The Philadelphia Phillies entered spring training with expectations that some of their top prospects would make their major league debuts this season. Andrew Painter and Justin Crawford are both on track to make the Phillies' Opening Day roster. Aidan Miller, who wasn't going to make their roster at the beginning of the regular season, but still had an opportunity to impress, has instead suffered a setback this spring due to a back injury.
Miller, the Phillies' top-ranked prospect, according to MLB Pipeline, demonstrated his potential during the final two months of the regular season last year.
