The Orioles claimed Soriano off waivers from the Marlins on Wednesday.
In 118 innings across parts of three seasons in the big leagues, Soriano has collected a 5.95 ERA and 117:55 K:BB. The 26-year-old reliever does not have minor-league options remaining, so he would have to go through the waivers process again if he doesn't make the Orioles' Opening Day roster.
