by Jeff Lippman | CBSSports.com
(4/21/2013) Houston recalled left-handed pitcher Brett Oberholtzer from Triple-A Oklahoma City Sunday, MLB.com reports. In the corresponding roster move the Astros sent pitcher Dallas Keuchel back to Triple-A.
Oberholtzer, who will pitch in relief like Keuchel did during his time in Houston, has made three starts for Oklahoma City. He's gone 0-2 with a 9.49 ERA.
Keuchel appeared in four games for Houston and had a 3.38 ERA over 10 2/3 innings.
