The Arizona Diamondbacks became the first team to hit four home runs in a postseason inning and held on for a 4-2 win over the Los Angeles Dodgers to finish a stunning sweep and reach the NL Championship Series on Wednesday.

Geraldo Perdomo, Ketel Marte, Christian Walker and Gabriel Moreno went deep off Dodgers starter Lance Lynn in the third inning for a 4-0 lead.

That would be all the offense Arizona would need to eliminate the NL West champion and 100-win Dodgers and move into the NLCS for the first time since losing to Colorado in 2007.

The sixth-seeded Diamondbacks improved to 5-0 in these playoffs.

Rookie Brandon Pfaadt worked the first 4 1/3 innings without allowing a run before Joe Mantiply got the next four outs.

Ryan Thompson gave up a pair of runs in the seventh, but Andrew Saalfrank quelled the rally and Kevin Ginkel fanned two in the eighth.

Paul Sewald pitched the ninth for his fourth postseason save in as many opportunities.

Los Angeles scored two runs in every game of the series and hit one home run to Arizona’s nine.

Former MVPs Mookie Betts and Freddie Freeman combined to go 1 for 21 without an RBI in the series.

Astros oust Twins for another trip to ALCS

Jose Abreu and Michael Brantley homered, and the Houston Astros topped the Minnesota Twins 3-2 to reach the AL Championship Series for a seventh consecutive season.

Abreu’s two-run blast in the fourth off reliever Caleb Thielbar scored Yordan Alvarez and gave the Astros a 3-1 lead they would not relinquish.

Abreu had three homers and eight RBIs in the four-game series, while Alvarez had four home runs and six RBIs.

Houston will host in-state rival Texas in Game 1 of the ALCS on Sunday, with three-time Cy Young winner Justin Verlander likely on the mound for the Astros.

Jose Urquidy limited the Twins to two runs – both on homers - and three hits over 5 2/3 innings with one walk and six strikeouts.

Hector Neris and Bryan Abreu combined for five strikeouts over 2 1/3 hitless innings and former Twin Ryan Pressly struck out the side in the ninth.

Royce Lewis hit his fourth home run of this postseason and Edouard Julien also went deep for the Twins, who managed just three runs and six hits in two home games in this series.

Harper hits 2 of Phillies’ 6 home runs in win

Bryce Harper and Nick Castellanos each homered twice, and the Philadelphia Phillies rolled to a 10-2 rout of the Atlanta Braves for a 2-1 lead in their NL Division Series.

Brandon Marsh and Trea Turner also went deep for the Phillies, who can advance to the NL Championship Series for the second consecutive season with a win at home Thursday.

Aaron Nola allowed two runs and six hits over 5 2/3 innings and four relievers held Atlanta scoreless the rest of the way.

The Phillies scored six runs in the third to knock out Bryce Elder, with Castellanos leading off with a home run.

After Marsh and Turner singled, Harper launched a 2-1 pitch deep into the seats in right for a 4-1 lead.

J.T. Realmuto capped the uprising with a two-run double against Michael Tonkin.

Harper added a solo homer off Brad Hand in the fifth and Turner’s blast an inning later made it 8-1.

Harper has nine playoff home runs in 22 games over the past two seasons, with five coming against Atlanta.
