Anthony Rizzo homered and had three hits, Jason Heyward went deep and drove in four and the Chicago Cubs beat the New York Mets 14-6 on Thursday night.
Chicago's offense helped overcome a shaky debut by pitcher Jen-Ho Tseng to complete a three-game sweep.
The Cubs outscored the Mets 39-14 this week after being outscored 20-3 in a weekend three-game sweep by the Milwaukee Brewers.
Kris Bryant added two RBIs as the Cubs extended their NL Central lead to three games over Milwaukee and St. Louis, with the Cardinals coming to Wrigley Field for three games this weekend.
Tseng threw behind the first batter he faced, fell down while covering first base on the second batter for an error and later hit a batter with a pitch in the first inning.
The Taiwanese 22-year-old went three innings, giving up five runs and five hits with six strikeouts. Tseng was Chicago's minor league pitcher of the year, going 13-4 with a 2.54 ERA in 24 starts for Double-A Tennessee and Triple-A Iowa.
Mike Montgomery and Brian Duensing (1-1) followed Tseng with two scoreless innings each.
Seth Lugo (6-5) was charged with eight runs, seven earned, with nine hits and a walk over three innings.
The Mets took a 5-3 lead in the third inning on back-to-back home runs by Dominic Smith and Travis d'Arnaud.
Consecutive RBI doubles by Jon Jay, Bryant and Rizzo highlighted a five-run fourth inning as the Cubs rallied with nine straight runs.
One night after knocking in six off the bench, Albert Almora Jr. had a two-run, pinch-hit double in the sixth. Heyward added a three-run home run later in the inning to make it 14-5.
Tomas Nido had his first career hit and RBI for the Mets in the ninth.
Cubs manager Joe Maddon donated $25,000 to Hurricane Irma relief efforts in Florida through his Respect 90 Foundation.
The former Tampa Bay Rays manager lives in Florida with his wife, Jaye. Maddon said he was approached to help by the Salvation Army.
Maddon has a restaurant, Ava, in Tampa, Florida, that delivered meals on Thursday and will again Friday to the Salvation Army.
"This is our small attempt to help out," Maddon said.
Cubs catcher Taylor Davis, 27, also made his first career start. Maddon said he wanted a familiar look behind the plate for Tseng, who played with Davis in Iowa.
