Matusz (back) will have a "real challenge" to make the Opening Day roster, Orioles manager Buck Martinez told Roch Kubatko of MASN on Thursday.

EDGE Analysis

Matusz has been dealing with a back injury all spring after undergoing shoulder surgery this offseason. Expect him to open the season on the disabled list at this point. The Orioles may look at add a lefty like T.J. MacFarland to the roster in Matusz's absence.
