LOS ANGELES (Interstat) — Brandon Pfaadt pitched six effective innings and catcher James McCann drove in five runs with a pair of home runs as the Arizona Diamondbacks routed the Los Angeles Dodgers 9-2 on Saturday night at Dodger Stadium.

Pfaadt allowed two runs on six hits over six innings, striking out four and walking none to improve to 3-1. He retired the first 10 batters he faced and faced only one serious jam in the bottom of the sixth after Arizona had built a 6-0 lead. The right-hander gave up three straight one-out singles that produced two runs before he struck out Max Muncy and got Kyle Tucker to line out.

Yoshinobu Yamamoto took the loss for Los Angeles, dropping to 9-6. The right-hander allowed six runs on four hits over five-plus innings. He walked four and struck out five but was undone by a five-run sixth inning in which Arizona sent nine batters to the plate.

The Diamondbacks took a 1-0 lead in the fourth inning when Gabriel Moreno walked, moved to third on a single by Max Kepler and scored on a groundout by Tim Tawa. They broke the game open in the sixth.

Geraldo Perdomo walked to lead off the inning and Corbin Carroll struck out. Moreno singled to put runners at the corners and Kepler drove in Perdomo with a sacrifice fly to center field. Tawa followed with an RBI double, scoring Moreno. Yamamoto then intentionally walked Nolan Arenado, bringing McCann to the plate.

McCann launched a 1-1 pitch over the left-field wall for a three-run home run, his first of the season, extending the lead to 6-0. It was the second home run of his career and capped Arizona’s biggest inning of the night.

The Dodgers answered in the bottom half. Tommy Edman doubled to lead off and scored on a single by Andy Pages. After Freddie Freeman singled, Mookie Betts drove in Pages with a base hit to make it 6-2. Pfaadt then retired Muncy and Tucker to end the threat.

Arizona added a run in the seventh when Perdomo was hit by a pitch, moved to third on a walk and scored on another sacrifice fly, this time by Kepler. McCann led off the eighth with his second home run of the game, a solo shot to left-center field, and Arenado had homered earlier in the inning on a solo blast to left field, his 12th of the season.

McCann finished 2-for-4 with five RBIs and two runs scored. Arenado went 1-for-4 with a walk, a home run and an RBI. Tawa had two hits, including a double, and drove in a run. Kepler also had two hits and two RBIs.

For Los Angeles, Betts had two hits and an RBI. Edman and Freeman each had one hit. Shohei Ohtani went 1-for-3. The Dodgers managed only six hits and struck out eight times.

The game, which was played in front of 48,102 fans at Dodger Stadium, lasted 2 hours, 44 minutes.

Arizona improved to 48-47 with the victory, its second straight over the Dodgers after a 9-3 win Friday night. The Diamondbacks have won five of their last seven games. Los Angeles fell to 61-35, losing its second consecutive game after dropping three of four to Colorado earlier in the week.

The Diamondbacks took advantage of shoddy Los Angeles defense in the third inning when a throwing error by third baseman Max Muncy allowed James McCann to reach base, but Arizona failed to score. They did not waste opportunities later, putting up crooked numbers in the sixth and eighth innings.

Pfaadt’s performance continued a strong stretch for Arizona’s rotation. He allowed only three baserunners through the first four innings and did not give up a hit until Ohtani singled with one out in the fourth. The Dodgers loaded the bases in that inning on a single by Pages and a forceout, but Pfaadt got Betts to pop out and Muncy to ground out.

The Diamondbacks outhit the Dodgers 9-6 and drew six walks. Los Angeles had two walks but left five runners on base.

Arizona manager Torey Lovullo used four relievers after Pfaadt exited, none facing more than four batters, and they combined for three scoreless innings. Joe Mantiply, Kevin Ginkel, Justin Martinez and Paul Sewald each worked a clean inning, with Sewald striking out the side in the ninth.

The Dodgers’ bullpen allowed three runs over four innings after Yamamoto departed. Michael Grove, Ryan Brasier and Alex Vesia each gave up at least one hit.

Arizona’s victory evened the season series at four wins apiece heading into the final game of the four-game set Sunday. The teams had split a four-game series at Chase Field earlier this season, with the Dodgers taking the first two and the Diamondbacks the last two.

Interstat’s game simulator had projected a final score of Los Angeles 7, Arizona 4, and its ELO system gave the Dodgers a 68.40 percent probability to win. Los Angeles was installed as a pregame favorite with a spread of minus-1.5. The combined total of 11 runs went under the over-under line of 8.5.
