OAKLAND -- The Rangers are well aware of what left-hander Derek Holland has done at Triple-A Oklahoma City. There are no plans right now to call him to the Major Leagues either, but he is becoming a strong option if the Rangers have a need in their starting rotation.
Holland went to 4-1 with a 0.93 ERA in Oklahoma City's 10-5 victory over Omaha on Tuesday night.
"He's throwing great," general manager Jon Daniels said. "He's really commanding his fastball, his slider has improved and his changeup has been good. He's definitely opened some eyes. He's an option if we have a need."
The Rangers don't have a need right now. Rich Harden was terrific with seven scoreless innings on Monday night and is 2-1 with a 3.52 ERA. Any suggestions he was moving to the bullpen as a long reliever to work out his problems were way off-base.
Scott Feldman is 1-3 with a 5.45 ERA in six starts, but he won 17 games last year and just agreed to a two-year contract extension. The Rangers feel he has earned the right to get as much time as possible to work out his problems.
Matt Harrison is 1-1 with a 4.97 ERA and he could be considered the most vulnerable pitcher in the rotation. He pitches Thursday against the Royals, but also beat Mariners ace Felix Hernandez in his last start.
Daniels did make it clear that Holland is only a candidate for the rotation and not likely to be called up to pitch in relief.
"We want to keep him stretched out and starting," Daniels said.
