ARLINGTON, Texas -- The Detroit Tigers have scratched left-hander Dontrelle Willis from Saturday night's start against the Texas Rangers because of an upset stomach.

Instead, left-hander Brad Thomas will make his sixth major league start.

Willis is 0-1 with a 4.24 ERA in three starts.

Thomas had a 7.04 ERA in four relief appearances this season.
