Darnell signed a minor-league contract with the Dodgers on Thursday, Eric Stephen of SB Nation reports.
Darnell was pitching in independent ball prior to this deal, although he does hold some major-league experience thanks to his 2014 stint with the Twins. However, he only managed to post a 7.13 ERA in that cup of coffee with Minnesota, so he'll likely spend most of his time with his new organization as an organizational depth piece.
