The Yankees transferred Stanton (calf) to the 60-day injured list Tuesday.
The veteran slugger was working his way back from a right calf strain last week when he suffered a moderate strain of his left calf, further delaying his return from the injured list. This transaction doesn't mean much given that Stanton has already been sidelined well beyond the 60-day minimum. After suffering the setback, manager Aaron Boone indicated it will be "challenging" for the 36-year-old to make it back before the end of the regular season, per Jorge Castillo of ESPN.com.
