Within a few days, Carl Crawford will have an appointment with noted orthopedist Dr. James Andrews for an examination of what one baseball source characterized yesterday as "lingering soreness" in his left elbow.

"It's a fact-finding mission," Red Sox manager Bobby Valentine said yesterday.

Crawford opened the season on the disabled list after undergoing surgery in January on his left wrist. And while his wrist has healed, the left fielder started experiencing soreness in his elbow two weeks ago. He returned to Boston for an MRI exam, at which time he said the injury was diagnosed as a strain.

Last week, Crawford began serving as a designated hitter in extended spring training games in Fort Myers, but he hadn't been cleared to resume throwing. He was scheduled for a follow-up exam Tuesday in Boston, and the decision was made to send him to see Andrews in Birmingham, Ala., to "double check" that the injury isn't more serious, the source said.

"The elbow has improved, but there's still some soreness," general manager Ben Cherington said via text message yesterday. "So he's going to get a second opinion."
