The Los Angeles Dodgers clinched their seventh consecutive NL West title in fitting fashion, using two home runs by Corey Seager and a masterful pitching performance by Walker Buehler to beat the Baltimore Orioles 7-3 on Tuesday night. After the final out, the first team in the majors to clinch a playoff spot this season gathered at the mound for a subdued celebration that included a wardrobe change for a pending champagne celebration in the clubhouse. Los Angeles, coming off consecutive World Series losses to Houston and Boston and seeking its first title since 1988, will likely begin the postseason at Dodger Stadium on Oct. 3 against the NL wild-card team.
