The Baltimore Orioles activated pitcher day disabled list and placed pitcher Jason Berken on day DL with a right shoulder strain Monday.

Britton was placed on the disabled list on August 5 with a left shoulder strain.

The 23-year-old rookie will start Monday's contest against the Minnesota Twins, and is 6-9 with a 4.66 ERA in 20 starts for Baltimore this season.

Berken has made 35 appearances out of the Orioles' bullpen this year and carries a 1-2 record with a 5.80 earned run average.

To replace Berken on the roster, infielder Ryan Adams was recalled from Triple-A Norfolk.
