Stripling was optioned to Triple-A Oklahoma City on Friday.
During his start Tuesday against the Phillies, Stripling allowed three runs over five innings. While this wasn't his best outing, he's been a solid pitcher since the All-Star break, posting a 3.16 ERA and 1.05 WHIP over that time. However, the club needed to make room on the roster as Adam Liberatore and Bud Norris return from the DL. Stripling will head to Triple-A Oklahoma City, where he owns a 3.66 ERA and 1.32 WHIP.
