Question: Who is the wife of the Tigers pitcher who was name World Series MVP? Passage:The 2012 World Series was the championship series of Major League Baseball's (MLB) 2012 season. The 108th edition of the World Series, the series was a best-of-seven playoff between the National League (NL) champion San Francisco Giants and the American League (AL) champion Detroit Tigers; the Giants won in a four-game sweep. This marked the Giants' seventh World Series title in franchise history, their second in San Francisco (they won five in New York), and their second in a three-year period (20102012). Their World Series sweep was the first by an NL team since the Cincinnati Reds swept the Oakland Athletics in the 1990 series and the first NL sweep not by the Reds since 1963, when the Los Angeles Dodgers swept the New York Yankees. This was also the first World Series since 1988 to feature both of that year's League MVPs (Miguel Cabrera for the AL and Buster Posey for the NL). The Giants' Pablo Sandoval, who in Game1 tied a record by hitting three home runs in one World Series game, two off Tigers' ace pitcher Justin Verlander, was named the World Series Most Valuable Player (MVP).

Question: Which countries comprised the alliance that conquered and occupied Greece?
