EDGE Analysis

The 25-year-old exited Saturday's loss to Milwaukee with right groin tightness, and the injury has now been diagnosed as a strain. O'Neill will be eligible to be activated April 21, and he appears to be tracking toward a minimum IL stint, as manager Mike Shildt said the outfielder's imaging was "favorable," per Katie Woo of The Athletic. Lane Thomas was promoted to bolster the Cardinals' outfield depth.
