The team indicated that Jonah Tong could join the major league squad at a later date. Juan Soto and Mark Vientos returned to the active lineup following stints on the injured list. Elsewhere in the league, the Baltimore Orioles claimed Luis Robert Jr. off waivers. The National League Rookie of the Year race remains unsettled following an injury to JJ Wetherholt.
