Angels' Hansel Robles: Working as opener Sunday

Robles will work as the opener Sunday against the Mariners, Mike DiGiovanna of the Los Angeles Times reports.

Jaime Barria was expected to make this start, but he will instead come in later as the primary pitcher. Robles will face Mitch Haniger, Domingo Santana and Edwin Encarnacion to start off the game. This will be his first career start.
