The Dodgers designated Hernandez for assignment and outrighted him to Triple-A Oklahoma City on Friday.
With the addition of Kolten Wong to the active roster Friday, Hernandez will remain in OKC but lose his spot on the 40-man. The 25-year-old is slashing .252/.407/.363 across 339 plate appearances in Triple-A and will likely remain in the minors to conclude the season.
