Rotation shuffle in Oklahoma City

Rotation shuffle in Oklahoma City

HOUSTON -- With right-hander Jordan Lyles shuffling between Triple-A and the Majors -- he pitched for the Astros on Sunday and will likely return to make a start at Colorado next Monday -- and the rights to Henry Sosa being sent to Korea, the Astros are trying to fill a rotation spot in Oklahoma City.

Wes Musick, a left-hander the Astros required in the Matt Lindstrom trade with Colorado following the 2010 season, was called up from Double-A Corpus Christi to make a spot start on Monday for the RedHawks against Colorado Springs.

He began the year in Class A Lancaster and went 3-1 with a 2.51 ERA in five starts, including a complete-game loss at Lake Elsinore, before pitching in three games at Corpus Christi. The Astros on Monday signed Armando Galarraga, who's expected to join the rotation soon.
