The game began in bright fashion, with Development talent Brandon Pierrick unnerving the visitors with a smart attempt in the Rams' penalty area. But former Palace man Chris Martin netted shortly after the half hour mark and this ultimately proved to be the winning goal by full-time.
The Eagles lost Max Meyer and Jairo Riedewald to injury and Luka Milivojevic received a red card after Michael Oliver's consultation with VAR and the pitchside screen.
