An outfield that is already missing Logan Morrison because of injury is now faced with another major concern: Chris Coghlan. Coghlan left Wednesday's game after going to manager Edwin Rodriguez and telling him that his (right) throwing shoulder was too sore to continue. "He was playing with pain and, after his last at-bat, it was too much," Rodriguez said. Nobody knows whether Coghlan will be able to play Friday for the Marlins' next game. "We'll have to wait and see," Rodriguez said. But for any player to admit to his manager that the pain is too great to continue is a troubling sign for the Marlins. The shoulder is the same one that caused Coghlan to miss the bulk of spring training. He said the soreness has continued off and on ever since. On Wednesday, the pain became "sharp," he said. "It was something I couldn't keep going on," Coghlan said. Coghlan and Morrison, who is on the disabled list with a strained left arch, are tied for the team lead in home runs with four.
