The likelihood of this move was reported earlier on STLtoday.com, and the original report can be found below.

The Cardinals maintained an opening on the 40-man roster by granting Chad Huffman his release so that he could become a free agent. The Cardinals had passed the outfielder through waivers in recent days before removing him from the 40-man roster.

From our earlier report:

The Cardinals are in the process of making a series of roster moves that will bring Harrison Bader to the majors and could install him as one of the outfielders for a stretch.

The exact nature of the move will be announced Tuesday afternoon, a team official confirmed to the Post-Dispatch.

Bader, 23, has been one of the leading forces for Class AAA Memphis this season with 19 homers and a .517 slugging percentage. He will have to be added to the 40-man roster before joining the active roster. The Cardinals have an open spot on the 40-man.

Earlier this month, the Cardinals considered Bader for a promotion but determined that he would not be a fit for a short-term call. If there was an extended run of playing time available then they would have given Bader a longer look.
