The Cardinals and Reds open a five-games-in-four-days stretch on Monday with a day/night doubleheader at Great American Ball Park, and Game 1 comes with a genuine storyline: rookie call-up Quinn Mathews gets the ball for St. Louis (63-61) against Cincinnati (59-64) as the Cardinals try to keep pace in a tight NL Central race.

Reds vs Cardinals Odds: Novig Money Line Contracts
Novig runs as a peer-to-peer exchange, so every contract is quoted as a straight implied probability rather than cents on the dollar. Buy the side you think is undervalued and your contract pays out if that team wins; the price moves in real time as traders take the other side.
St. Louis Cardinals (trading at 52% implied probability)
St. Louis is a narrow favorite on the moneyline board despite the sub-.500 stretch that's dragged their record down. The Cardinals lean on a top-heavy lineup led by Jordan Walker, who's been the hottest bat in the organization over the past month.
Cincinnati Reds (trading at 49% implied probability)
Cincinnati sits just behind at 49% even with home-field advantage, a reflection of how thin their rotation is in this doubleheader opener and how inconsistent the offense has looked lately against left-handed arms like Mathews.

Reds vs Cardinals Spread and Total Predictions
- Cardinals -1.5 (42.0%): Traders aren't buying St. Louis to cover as a small favorite, which tracks with a rookie starter making his second career MLB appearance on the mound.
- Reds +1.5 (60.0%): The Reds getting the extra run and a half is the more popular side of the spread board right now, priced as a clear favorite to cover at home.
- Over 9.5 runs (48.5%): A near coin-flip price, with the board also offering Over 8.5 (59.0%) and Over 10.5 (42.0%) for traders who want a different number.
- Under 9.5 runs (52.5%): The slight favorite on the total, with Under 8.5 (43.0%) and Under 10.5 (60.0%) also live if you want to shop the line.
Home Runs: Reds vs Cardinals Player Props
Some home run contracts on this board only have the Over side actively priced, so a few entries below show a single figure rather than a full Over/Under pair.
- Alec Burleson (Over 0.5 HR: 24.0%, Under 0.5: 78.5%): Burleson is St. Louis's most consistent power source in the middle of the order, and the price reflects a hitter who runs into a homer more often than most on this board.
- Jordan Walker (Over 0.5 HR: 19.5%, Under 0.5: 84.5%): Walker's power hasn't fully shown up in August the way his contact rate has, which is why this price sits lower than his overall hot streak might suggest.
- Elly De La Cruz (Over 0.5 HR: 19.0%, Under 0.5: 83.5%): De La Cruz remains the most explosive bat on either roster, and this is one of the shorter Over prices on the board relative to raw power upside.
- JJ Bleday (Over 0.5 HR: 20.0%): Bleday's price sits near the top of the Reds' home run board, consistent with a lefty bat who's found some pull-side pop lately.
- Eugenio Suarez (Over 0.5 HR: 19.5%): Suarez remains a threat to run into one against a rookie arm still working out his fastball command at the big-league level.
- Sal Stewart (Over 0.5 HR: 16.0%, Under 0.5: 84.5%): Stewart went deep against the White Sox last week, and traders have priced in a bit of that carryover momentum here.
- Ivan Herrera (Over 0.5 HR: 16.0%, Under 0.5: 88.0%) and JJ Wetherholt (Over 0.5 HR: 16.0%, Under 0.5: 87.0%): both sit near the bottom of the Cardinals' power tier, priced as depth bats rather than primary threats.
- Tyler Stephenson (Over 0.5 HR: 16.0%): Stephenson's price reflects a catcher who provides occasional pop but isn't the first read in this Reds lineup.
Hits and Total Bases: Reds vs Cardinals Player Props
Most hit contracts on this board list only the Over side, so the entries below show that figure unless an Under price is also live.
Hits
- Alec Burleson (Over 1.5 Hits: 38.5%): A multi-hit price for Burleson reflects his high-contact profile against a Reds pitching staff that's leaned on younger arms in recent weeks.
- Sal Stewart (Over 0.5 Hits: 74.0%) and Jordan Walker (Over 0.5 Hits: 74.0%): both sit at the top of the single-hit market, the kind of price you'd expect from hitters running hot at the plate right now.
- JJ Wetherholt (Over 0.5 Hits: 72.0%), Masyn Winn (Over 0.5 Hits: 69.5%), Joshua Baez (Over 0.5 Hits: 68.5%), JJ Bleday (Over 0.5 Hits: 67.5%), Nathan Church (Over 0.5 Hits: 67.0%), Tyler Stephenson (Over 0.5 Hits: 66.5%), Dane Myers (Over 0.5 Hits: 65.0%), Jose Fermin (Over 0.5 Hits: 65.0%) and Noelvi Marte (Over 0.5 Hits: 64.5%): round out a crowded single-hit board where most everyday starters clear 60% to reach base at least once.
Total Bases
- Alec Burleson (Over 1.5 Total Bases: 53.0%): Burleson's extra-base pop puts him just above a coin flip to clear a single and a half, the top price on this leaderboard.
- Elly De La Cruz (Over 1.5: 48.0%) and Sal Stewart (Over 1.5: 48.0%): both sit right around even money, reflecting hitters capable of an extra-base knock but not locks to get one.
- Jordan Walker (Over 1.5: 47.5%, Under 1.5: 55.5%): one of the few contracts here with both sides actively priced, with the market leaning slightly toward the under given how many of Walker's recent hits have been singles.
- Ivan Herrera (Over 1.5: 45.5%), JJ Bleday (Over 1.5: 45.0%), JJ Wetherholt (Over 1.5: 44.5%), Joshua Baez (Over 1.5: 42.0%) and Masyn Winn (Over 1.5: 39.5%): fill out the rest of the board on the lower end of the total bases spectrum.
Hits, Runs and RBIs: Reds vs Cardinals Player Props
- Ivan Herrera (Over 1.5: 60.0%): the top price on this combined market, with Herrera getting regular at-bats in the middle of the St. Louis order against a Reds staff still finding its footing.
- Elly De La Cruz (Over 1.5: 59.0%, Under 1.5: 46.5%) and Sal Stewart (Over 1.5: 59.0%, Under 1.5: 48.5%): two of the more actively traded contracts on the board, both with real two-way liquidity.
- JJ Wetherholt (Over 1.5: 57.5%, Under 1.5: 49.0%) and Jordan Walker (Over 1.5: 57.5%, Under 1.5: 49.0%): nearly identical pricing for two of St. Louis's most productive recent bats.
- Alec Burleson (Over 2.5: 47.5%, Under 2.5: 58.5%): a tougher number to clear given the higher threshold, and the market has this leaning toward the under.
- Joshua Baez (Over 1.5: 53.0%, Under 1.5: 55.0%), JJ Bleday (Over 1.5: 52.5%, Under 1.5: 57.0%), Masyn Winn (Over 1.5: 51.0%, Under 1.5: 57.0%), Tyler Stephenson (Over 1.5: 51.0%) and Nathan Church (Over 1.5: 49.5%, Under 1.5: 58.0%): round out a tightly bunched combined-production market.
Quinn Mathews Pitcher Props
Mathews is the only pitcher with an active board here since he's a confirmed starter, while Cincinnati's Game 1 arm was still unresolved at publish time.
- Strikeouts Thrown (Over 4.5: 49.5%, Under 4.5: 56.0%): the market leans toward the under, a reasonable read on a pitcher with a tiny MLB sample and a Triple-A profile built more on efficiency than swing-and-miss stuff.
- Outs Recorded (Over 13.5: 57.0%, Under 13.5: 44.0%): traders are pricing Mathews to work at least 4.5 innings, though a rookie making just his second big-league start in a doubleheader opener carries real hook risk.
- Earned Runs Allowed (Over 2.5: 48.5%): a near coin-flip price that reflects the uncertainty around facing an MLB lineup for only the second time.
- Walks Allowed (Under 1.5: 33.5%): the only actively priced side, and a relatively long price suggesting the market expects some rookie command issues.
Best MLB Player Props Today for Reds vs Cardinals
Pulling from the boards above, a few contracts stand out as good value on Novig for this doubleheader opener.
- Jordan Walker Over 0.5 Hits (74.0%): Walker is hitting .313 in August with nine RBI, one of the hottest stretches on either roster right now. A price this high for a single hit against a Reds staff leaning on unproven arms is a strong floor play rather than a longshot swing.
- Sal Stewart Over 0.5 Home Run (16.0%): Stewart went deep against the White Sox last week, and this price gives real plus-money value for traders who think that power carries over into a series against a rookie starter still working out his fastball command in the majors.
- Quinn Mathews Under 13.5 Outs Recorded (44.0%): the market has Mathews going 4.5-plus innings as the slight favorite, but a second career MLB start, in a day/night doubleheader opener where managers tend to play it safe with pitch counts, is exactly the setup where a shorter-than-expected outing is live. This one's a bet on the hook coming quicker than the board expects.
Each of these ties a specific price back to something concrete happening on the field this week, which is the difference between chasing a longshot and buying a contract you actually have a read on.
Reds vs Cardinals Price Analysis: What's Moving the Market
The moneyline at 52/49, despite St. Louis's better overall record, shows how much weight traders are putting on the pitching matchup rather than season-long form. Mathews making his second career start, with a small but strong Triple-A track record, is the biggest driver of uncertainty on this board.
The spread and total markets tell a similar story. Cincinnati covering as the favorite at +1.5 (60.0%) suggests the market doesn't fully trust the Cardinals to blow this one open even as a moneyline favorite, while the total sitting just above a coin flip reflects two lineups that have each had stretches of feast and famine over the past month.
On the player props side, the home run board is unusually top-heavy, with no single hitter clearing 25%, suggesting neither lineup has a true standout power threat trending hot into this series.
