With two runs batted in and outstanding defense in center field, Pete Crow-Armstrong helped the Chicago Cubs secure a 6-3 win against the Los Angeles Dodgers on Tuesday, benefiting from three costly errors by the Dodgers in the eighth inning.

The Cubs capitalized with five runs in the eighth, aided by throwing mistakes from catcher Austin Barnes and center fielder Tommy Edman, along with a fielding misstep from Enrique Hernandez.

Shota Imanaga (13-3) played a crucial role for the Cubs, pitching seven innings with three runs allowed on seven hits while striking out four without any walks.

Imanaga’s performance followed his recent start, which was a combined no-hitter against the Pittsburgh Pirates on September 4. Nate Pearson and Porter Hodge were called in after him and pitched one scoreless inning each, with Hodge achieving his fifth save, aided by a crucial catch from Crow-Armstrong.

Nico Hoerner and Seiya Suzuki each contributed three hits and an RBI for the Cubs (75-70), keeping them four games behind the Atlanta Braves and the New York Mets in the race for the last National League wild-card spot.

Tommy Edman hit two home runs, and right-hander Yoshinobu Yamamoto struck out eight batters in his return from a shoulder injury, but the Dodgers lost for the fourth time in their last six games, leading the National League West.

Max Muncy also homered for the Dodgers, who now have a 4.5-game lead over the second-place San Diego Padres.

The Dodgers were ahead 3-1 in the eighth inning when their defense fell apart. Barnes’ throwing error on a ground ball hit by Dansby Swanson allowed a second runner to reach base with no outs. Suzuki’s single brought in a run, and another run scored as Swanson crossed the plate due to Edman’s throw getting away, leveling the score at 3-3.

Chicago took the lead at 4-3 on a Michael Busch fielder’s choice, which resulted in another error from Hernandez. Hoerner followed with an RBI double, and Crow-Armstrong drove in the final run with a groundout.

Edman’s home runs in the second and fourth innings gave the Dodgers an early 2-1 edge. This marked Edman’s first home runs with the Dodgers after being traded from the St. Louis Cardinals in July.

Muncy extended the Dodgers’ lead to 3-1 with his 13th home run of the season in the fifth inning.

The Dodgers had a chance in the ninth with a runner on third and two outs when Crow-Armstrong made a game-ending play, robbing Muncy of a home run. He also made two other sliding catches in right-center field during the game.

Evan Phillips (3-1) suffered the loss, giving up four unearned runs in the eighth inning.

Yamamoto, in his comeback start since June 15, allowed just one run on four hits with no walks over four innings.
