Carpenter (back) will make his Grapefruit League debut in the field Wednesday against the Astros, Joe Trezza of MLB.com. He'll play first base and bat third.

EDGE Analysis

Carpenter checked out fine while serving as the Cardinals' designated hitter in Tuesday's exhibition against the Marlins, drawing walks in both of his plate appearances on the day. The veteran's return to the infield suggests the Cardinals aren't too concerned about his health heading into Opening Day, but Carpenter will still need to pick up several at-bats over the next week to ensure he's ready to handle a full-time role when the season begins. Expect Carpenter to also take reps at the hot corner in his subsequent appearances as the Cardinals look to open up room in the lineup at first base for Jose Martinez.
