Yanks' Stanton suffers setback, return in jeopardy

New York Yankees slugger Giancarlo Stanton has suffered a 'moderate grade' left calf strain while rehabbing from a separate right calf strain, manager Aaron Boone announced. The new injury puts Stanton's return this season in serious jeopardy. The setback is a significant blow for the Yankees, as Stanton was already sidelined before sustaining this additional injury to his other leg.
