Carpenter will serve as the Cardinals' designated hitter and No. 8 batter in Monday's game against the Padres.

Carpenter has been the main beneficiary thus far of the Cardinals' decision to demote the struggling Nolan Gorman to Triple-A Memphis last Wednesday. With Gorman out of the mix, Brendan Donovan and Alec Burleson have been seeing most of their starts lately at second base and in left field, respectively, leaving the DH spot available for Carpenter. Though he'll be getting his fifth start in the Cardinals' last six matchups with right-handed pitchers, Carpenter has yet to do much with the opportunity. He's gone 0-for-11 with three walks over his last five contests.
