The Yankees optioned Dominguez to Triple-A Scranton/Wilkes-Barre on Monday.
With Heliot Ramos coming over from the Giants, Dominguez is no longer with the big-league club. Dominguez was heavily featured in trade talks, but ultimately stayed with the Yankees after Monday's trade deadline. The 23-year-old has slashed .230/.271/.383 with six home runs and 14 RBI.
