Witt (back) is not in the lineup for Saturday's game versus Minnesota, Anne Rogers of MLB.com reports.
Witt exited Friday's game with lower-back spasms and needs at least another day of rest. He underwent an MRI on Saturday, and the team is still awaiting the results, Rogers added. With Witt on the bench, Maikel Garcia slides over to shortstop and bats second with Nick Loftin entering the lineup at third base, batting seventh.
