The Orioles designated Soriano for assignment Monday.
The transaction frees a spot on the 40-man roster for waiver claim Jhonkensy Noel. Soriano himself was a waiver claim of the Orioles earlier this offseason, and he'll go through the waivers process again. The 26-year-old holds a 5.95 ERA and 117:55 K:BB in 118 innings across parts of three seasons in the big leagues.
