Herrera (shoulder) will be sent to the Reds' minor league camp, C. Trent Rosecrans of the Cincinnati Enquirer reports.
The move signals that the second baseman is still unable to throw and will continue to be limited to a DH role moving forward. Pitchers begin seeing at-bats this coming weekend, so he would likely see more playing opportunities at a lower level. Despite the early setback, look for Herrera to be in the running for major league action at some point later this season.
