Impact King has played well in Triple-A this season, posting a 1.87 ERA, 1.14 WHIP and 41:14 K:BB over 33.2 innings while recording three saves and one win, and he'll provide the Astros with a southpaw option out of the bullpen. To make room for King, Houston designated right-hander Alex Speas for assignment.
