After the post-trade deadline dust settled, the Washington Nationals needed to make a roster move to get back to an active-26. Mason Thompson was the newest face, added when Jon Lester was traded away. That meant, to get Josiah Gray to the active roster there would have to be a demotion. To the surprise of most, Tanner Rainey was the one demoted to Triple-A.
