Mayer is out of the lineup for Sunday's game against the Tigers.
Mayer will hit the bench for the second game in a row while the Tigers send another lefty (Framber Valdez) to the mound for the series finale, after two-time Cy Young Award winner Tarik Skubal took the hill for Detroit on Saturday. Isiah Kiner-Falefa will cover second base Sunday in Mayer's absence.
