Mat Latos has been scratched from a rehab start with Triple-A Louisville on Tuesday, but the Cincinnati Reds have not given a reason.

David Holmberg will start in the place of Latos.

Latos had offseason surgery on his right elbow and his left meniscus. He has made one rehab start with Double-A Pensacola this season, allowing five runs on seven hits and one home run in four innings, and he did not appear in any Spring Training games.
