Triple-A Jacksonville placed Alderman on the 7-day injured list Tuesday due to a left wrist injury, Michael Germanese of Roundtable.io reports.
The Marlins haven't provided word on the severity of Alderman's injury, but he may have suffered a fractured wrist after he was involved in a collision at first base with a baserunner last Sunday, per FishOnFirst.com. Prior to leaving that game, Alderman smacked two home runs, bringing his slash line up to .303/.376/.526 over 170 plate appearances on the season. The 23-year-old appeared to be building a case for a call-up to the big leagues, but the wrist issue will take a promotion off the table for the foreseeable future.
