Harrison Bader tripled and homered to help the St. Louis Cardinals clinch a postseason berth on the final day of the regular season with a 5-2 win over Milwaukee, and the Brewers also earned a playoff spot Sunday via help on the West Coast moments later.

St. Louis (30-28) will be the fifth seed in the NL and open a three-game wild-card series at San Diego on Wednesday. By winning, the Cardinals avoided having to travel to Detroit for two makeup games Monday. St. Louis finished the regular season with 23 games in 18 days as it made up a slew of postponements caused by a coronavirus outbreak in the clubhouse.

The Brewers (29-31) locked up the eighth seed and a third consecutive postseason berth after the Padres beat San Francisco 5-4 in a game that ended about 15 minutes after St. Louis' victory. The Giants finished with an identical record as the Brewers but lost out on a tiebreaker due to an inferior intradivision record.

Milwaukee will face the top-seeded Dodgers in Los Angeles in a three-game series that also starts Wednesday.

Cardinals starter Austin Gomber allowed one run, one hit and two walks and struck out three over four innings.

Giovanny Gallegos (2-0), Genesis Cabrera and Alex Reyes combined to pitch the final five innings. Reyes got his first save.

Brett Anderson (4-4) surrendered a triple to Bader and a walk to Tyler O'Neill to start the third inning before departing with a blister on his left index finger. Anderson opened the season on the injured list with a blister on the same finger and did not make his debut until Aug. 3.

Freddy Peralta replaced him a day after being activated from the paternity list, and O'Neill promptly stole second. Kolten Wong then hit a line drive off Peralta's leg that Peralta threw into right field to score Bader and O'Neill.

Paul Goldschmidt and Paul DeJong each added RBI singles to push the St. Louis lead to 4-0.

This will be the fourth postseason series between St. Louis and San Diego, who faced each other in 1996, 2005, and 2006 in the Division Series.
