Orioles right-hander Chris Tillman has been scratched from his scheduled start Sunday because of abdominal soreness that he first dealt with last week. Miguel Gonzalez, who was expected to follow Tillman, will instead start Sunday’s game against the Pittsburgh Pirates at Ed Smith Stadium, manager Buck Showalter said. Showalter said giving Tillman a few extra days of rest was a precautionary move after discussing the issue with team athletic trainer Richie Bancells. There’s no set timetable on his next outing.
