The current betting odds have the Reds listed as a slight favorite in this game according to Draftkings Sportsbook. The Reds haven't looked great in their games this season with their 58-62 record overall which has them right near the bottom of the NL Central. They haven't looked great in their own ballpark either with their 29-31 home record this season. Meanwhile, the Marlins have looked good in their games this season with their 62-60 record overall which has them right in the middle of the NL East. They have been a terrible road team though with their 24-35 road record this year. The Marlins have been really up and down all season and after going through a bit of a hot streak recently, they are now 5-5 in their last 10 games. The Reds haven't been great for a lot of the year themselves, but lately they have been getting hot as they are 6-4 in their last 10 games and putting themselves right back in the NL Wild Card race. The Reds are going with Singer in this one and he hasn't looked great this season. He is 5-11 with a 4.66 ERA, but lately he has looked a lot better in his starts and has also pitched better at home. He did give up 3 earned runs in his last start and the team has lost 2 of their last 3 games with him starting now, but he will be looking to bounce back at home and the Reds offense has been putting up runs lately. The Marlins are going with Gusto in this one and he hasn't looked any better this season. He is 0-3 with a 4.78 ERA and the team hasn't had a lot of success with him this year. He only gave up 2 earned runs in his last start and the team has won 2 of their last 3 games with him starting now, but the bullpen hasn't been in great shape and the offense has been all over the place too. The Reds are the hotter team entering this series and they do have a bit of an edge here with how much better Singer has looked at home this year. The Marlins have also looked like a completely different team in road games. The best way to place a bet here is on the Reds to win this game.
