No, he is not a member of the late Merle Haggard’s family. He is another one of those invisible Dodgers minor leaguers pitching above expectations. Justin Hagenman was selected by the Dodgers in the 23rd round of the 2018 First-Year Player Draft as a junior out of Penn State., 704th overall.
He was born in Voorhees, New Jersey and attended Bishop Eustace Preparatory School in Pennsauken,NJ.
At Bishop Eustace Hagenman was a teammate of left-hander Devin Smeltzer who had been drafted by the Dodgers in the 5th round of the 2016 June Draft. Smeltzer currently is in the Twins organization with the AAA Rochester Red Wings and having a good season.
