Adrian Del Castilllo went 0-for-4 with two strikeouts in the loss to the Giants on Wednesday.
Del Castillo’s glove always figured to hold him back, but he’s been a disaster at the plate this year, too, hitting just 182/.242/.291 with a 29 percent strikeout rate. The Diamondbacks might have room to keep him as a part-time DH after James McCann comes off the IL, but he’s just not giving them any reason to.
