The Orioles recalled Soto from Triple-A Norfolk on Thursday.
Soto will come up from the minors and will serve as infield depth with Jordan Westburg (hand) heading to the injured list in a corresponding move. The 24-year-old has played in just one major-league game this season with the Reds, but he owns a .279/.378/.375 slash line through 329 plate appearances at the Triple-A level between three different organizations.
