BALTIMORE — The Los Angeles Dodgers clinched their seventh consecutive National League 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 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.

This is the earliest that Los Angeles (94-52) has ever clinched the division, both in terms of date and games. The 1977 team did it in Game 151, and the 2013 club clinched on Sept. 19.

Though an Arizona loss to the New York Mets would have clinched it for the Dodgers, Los Angeles emphatically took care of business on its own. Seager homered with two on to cap a four-run first inning against Ty Blach (1-3) and added a two-run drive in the third for a 6-0 lead.

Gavin Lux hit his first career homer in the fifth to increase the Dodgers’ NL record for long balls in a season to 258.

Buehler (13-3) limited last-place Baltimore to four hits over seven shutout innings. He struck out 11.

Brewers 4, Marlins 3: MIAMI — Christian Yelich broke his right kneecap on a foul ball and will miss the rest of the regular season, an injury that overshadowed Milwaukee’s win over Miami. The Brewers did not say whether the reigning NL MVP might be able to return for the playoffs that begin Oct. 1 if they make it that far. Yelich will return to Milwaukee on Wednesday for further evaluation. Milwaukee, which won its fifth in a row, began the day two games behind the Chicago Cubs for the second NL wild-card spot. Yelich fouled a ball off his leg in the first inning.
