The current betting odds have the Braves listed as an underdog in this game according to Draftkings Sportsbook. The Braves have looked great in their games this season with their 88-62 record overall which has them right at the top of the NL East with one of the best records in MLB. They have been a good road team too with their 37-35 road record this year. Meanwhile, the Cubs have looked really good in their games this season with their 83-67 record overall which has them right near the top of the NL Central. They have looked great in their own ballpark too with their 43-32 home record this season. The Cubs have one of the best offenses in MLB, but they are 5-5 in their last 10 games and their pitching has been terrible lately. The Braves haven't looked any better lately as they are also 5-5 in their last 10 games, but they do have a good offense too and their pitching has looked a lot better. Perez is on the mound for the Braves in this one and he has looked good this season. He is 8-9 with a 3.08 ERA and he hasn't been giving up many runs lately. He is coming off another great start giving up no runs which has been a common theme for him and the team has been having success with him too, winning 2 of their last 3 games with him starting. The Cubs are going with Gausman in this one and he hasn't looked great this season. He is 9-12 with a 4.60 ERA and he has had a lot of trouble this year. The team has been having success with him lately, winning 4 of their last 5 games with him starting, but he did give up 6 earned runs in his last start and that has been a common theme for him. The bullpen has had a lot of trouble for the Cubs lately too, so look for the Braves to take advantage of this pitching matchup. The best way to place a bet here is on the Braves to win this game.

“We have to have tunnel vision and just keep our heads down, and keep going and stack up wins; take care of our own business. We’ve done a nice job in the division. We’ve done a nice job against Philly [and] against playoff teams. We’ve played really well. We have a couple of tiebreakers in our favor. Overall, it was a good weekend.” - Walt Weiss after his team’s loss against the Phillies in their game on Sunday.
