LOS ANGELES -- 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 savor the moment.

The Dodgers clinched the NL's top postseason seed and eighth straight division title with a 7-2 victory over the Oakland Athletics on Tuesday. They are the third team to win at least eight straight division titles, joining the Atlanta Braves (14 straight from 1991 to 2005) and New York Yankees (nine straight from 1998 to 2006).

"To fast-forward a couple months and be crowned NL West champs is a credit to everyone. It should never be taken for granted,'' Roberts said. "Truth be told, a lot of guys didn't know we could clinch. We were responsible, but I let it know that it has to be appreciated.''

The Dodgers, who own the best record in the majors at 39-16, were the first team in baseball to clinch a playoff berth on Sept. 16. They will open postseason play on Sept. 30 by hosting every game in a best-of-three series against the No. 8 seed.

Los Angeles came into the day with a magic number of two and got help with the Angels' 4-2 victory over the San Diego Padres.

Instead of a wild celebration on the mound after Jake McGee struck out Sean Murphy for the final out, players briskly walked out of the dugout to celebrate with teammates. Everyone grabbed a division clinching shirt and cap before heading to the mound for a group photo.

The clubhouse celebration was also muted. Champagne was involved, but it was players toasting one another with a glass instead of being showered in it.

"We talked about it -- instead of dumping stuff on people. It's a moment you need to celebrate, and we did,'' said Corey Seager, who had three hits and one of Los Angeles' four home runs Tuesday. "It stinks not being able to do champagne and beer showers because some of the younger guys haven't been able to experience that.''

Max Muncy, Chris Taylor and A.J. Pollock also went deep for Los Angeles, which leads the majors with 104 home runs.

"This whole year has been weird. There's no other way to describe it,'' Muncy said. "It's sad not to be celebrate as usual, but we know there is a lot more at stake.''

Dustin May went five innings and allowed two runs on three hits. The 22-year-old righty set a team record by not allowing more than three earned runs in any of his first 13 career starts, which includes 10 this season.

Seager tied it at 1 in the first with an RBI single and led off the fifth with a drive to center off T.J. McFarland to extend L.A.'s lead to 6-2.

Muncy gave the Dodgers a 3-2 lead in the third inning with a two-run homer. Taylor and Pollock extended it with solo shots in the fourth off Oakland starter Frankie Montas.

Cody Bellinger added two hits for the Dodgers, including an RBI single with the bases loaded in the seventh.

Dodgers third baseman Justin Turner was scratched from the lineup less than an hour before first pitch because of left hamstring discomfort. He came off the injured list on Sept. 15 and has not played in the field since Aug. 28.

Joc Pederson was in the lineup at DH after missing five games while on the family emergency medical list. Roberts said before the game that he wasn't sure if Pederson will remain with the team for the entire postseason.
