Mark Kotsay evaluates Athletics rotation options following Severino's injury

Athletics manager Mark Kotsay is assessing his pitching rotation after Luis Severino sustained a strained right shoulder, sidelining him for at least four to six weeks. The team promoted right-handers Kade Morris and Mason Barnett from Triple-A Las Vegas ahead of a 2-1 victory against the Chicago Cubs. Morris, a top prospect, is poised for his major league debut, while Barnett has recorded two scoreless innings earlier this season. Meanwhile, the Athletics are also without Aaron Civale due to shoulder tendinitis. Gage Jump, who recently earned his first career win, is filling a rotation gap. All-Star shortstop Jacob Wilson is nearing a return from injury and may start a minor league rehab assignment soon.
