EDGE Analysis

McWilliams confirms that top prospect Triston Casas will join the club and adds that it will be Dalbec who loses his roster spot. Dalbec was once a top prospect himself, but he has struggled to a .211/.282/.362 line this year. He will now attempt to reset himself at Triple-A before potentially rejoining the club late in the season.
