A Los Angeles promoter said he is offering 39-year-old Jimmy Connors and 17-year-old Monica Seles $1 million to play a winner-takes-all "Battle of the Sexes" match in Las Vegas.
Promoter David Krieff of Destiny Productions said the rules would be amended to give Connors only one serve and allow Seles to play the doubles alleys as in bounds.
Said Ray Benton, Connors' agent: "There have been conversations but to date no substantive negotiations."
Stephanie Tolleson, who represents Seles, was unavailable for comment.
