The Orioles acquired Soto and outfielder Austin Slater from the Reds on Tuesday in exchange for cash, Mark Sheldon of MLB.com reports.
Soto was designated for assignment earlier in the day by the Reds, but the Orioles -- who claimed Soto on April 11 only to DFA him five days later -- swooped in and got him at the deadline. Given that Soto has minor-league options remaining, he will likely stick with Triple-A Norfolk for the time being.
