Agent Casey Close sued Fox Sports radio host Doug Gottlieb for libel Thursday, alleging that Gottlieb “falsely and recklessly” defamed Close and Excel Sports Management in a tweet that claimed they had not presented a contract offer to star first baseman Freddie Freeman during free agency. The lawsuit details Close’s negotiations with the Atlanta Braves, the team with which Freeman had spent his career before signing a six-year, $162 million free agent contract with the Los Angeles Dodgers in March. On June 29, Gottlieb tweeted: “Casey Close never told Freddie Freeman about the Braves final offer, that is why Freeman fired him” — an allegation the complaint says is false and has prompted death threats toward Close and tens of millions of dollars in damages to Close and Excel.
