McGwire, Sosa could ride home-run hype as ad team.

This article reports on the possibility of baseball players Mark McGwire and Sammy Sosa being paired up to endorse products if both break baseball player Roger Maris's record of the most homeruns in a single baseball season. MasterCard International last weekend joined Anheuser-Busch Cos. Inc. and Pepsi-Cola Co. in leveraging the home-run hype in ads. But MasterCard's spot, created by McCann-Erickson Worldwide of New York, is the first one to feature both McGwire and Sosa. Mark Leonard, president of Integrated Marketing Solutions and agent for Chicago Cub Sosa, said that the MasterCard pairing prompted him to call the agent for Saint Louis Cardinal's McGwire to talk about working together on other projects.
