Jung is batting seventh and starting at third base Tuesday against the Cardinals.
The Rangers are facing righty Lance Lynn, and perhaps Jung will bat higher in the order against lefties if he shows he's knocked all the rust off. Jung, who last played in the majors April 1 before needing surgery on a broken right wrist, slashed .296/.345/.333 with one double, nine strikeouts and zero walks in 27 at-bats during his rehab assignment. He was also hit by two pitches. Josh Smith, who played well in Jung's absence, is leading off as the designated hitter.
