Regularly voted one of the top places in America to watch a ballgame, beautiful AT&T Park hosts a Bay Area showdown as the San Francisco Giants take on cross-bay rivals the Oakland Athletics. After winning two of the last four World Series championships, the Giants are going for it again, having battled their way to first place in the National League West. They'll be aided in that pursuit by trusty veterans such as Buster Posey and Pablo Sandoval as well as exciting newcomers like Tyler Colvin. For their part, the A's have been making a big noise with their bats and currently lead the American League West, largely thanks to up-and-coming star Yoenis Céspedes.
