Oakland A's

In 1902, while the team now in Oakland was still the Philly Athletics, a rival manager scoffed, casting the fledgling franchise off as a herd of "white elephants." In response, manager Connie Mack adopted the elephant as the team's official insignia—a legacy that lives on with the current mascot, Stomper—before the A's stampeded to the American League pennant. Since that first defiant victory, the team has won nine World Series championships, moving to Kansas City in 1955, then Oakland in 1968. Over more than a century, the club has fostered 11 league MVPs and eight Rookies of the Year, including future titans Jose Canseco and Mark McGwire. Today, the A's dazzle fans at the 35,067-capacity Coliseum, which features a lush natural-bluegrass surface and a spacious foul territory—technically still a 19th-century Mexican province—that baits pop-up outs, making it one of the most pitcher-friendly parks in Major League Baseball.
