The value of the backup catchers has been stated many, many times and does not need further explaining. We have seen how they contribute to the team both on the field and in the clubhouse. Right now the Chicago Cubs catcher-tandem for 2019 is Willson Contreras and Victor Caratini.
Caratini, while showing some improvement toward the end of last year, overall was underwhelming. It is possible he may never reach his potential with the Cubs being a prospect trying to develop as a backup in the majors, having already succeeded in Triple-A.
