The Giants have won their first World Series since moving to San Francisco. Prior to that, the team was located in New York. The New York Giants lost to the Boston Red Sox in the 1912 World Series and would have played them in 1904 had there been a World Series. The Giants last won the World Series against their then-crosstown rivals the Yankees.
Edgar Renteria was named the World Series MVP. Renteria played briefly for Boston in 2005. Expect a post devoted to Edgar Renteria at a later date, but it's kind of a negative post and I would prefer not to criticize at this time.
