The American League’s reigning Rookie of the Year has been shut down with a high-grade lat strain following an MRI, Aaron Boone told reporters on Monday. The Yankees ‘ manager said that Gil won’t throw for at least six weeks as he continues to get exams and opinions from doctors.

Clarke Schmidt can relate. The righthander, off to a terrific start last season — 5-3 with a 2.52 ERA through 11 starts — suffered a lat strain during a May 26 outing in San Diego and missed more than three months. His next big-league start was Sept. 7.

Yankees right-hander Luis Gil will start the season on the injured list because of a high-grade lat strain in his pitching shoulder that will prevent him from throwing for at least six weeks.
