The current betting odds have the Braves listed as a favorite in this game according to Draftkings Sportsbook. The Braves have looked great in their games this season with their 33-16 record overall which has them right at the top of the NL East with the best record in MLB. They have been a great road team too with their 17-8 road record this year. Meanwhile, the Marlins haven't looked good in their games this season with their 22-27 record overall which has them in the bottom half of the NL East. They have looked a lot better in their own ballpark though with their 15-13 home record this season. The Marlins have looked a lot better at home all year, but they are 5-5 in their last 10 games while the Braves are 7-3 in their last 10 and have been rolling with one of the best road records in the league. Alcantara is starting for the Marlins in this one and he has looked good this season with the team having a ton of success with him too. He is 3-2 with a 3.53 ERA and the team has won 2 games in a row now with him starting. He is off a great start in which he gave up no runs too, but the Braves also have some solid pitching and they definitely have the offensive advantage. Strider is on the mound for the Braves in this one and he has looked great this year. He is 1-0 with a 2.45 ERA and the team has been having a lot of success with him too. He only gave up 1 earned run in his last start which has been a common theme for him and the team has won 3 games in a row now with him starting. Strider has not only been the better starter this year, but the Braves also have one of the best offenses in MLB and they are going to use that to their advantage, especially when the Marlins bullpen comes into play. The best way to place a bet here is on the Braves to win this game.
