Still bothered by soreness in his left elbow, Carl Crawford plans to get a second opinion to determine if the injury is more sinister than a strain, according to Red Sox manager Bobby Valentine. "Until a guy is 100 percent, you always have concern," Valentine said yesterday. The Red Sox didn't provide additional information on the condition of Crawford's elbow or when and where the left fielder will see another doctor. In January, Crawford had surgery to clean up cartilage in his left wrist. The wrist has been progressing well, but two weeks ago, he experienced soreness in his left elbow, diagnosed as a strain. He has played in several extended spring training games in Fort Myers, serving only as a designated hitter, but hasn't been cleared to resume throwing. Crawford spent yesterday in Boston, having his elbow re-examined. Valentine said he was en route back to Fort Myers last night.
