When Adam Wainwright struck out Carlos Beltran to clinch the 2006 National League pennant for the St. Louis Cardinals, hearts broke all over Shea Stadium. But one fan in the third-base stands rejoiced.

“I jumped out of my seat,” said Jon Hamm, an actor and lifelong Cardinals fan. “I looked around, and I was literally like one of one, standing out with my big red Cardinal hat. I was like: Yes! Oh, I should sit down.”

Hamm was in New York on Friday to promote his movie “Million Dollar Arm,” which opens nationwide May 16. As Don Draper on “Mad Men,” he warbled a few bars of “Meet the Mets” on last week’s episode.

“I was very drunk,” Hamm said, laughing. “That might be on the Jumbotron.”

Hamm will soon begin filming the final episodes of “Mad Men,” but not before a stop in Pittsburgh on Sunday to see the Cardinals play the Pirates. His character in the film, the agent J. B. Bernstein, arranges a reality television show to find a baseball player in India. The winners, Dinesh Patel and Rinku Singh, signed professional contracts as relief pitchers for the Pirates. Singh remains with the organization as he recovers from an elbow injury.
