Herrera will be a part of the Cardinals' taxi squad this season, Jesse Sanchez of MLB.com reports.
Herrera was a part of major-league camp during spring training this year, where he went 2-for-9 over five games before play was suspended. While the 20-year-old is likely viewed as the Cardinals' catcher of the future within the organization, it's unlikely that he'll see significant playing time in the majors this season given his lack of experience above High-A.
