Gabbard to start Saturday for Texas

Left-hander replaces Mathis, who will move to bullpen

KANSAS CITY -- Young arms are becoming the new thing for Texas' rotation.

Manager Ron Washington said Kason Gabbard will start on Saturday, replacing Doug Mathis, who will move to the bullpen.

Gabbard started this season with the Rangers but was sent to Triple-A Oklahoma after going 1-2 with a 4.75 ERA in nine starts. He is the second young pitcher to join the rotation in the last week. Eric Hurley replaced Sidney Ponson and started on Thursday.

Mathis was 2-1 with a 7.52 ERA. The Rangers will have to make a roster change on Saturday to make room for Gabbard.

Texas also made a roster move on Thursday. Hurley was officially added to the team, and Kameron Loe was sent down to Triple-A Oklahoma. Loe was 1-0 with a 2.16 ERA in four appearances. He hadn't pitched since June 6.
