The Athletics announced on Friday that they have designated right-hander Taylor Thompson for assignment in order to clear a spot on the 40-man roster for Brad Mills, whose contract will be selected from Triple-A so that he can start tonight’s game.
The 28-year-old Thompson hasn’t pitched in the Majors this year and has just 5 1/3 big league innings total throughout his career, all of which came with the White Sox in 2014. He’s spent most of the season on the 60-day DL due to a shoulder strain, though he was recently activated and began pitching at Class-A Advanced before moving up to Triple-A.
