In a May 19 game against the Blue Jays, Castillo hit his first home run at Camden Yards as a member of the Orioles. He would later hit a two-run home run in the tenth inning of the same game to walk it off for the Orioles. This streak ended the next night, however: he hit a go-ahead, game-winning three-run home run in the seventh inning to lead to Orioles to a 7–5 victory. It gave Castillo an RBI in six consecutive games and extended his overall hit streak to nine games.

Castillo was again placed on the 10-day DL on May 31 after taking a deflected pitch in the groin area. He was activated off the DL on June 10 and was immediately slotted back into the Orioles' starting lineup. On June 14, Castillo hit his first career grand slam off former Oriole Miguel González, giving the Orioles an 8–5 lead over the White Sox and helping the Orioles end a six-game skid.
