"Bill Mazeroski, home-run-hitting hero of the Pirates' World Series victory, has started reaping the benefits of his long hit—and at advanced prices, too. The West Virginia second baseman posed a problem last night to the celebrity panel of "I've Got a Secret". And next month, he will be a mystery guest on another guessing show (and he's keeping the name of the program his secret for the time being). Before the second pitch of the ninth inning of the seventh World Series game, Mazeroski could have demanded a couple of hundred dollars for a television appearance. But, according to his agent, Pittsburgher Frank Scott, Mazeroski will receive $1,000 plus expenses for his mystery-guest stint (plus, no doubt, whatever figures come up on the flip cards). "I guess I'd have to say Mazeroski is the most in demand," said Scott, a Pittsburgher who started his sports career as a student at Pitt during the Jock Sutherland era. Scott, based in New York, has at least five other Pirates in his stable, in addition to many Yankees. Among other assignments for the World Series hero is a tobacco chew endorsement for a television commercial."
