Cardinals Promote Jordan Walker as Matt Carpenter Hits Injured List

Walker returns to the majors after a strong performance in Triple-A, aiming to boost the lineup against left-handed pitchers.

Jordan Walker has been recalled from Triple-A Memphis following Matt Carpenter's lower back injury.
Walker, 22, showed significant improvement in his swing, hitting .349 with a .404 on-base percentage this month.
The Cardinals hope Walker's right-handed bat will help their struggles against left-handed pitchers.
Walker initially struggled in the majors this season, hitting just .155 before being sent down.
Matt Carpenter, 38, has been placed on the 10-day injured list retroactive to August 9.
