Los Angeles' Adrian Gonzalez was ruled out at home attempting to score after a fielder's choice and throwing error by Cubs shortstop Starlin Castro.
Dodgers manager Don Mattingly came out to argue with home-plate umpire Jim Wolf, but the review confirmed that catcher Welington Castillo tagged out Gonzalez after receiving a relay throw from first baseman Anthony Rizzo.
The replay showed that Gonzalez did not touch the plate during his slide and that Castillo was not in violation of Rule 7.13. Mattingly said it was that rule he wanted to check on when he came out to argue.
"I was just checking the catcher. I wasn't challenging the call," Mattingly said.
In the third inning, Cubs manager Rick Renteria had a call overturned after he challenged whether Dodgers pitcher Dan Haren was safe at first.
Haren led off the inning, lining the ball to shallow right. Chicago's Nate Schierholtz threw the ball to first baseman Rizzo, who appeared to get his foot back in time to touch the base. Haren was originally called safe by first-base umpire Tony Randazzo.
But after a review, the call was overturned, and Haren was out.
After back-to-back reviews that went against the Dodgers, their replay luck started to turn in the top of the fifth inning. Rizzo hit a deep ground ball to third baseman Justin Turner and was ruled safe at first.
Mattingly challenged the ruling on the field, and after a review, the play was overturned.
In the sixth inning, the Dodgers had runners at first and second when Hanley Ramirez hit a grounder to third baseman Luis Valbuena. He threw to second baseman Arismendy Alcantara for the force. Alcantara then threw to Rizzo at first, but that was late. Yasiel Puig, who was on second, kept running and was called safe at home on a wild slide.
"The reason we did challenge was because we thought [Castillo] tagged him on the left hand," Renteria said.
It appeared catcher Castillo had tagged Puig on his arm before he touched the plate, but after a lengthy review, Wolf's call stood, and the Dodgers pulled within 8-2.
