Major League Baseball's expected sponsorship deal with Pizza Hut (AA, Oct. 30) may now be not so imminent after all. Sports marketing executives familiar with the situation said talks between MLB and Pizza Hut have broken down and that the deal is off--for now. Executives said the breakdown came because Pizza Hut wants a little more of the marketing pantry than MLB is willing to give. The proposed deal was said to be on par with True Value's recent three-year, $40 million pact. Insiders said to look for Burger King Corp., suddenly very interested in sports marketing, to make a run at baseball.
