting second baseman -- had a right groin strain. So Miller will be on the DL, while Martinez will remain with the team for now.
