Del Castillo has gone 1-for-3 at the plate while making no starts and being used off the bench in just two of Arizona's last eight games.
After joining the Diamondbacks on April 3 following a brief stint on the injured list to begin the season, Del Castillo had seen fairly steady playing time against right-handed pitching between designated hitter and catcher over the ensuing two months. However, his opportunities to catch began to dry up once Gabriel Moreno coming off the IL on May 1, and Del Castillo's playing time at DH has now dwindled over the past week with Pavin Smith returning from the shelf. With Arizona signing Max Kepler to a one-year deal Sunday, Del Castillo will likely face an even more difficult path to receiving at-bats once Kepler is eligible to join the Diamondbacks on June 25 upon completing his 80-game suspension.
