The Rangers optioned King to Triple-A Round Rock on Wednesday.
King had a rough go of it in the Cactus League with a 5.06 ERA, 1.78 WHIP and 12:4 K:BB over 10.2 innings of work. The southpaw will begin the season in the Pacific Coast League, but he likely will see time in the Texas bullpen as an up-and-down option for the club for the 2023 campaign.
