Randolph accepts assignment to RR:Left-hander Stephen Randolph, who spent two days with the Astros last week, cleared outright waivers and accepted an assignment for Triple-A Round Rock.
Randolph was called up to replace Rick White last Thursday in Pittsburgh, but the lefty was designated for assignment after Friday's game when the Astros needed a spot on the 25-man roster for Pence.
Astros general manager Tim Purpura was pleased that Randolph, who allowed one run over two appearances, accepted the assignment.
"When we visited with him we told him it wasn't a case where we planned to bring him up, but we had every confidence in bringing him up," he said. "When we went [from] 12 [pitchers] to 11, he obviously became the odd man out.
"He's making progress. I feel like he pitched good here except for the home run. His breaking ball was real sharp. One thing we pointed out to him in his career is he walked a lot of guys. He really cut down on them."
