Robberse (elbow) was activated from Triple-A Memphis' 7-day injured list Wednesday.
Robberse made three rehab starts at Single-A Palm Beach, allowing two runs (one earned) on nine hits and a walk while striking out four over six innings. The Cardinals will likely stay cautious with the right-hander to close out the campaign, but he should be able to get at least two or three more appearances with Memphis before the end of the season.
