Nationals make roster moves with Robles on IL and Hill called up.
The Washington Nationals have placed center fielder Victor Robles on the 10-day injured list for the second time this season due to back spasms, a day after a dugout tiff with pitcher MacKenzie Gore. Outfielder Derek Hill was selected from Triple-A Rochester to replace Robles on the roster. The Nationals also placed right-handed reliever Carl Edwards Jr. on the 15-day IL with right shoulder inflammation and recalled lefty Joe La Sorsa.
