Vaughn (hand) isn't starting Wednesday against the Cubs, Vinnie Duber of AllCHGO.com reports.
Vaughn was hit by a pitch on his right hand in Friday's loss to the Angels and will be out of the lineup for a fifth straight game. Whether the 24-year-old will be available off the bench remains to be seen, but AJ Pollock will shift to left field while Adam Engel starts in right.
