Yu Darvish admitted Tuesday night that he's dealing with an undisclosed physical issue. Darvish has failed to go at least six innings in consecutive starts for the first time this season, but the Rangers are classifying his ailment as "normal wear and tear." Manager Ron Washington added that "everybody has issues that they're dealing with and (Darvish is) no different." Darvish will start the regular season finale on Sunday against the Angels.
