Although the San Francisco Giants do have the larger fanbase amongst the two Bay Area major league teams, one significant point that Oakland Athletics fans can take serious pride in is having secured more locally won World Series championships. The Giants have three (2010, 2012 and 2014) while the A’s have lifted the Commissioner’s Trophy in Oakland on four occasions (1972, 1973, 1974 and 1989), including famously beating the Giants in the 1989 Fall Classic.
