A friend who called 911 when Jennifer Capriati overdosed on prescription medication was concerned for her safety because she was going through "personal things," according to a portion of the call obtained by The Associated Press on Wednesday. The caller's name was not released and he identified himself as a friend. He said he had just spoken with the former top-ranked tennis player and that she "couldn't form a sentence." "I tried calling her and when I was talking to her, she couldn't even talk," said the caller, adding that he hoped she might be kidding. "But if she's not, I don't want to take a chance," he said. http://sports.espn.go.com/sports/tennis/news/story?id=5521361
