SEATTLE-The Orioles activated outfielder Colton Cowser from the 60-day injured list on Monday. Cowser, who fractured his left thumb diving into first base in the season’s fourth game on March 30th, is 2-for-16 (.125) with a home run and RBI.

To make room for Cowser on the active roster, the Orioles designated utility player Cooper Hummel for assignment. He was hitless in one at-bat.
