This spring's competition for the fifth spot in the Orioles' starting rotation came a little bit closer to a conclusion Saturday when the team optioned left-hander Zach Britton to Triple-A Norfolk.

The team also optioned infielders Jonathan Schoop and Yamaico Navarro to Triple-A and reassigned right-hander Daniel McCutchen to minor league camp. Those moves trim the Orioles' spring roster to 40 players.

In five Grapefruit League outings this spring, the 25-year-old Britton had a 6.10 ERA, allowing 13 hits and seven runs in 10 1/3 innings with seven strikeouts and four walks. He also allowed three earned runs in three innings in an exhibition game against Spain's World Baseball Classic team.
