Del Castillo went 2-for-4 with a grand slam and a two-RBI single during Monday's 9-6 win over the Marlins.
Del Castillo's excellent rookie campaign got even better Monday, as he delivered his first career grand slam as part of a six-RBI day. The 24-year-old has homered in back-to-back games and is slashing .333/.405/.668 through 37 plate appearances. Del Castillo has been working on the strong side of a platoon with Jose Herrera behind the dish, and with Gabriel Moreno (adductor) not close to returning, Del Castillo should continue to see plenty of catching work.
