Andrew Friedman acquired Josh Fields in an under the radar move during the 2016 season. Friedman traded prospect Yordan Alvarez to the Astros to get Fields to the Dodgers. Typical Friedman move as he got him when the asking price for Fields was at its lowest.
During the 2016 season with the Astros, Fields was struggling. He had a 6.89 ERA in 15 appearances with Houston. Also, his three seasons prior had not been anything special. So when Friedman acquired him it was just another one of those low risk, high reward moves that he loves to make.
