That rivalry may not be between the Red Sox and Yankees, but between two teams that are gearing up for another division race in the NL West, and who are also playing each other this weekend, the Giants and the Dodgers. Both the Yankee-Red Sox and the Dodger-Giant rivalries have had moments of intense competition, memorable games and pennant races, and genuine rancor between the two teams. However, the degree of competition and balance between the two rivals has been consistently stronger between the two NL rivals.
