The Astros have claimed right-handed pitcher Blake King off waivers from the Cardinals, according to a team press release. The 24-year-old was placed on the Astros 40-man roster and optioned to Double-A Corpus Christi.
King failed to impress in 2011 at the Triple-A level after spending the bulk of his time in Double-A Springfield. In 58 career Double-A appearances, the 6-foot-1 hurler has a 3.47 ERA with 11.1 K/9 and 7.1 BB/9.
