The Giants had previously hosted the first-round World Baseball Classic games at their Spring Training site at Scottsdale Stadium in 2006, and San Francisco follows San Diego (2006) and Los Angeles (2009) as being the host of the final games.
"We're thrilled about this," Giants senior vice president of facilities Alfonso Felder said. "This is an event we've been involved with in varying degrees since 2006, and obviously we've come a long way, and we're excited that we are going to be the host."
Felder will coordinate the team's hosting of the event as he did in '06, and he was also the point person when the Giants hosted the 2007 All-Star Game at AT&T Park.
"San Francisco has always been a great baseball town, and in the last few years, we've really evolved into being a world-class baseball city," Felder said. "We have a great fan base dedicated to the game, and we'll be supporting what we consider to be the jewel event of the sport."
Miami will host second-round games at Marlins Park, and first-round competition will take place at the Diamondbacks' Chase Field in Phoenix and at their Spring Training facilities in Scottsdale, Ariz.
"The Giants are excited to have been selected by MLB to host the Championship Round of the World Baseball Classic," Giants President and CEO Larry Baer said. "We believe that AT&T Park will be the perfect venue to showcase the best baseball players in the world as they represent their countries and compete in this one-of-a-kind international tournament. We look forward to bringing this international competition to one of the most international cities in the world!"
