MLB Underdog Picks for August 5: Will The Marlins Keep Their Hot Streak?

With a full 15-game slate in the MLB odds boards tonight, I’ve locked three underdog wagers that you’ll want to consider using our AI Model. Let’s build the bankroll!


Houston Astros vs. Miami Marlins

Tuesday, August 05, 2025 – 6:40 PM EDT at loanDepot Park

The Miami Marlins are currently slight underdogs at home against the Houston Astros tonight. Ultimately, the Marlins have been one of the hottest teams in baseball over the last month or so. You can find them at -106 on the moneyline right now. That said, the AI Model believes the Astros and Marlins will tie, 3.9-3.9. Take the home underdogs.

Astros Bullpen Game Gives Marlins the Edge

The Houston Astros still haven’t confirmed a pitcher for tonight’s game, but it’ll likely be a bullpen game with Kaleb Ort getting the start.

Ort has walked 19% of his last 21 righties. He’s also allowed a .200 ISO to his last 15 lefties. Right now, the Marlins’ lineup is filled with lefties who have shown off power. Xavier Edwards, Kyle Stowers, and Jakob Marsee are all lefties to look out for tonight against the Astros.

Meanwhile, Cal Quantril will get the start for the Marlins. The veteran righty has held his last 79 batters to a .092 ISO and wOBA of .231. It’s all starting to click for him. He’s struck out just 19% of batters, but he’s also held his last 79 batters to 21.3% of line drives.

The Marlins look much better on paper. Let’s take the home underdog at -106 in this game.

The Pick: Marlins ML (-106) at Caesars


Milwaukee Brewers vs. Atlanta Braves

Tuesday, August 05, 2025 – 7:15 PM EDT at Truist Park

The AI Model suggests the Brewers will add a 4.6-3.0 win over the Braves tonight. Forget the moneyline. Instead, think about the Brewers at -1.5 at +114 odds. The AI Model expects the Brewers to cover this!

High Strikeouts For Freddy Peralta

The Milwaukee Brewers are set to pitch Freddy Peralta tonight. He’s a righty who has allowed a .167 ISO and wOBA of .311 over the last 30 days. Still, he’s dominated against righties and has added a high strikeout rate against lefties.

The Braves’ projected starting lineup has struck out close to 25% of the time against righties, which means it’s likely Peralta adds a high rate of strikeouts tonight for the Brewers.

On the other hand, the Atlanta Braves will run with Joey Wentz, a lefty who has allowed 37.5% of fly balls against his last 67 batters faced. He’s been very lucky, holding those 67 batters to a .184 BABIP, but if balls continue to get lifted, that BABIP should rise, especially against the Brew Crew.

I’m on the Brewers at -1.5 (+114). There’s some good value there.

The Pick: Brewers -1.5 (+114)


San Diego Padres vs. Arizona Diamondbacks

Tuesday, August 05, 2025 – 9:40 PM EDT at Chase Field

Our AI Model really loves the Arizona Diamondbacks tonight. It thinks the Diamondbacks will earn a 7.0-3.6 win over the San Diego Padres. However, Arizona is +115 on the moneyline at home. This is a steal!

Arizona’s Lefties Can Slug!

The Arizona Diamondbacks will take on Yu Darvish of the Padres. Ultimately, Darvish is a household name who has struggled against lefties over the last month. He’s actually struck out only 10.3% of lefties and has walked 15.5% of lefties over the last 30 days.

In addition, he’s given up a 9.5% barrel percentage and has earned just 8% of swinging strikes in that time frame.

The Diamondbacks have lefty bats like Corbin Carroll, Geraldo Perdomo, Alek Thomas, and Ketel Marte. All of these guys can take advantage.

Meanwhile, the Diamondbacks will send out Ryne Nelson, a righty who has also struggled against lefties. That said, he’s facing a Padres lineup where lefties have hit just a .156 ISO against righties over the last month.

Let’s ride with the Diamondbacks’ moneyline at +115.

The Pick: Diamondbacks ML (+115)
