Herrera will open the year with Low-A Peoria, Mike Rosenbaum of MLB.com reports.
EDGE Analysis
Herrera is one of the better catching prospects in the lower levels of the minors, and he will be given an aggressive assignment to Low-A as an 18-year-old. He hit .348/.423/.500 with a 15.4 percent strikeout rate in 28 games in the Gulf Coast League last year, but it would not be surprising if he struggled, at least initially, against Low-A pitching.
