Geoff Baker of the Seattle Times reports that the Astros will sign Roy Corcoran, who just became a free agent. The 29-year-old righty hit free agency after refusing an assignment to the Mariners' Triple A team. He allowed 25 hits in 19 innings with the Mariners and walked about three times as many batters (17) as he struck out (6).
The Mariners designated Corcoran for assignment late last month.
