Mejia (biceps) will shift his minor-league rehab assignment to Double-A Chattanooga.
Mejia allowed just one run in two prior rehab starts (eight innings) for Triple-A Rochester. However, with the minor-league season ending, he'll join the playoff-bound Lookouts as he looks to make one final rehab appearance before rejoining the Twins. Mejia has been sidelined since Aug. 9 with a biceps strain; his return date will hopefully come into focus after his next rehab outing.
