Wrapping up an NL West title has become routine for the Los Angeles Dodgers, but in a year in which no one was sure three months ago if there would be a baseball season, manager Dave Roberts wanted his team to still savor the moment. The Dodgers clinched the NL's top postseason seed and eighth straight division title Tuesday night with a 7-2 victory over the Oakland Athletics. The Dodgers, who own the best record in the majors at 39-16, were the first team in the majors to clinch a playoff berth on Sept. 16.
