ARLINGTON -- Matt Bush is in danger of joining the Rangers' sad history of effective relievers who went south after trying to transform into starters.
The Rangers on Wednesday used Bush's final option to send him to Triple-A Round Rock. Manager Jeff Banister said the club wants Bush to throw more strikes. Bush's strikes rate had declined from 66.9 percent in his first two seasons to 56.6 this year.
"Any time a guy goes down, he has a chance to sharpen his skill set," Banister said.
This all started in the offseason, when the Rangers decided to grant Bush's request to try for a spot in the rotation.
