The current betting odds have the Cubs listed as a favorite in this game according to Draftkings Sportsbook. The Cubs have looked good in their games this season with their 46-38 record overall which has them right near the top of the NL Central. They have looked good in their own ballpark too with their 23-17 home record this season. Meanwhile, the Padres have looked good in their games this season with their 43-39 record overall which has them right near the top of the NL West. They have been a good road team too with their 20-18 road record this year. The Padres are 6-4 in their last 10 games and they have looked good lately, but they just lost their last series to the Dodgers and they still have one of the worst offenses in MLB this year. The Cubs have one of the best offenses in the league though, and after going through a big slump over the last few weeks, they are finally starting to break out of it as they are 8-2 in their last 10 games. The Cubs are going with Boyd in this one and he hasn't looked good this season. He is 2-1 with a 5.02 ERA, but lately he has looked a lot better. He is coming off a great start in which he gave up no runs and even his team has won 2 games in a row now with him starting. The Padres are going with Sears in this one and he has looked good this year. He is 1-0 with a 3.18 ERA and has only made 1 start this season. He gave up 2 earned runs in that start and his team won it, but he also faced a Braves lineup that hasn't been putting up a lot of runs lately. He is going to have more trouble in this one with the Cubs getting hot on offense again, so look for the Cubs to take advantage of this pitching matchup with Boyd also pitching better lately. The best way to place a bet here is on the Cubs to win this game.

“He just kind of lost the strike zone.” - Craig Stammen on Michael King after his team’s loss against the LA Dodgers in their game on Sunday. 

“Everybody stood out. But Bryse Wilson would be the guy that we got an incredible effort from. Obviously, that’s a very good offense and he got 13 outs for us and didn’t give up a run, made some big pitches to some good hitters.” - Craig Counsell after his team’s win against the Brewers in their game on Sunday.
