Harvey suffered a groin strain during a minor league game Tuesday, Brittany Ghiroli of MLB.com reports.
The 21-year-old Harvey will visit a doctor Wednesday to determine the extent of the injury. A first-round pick in 2013, he missed all of last year due to elbow troubles, but Harvey came into camp at 100 percent. He was not sharp in his brief time with the big club this spring, allowing six runs on six hits and four walks over 2.2 innings before being reassigned.
