The Astros optioned King to Triple-A Sugar Land on Thursday, Ari Alexander of KPRC 2 Houston reports.

EDGE Analysis

This looks like merely a numbers game and King having minor-league options available, as his 2.05 ERA and 27:9 K:BB over 22 innings doesn't point to a guy deserving of a demotion. King should be back in the Houston bullpen soon enough.
