Mariners acquired INF Daniel Castro from the Dodgers for INF/OF Kristopher Negron; assigned him to Triple-A Tacoma.
Castro, 26, has spent the entire 2019 season in the Dodgers’ minor league system and was batting .241/.304/.295 in 185 plate appearances at Triple-A. But he is about seven years younger than the 33-year-old Negron.
