Team Analysis
St. Louis Cardinals
The Cardinals’ 0-5 record across their last five games highlights a slump, but their season-long output still reflects a lineup capable of rebounding quickly. Away from home, their 26-34 record shows inconsistency, yet their offense has remained above league average in run production over the past 10 games. Alec Burleson’s steady hitting and Willson Contreras’ run-driving ability give them multiple threats capable of breaking open a game, especially against a Marlins pitching staff that has struggled to contain opponents.
While the losing streak signals urgency, the Cardinals’ 61-63 overall record reveals their ability to stay competitive in tight contests. Ivan Herrera’s consistency adds an additional layer of reliability to the batting order, helping sustain pressure even when the team is not at full rhythm. With the Marlins’ pitching staff producing a higher ERA, the Cardinals’ balanced hitting approach is positioned to translate into a much-needed rebound performance on the road.
- Batting Average: 0.25
- Total Runs Scored: 537
- Home Runs: 118
- OBP: 0.318
- SLG: 0.388
- OPS: 0.706
- ERA: 4.25
- WHIP: 1.29
Away Record: 26-34 • Home Record: 35-30
Last 5 Games: 0-5 (4.0 RPG)
Last 10 Games: 4-6 (3.7 RPG)
Miami Marlins
Miami Marlins’ 2-3 record across their last five games, paired with a 3-7 stretch over their last 10, reveals their inability to string together consistent results. Kyle Stowers has been a bright spot with reliable power, but the team’s overall rhythm remains uneven. At home, their 28-31 mark reflects mediocrity, and late-game execution has often kept them from turning offensive production into sustained wins.
Agustin Ramirez provides some mid-order strength, and Xavier Edwards has added contact reliability, but neither has been enough to mask the Marlins’ flaws in high-leverage scenarios. Their pitching inefficiency continues to place pressure on the lineup, and while scoring 5.6 runs per game in the last five hints at offensive life, their defensive lapses undermine that progress. Against a Cardinals team seeking to snap a losing streak, Miami Marlins’ inconsistency at home makes them a vulnerable favorite.

Miami Marlins’ last 10 games have averaged 9.6 combined runs, with 4 games clearing the same number of 8.
Moneyline Betting Prediction
The Cardinals’ overall balance and stronger statistical foundation give them the sharper edge despite their recent skid. Their ability to generate runs through multiple contributors and exploit Miami Marlins’ higher ERA positions them well for a bounce-back performance. With the Marlins struggling to convert offensive bursts into wins, the Cardinals are the side with the more reliable profile to emerge on top.
We rate the St. Louis Cardinals at +116 as the right side at current form.
Over/Under Prediction
Last five form shows the Miami Marlins at 5.6 RPG and the St. Louis Cardinals at 4.0, giving context for the number.
These teams are combining for 9.6 runs per game recently — above the posted total of 8.0. That points toward a Over 8.0.

MLB Predictions FAQ
How does Parlamaz make St. Louis Cardinals vs Miami Marlins MLB predictions?
We use trusted data feeds and real-time odds to model each matchup. We weight the numbers that move lines—team form, matchup history, injuries, park factors, totals trends, and betting momentum—then compare our price to the market to find value. All signal, no noise. No paywalls.
What do moneyline, run line, and total mean?
Moneyline is who wins the game. Run line is a spread, usually ±1.5 runs. The total (over/under) is combined runs by both teams.
What’s a good price range for today’s pick (Aug 18, 2025)?
We list a target price in the post. If the market moves past that number, reduce stake size or pass instead of chasing worse odds.
How should I size my bets?
Use a consistent unit (about 1–2% of bankroll). Singles should be most of your volume. We like parlays — smart ones. Build them from real edges, keep legs tight (2–3), cap risk to 0.25–0.5u, and pass when the price isn’t there.
