San Francisco Mayor Ed Lee and Detroit Mayor David Bing Wednesday bet a day of community service in the winner’s city of the World Series between the Giants and the Tigers.

The losing mayor will travel to the winning city for a day of community service and a tour of different companies based in the respective cities.

If the San Francisco Giants win, Bing will come to Bay Area and spend a day playing baseball with young people in the Junior Giants program and then tour several companies involved in high tech innovation.

If the Tigers win, Lee will travel to Detroit to tour the Chevy Volt factory and learn more about Detroit’s leadership in the electric vehicle market. He will also participate in a day of service benefitting the youth of Detroit.

“San Francisco is completely awash in Giants fever,” said Lee. “It seems that everyone in the City is wearing Giants Orange, celebrating the improbable National League champions … The San Francisco Giants are truly the comeback kids – this team never quits.”

Likewise, Bing was among his teen’s strongest supporters.

“The Detroit Tigers have brought plenty of excitement and a lot of pride to the people of Detroit, the entire metro area and the state of Michigan during this post-season,” he said in a prepared statement. “The Giants have had great success, but we’ve already proven we can handle any team out of the Bay Area.”

The Tigers edged the Oakland Athletics three games to two in the opening round of the American League playoffs.

The San Francisco Giants are making their second World Series appearance in three years, following come-from-behind victories in consecutive playoff series against the Cincinnati Reds and St. Louis Cardinals.

The Giants’ road to the 2012 World Series included six do-or-die elimination games, all of which the team won in dramatic fashion.
