"His arm is a little sore," manager Tim Bogar said. "He has been getting treatment on his triceps. We're going to skip him and see how long it takes. There are no plans other than to let him get his triceps healthy."
Bonilla was one of two pitchers acquired from the Phillies two years ago for infielder Michael Young. The Rangers acquired him as a reliever but turned him into a starter this season while he was pitching at Triple-A Round Rock. He was 1-1 with a 3.60 ERA in six starts for the Express.
He made his big league debut on Sept. 4 and has made two relief appearances, but this will be his first start in the Majors.
"I'm very proud to get to start a game," Bonilla said.
