Flynn was informed Friday that he won't be on the Rangers' 60-man roster, Levi Weaver of The Athletic reports.
Flynn made 11 appearances for the Royals in 2019 prior to be designated for assignment, and he posted a 5.22 ERA and 22:17 K:BB prior to heading to Triple-A Omaha. He signed a minor-league deal with the Rangers during the offseason and was invited to major-league camp in the spring, but he won't be part of the active roster to begin the abbreviated 2020 campaign.
