The Injury
Adrian Del Castillo, the 26-year-old Diamondbacks catcher, suffered a left ring finger dislocation during the game against the San Diego Padres on Sunday, April 26, in Mexico City. The injury occurred when he received a Ryne Nelson fastball awkwardly on a foul tip while starting behind home plate. He was immediately checked out by a trainer and did not spend much time being evaluated before walking off the field.
Context and Roster Impact
Del Castillo's injury compounded the Diamondbacks' injury problems. The team was already without starting catcher Gabriel Moreno, who is dealing with an oblique strain and not expected back until early May. Del Castillo and veteran James McCann had been sharing catching duties in Moreno's absence. With Del Castillo's exit, McCann took over the catching role, while veteran Aramis Garcia became the backup catcher.
Severity and Next Steps
Del Castillo took the pitch off his gloved hand rather than his bare hand, which was a positive sign. However, he carried no official injury designation at the time of reporting, and the team indicated he may have to undergo imaging to determine the severity. The Diamondbacks had an off day on Monday, April 27, which provided time for evaluation. Hand injuries can be particularly tricky for catchers, though there was optimism that Del Castillo may not have to miss significant time.
Recent Performance
Del Castillo had seen his bat cool off recently after a hot start to the season, serving as the regular left-handed DH as well as a platoon catcher. However, he showed improvement on the defensive side this season, rated around league average in defensive metrics, representing a positive step for the organization.
