BALTIMORE (AP) — Top Orioles pitching prospect Grayson Rodriguez has a strained lat muscle, Baltimore general manager Mike Elias said Thursday.

It’s not clear how long the right-hander will be out. Elias said Rodriguez came to Baltimore for an MRI, which confirmed the strain.

Rodriguez, the top pitching prospect in baseball according to MLB Pipeline, seemed on the verge of reaching the majors soon, but he left Wednesday’s start for Triple-A Norfolk with discomfort in the lat area.

The 22-year-old Rodriguez is 5-1 with a 2.09 ERA in 11 starts for Norfolk this season. He’s a big part of Baltimore’s rebuild, along with catcher Adley Rutschman, who was recently promoted to the majors.
