James Darnell could need another surgery on his left shoulder after injuring it at Triple-A Tucson on May 14. Darnell was hurt following a swing and was in San Diego last week to consult with team doctors. The 26-year-old has already had two operations on the shoulder -- one in 2011 and again in 2012 -- so this is obviously not a good development. Even if a decision is made against surgery, he'll be sidelined for a while.
