The Marlins and Phillies are back at it Tuesday night at Citizens Bank Park after Miami dropped a narrow 6-5 decision in the series opener, and the Polymarket board already has Philadelphia priced as the clear favorite behind Zack Wheeler.
Before diving into the moneyline, spread, and the best home run props today for this Marlins vs Phillies matchup, lock in the current Polymarket promo code: ACTION.
Marlins vs Phillies Odds: Polymarket Money Line Contracts
Polymarket's moneyline works like any other event contract: you're buying Yes or No shares on which team wins, and the cents price doubles as the market's implied probability. Shares settle at $1 if your side wins and $0 if it loses, so the price you pay today is effectively your entry cost into that outcome.
Miami Marlins (34%, Yes 34¢ / No 67¢)
Miami is trading as the live underdog, and for good reason: they're turning to a rotation piece with far less margin for error than Philadelphia's ace, even with the offense showing signs of life after averaging solid contact over its last several games.
Philadelphia Phillies (67%, Yes 67¢ / No 34¢)
Philadelphia sits comfortably above two-thirds implied probability with Wheeler on the mound, though his last three starts have been shakier than his 10-4, 2.89 ERA season line suggests, which is part of why Miami's price hasn't collapsed further.

Marlins vs Phillies Spread and Total Predictions
The spread and total round out the core board for this Marlins vs Phillies matchup, and both are priced tight enough to suggest the book expects a competitive, moderate-scoring game rather than a blowout.
Marlins +1.5 (53¢) / Phillies -1.5 (48¢)
Miami buying the run and a half at 53¢ is a slightly cheaper way to fade the favorite than the straight moneyline, especially with Wheeler's recent walk rate trending up against left-handed-heavy lineups like Miami's.
Over 8.5 (48¢) / Under 8.5 (53¢)
The under carries a small edge in price, but both offenses have been hitting the ball hard lately, and 11 combined runs crossed the plate in this series just one night ago, so the total could easily push higher than the board suggests.
Marlins vs Phillies Best Home Run Props Today
This is where the Polymarket board gets interesting. Ranked from the highest price down to the lowest, here's every home run contract Polymarket has live for tonight's Marlins vs Phillies best home run props today, with Kyle Schwarber sitting at the top of the board by a wide margin.
Note that several of these contracts only show an active Yes price right now, with the No side listed as a dash on the board. That's normal for lower-liquidity prop markets and doesn't affect how the Yes contract itself trades.
- Kyle Schwarber (Home Run Yes: 25¢): Schwarber is the clear headliner among tonight's best home run props, and the price reflects it. He's tied atop the MLB leaderboard with 37 home runs this season, and he's been on an absolute tear lately, going 11-for-30 with nine RBI over his last eight games and hitting multiple homers in his last outing at the Field of Dreams game. Facing a Wheeler-led staff that's allowed a noticeably higher barrel rate to lefties recently, 25¢ is a fair reflection of how live Schwarber is right now.
- Bryce Harper (Home Run Yes: 17¢): Harper sits comfortably in second on this board, which tracks with Philadelphia's lineup depth behind Schwarber. He doesn't need a specific platoon edge to be a threat, and Miami's pitching staff has had bouts of hittability against the middle of the Phillies' order this season.
- Griffin Conine (Home Run Yes: 15¢) / Heriberto Hernández (Home Run Yes: 15¢): These two are tied for the third-highest price on the slate, and Conine's inclusion here is notable. He's been destroying baseballs over his last ten games with a slugging percentage well above his season average, and he draws a Wheeler who has allowed harder contact and a higher home run rate to left-handed hitters over his last several outings.
- Owen Caissie (Home Run Yes: 13¢): A lower-probability swing, but Caissie has carried some pop in Miami's lineup as the offense has heated up as a whole over its last several games.
- J.T. Realmuto (Home Run Yes: 12¢): Realmuto rounds out the middle tier for Philadelphia. He's not typically the first name associated with the Phillies' power surge, but he's capable of popping a homer against a Miami staff that's been generous with the long ball this month.
- Trea Turner (Home Run Yes: 11¢): Turner's game leans more toward contact and speed than raw power, which is reflected in a price well behind Harper and Schwarber, even in a favorable home run environment for Philadelphia's lineup as a whole.
- Alec Bohm (Home Run Yes: 9.8¢ / No: 99.9¢): Bohm is one of the few contracts here with an actively priced No side, and 9.8¢ reflects his more ground-ball-oriented approach relative to the top of Philadelphia's order.
- Otto Lopez (Home Run Yes: 9¢): A modest price for a Miami bat that's more of a table-setter than a power threat, even with the Marlins' offense trending up lately.
- Xavier Edwards (Home Run Yes: 7.1¢ / No: 99.9¢) and Luis Arraez (Home Run Yes: 7.0¢ / No: 99.9¢): These two sit at the bottom of tonight's board, and it fits their profiles. Both are contact-first hitters with limited home run track records, so their prices are more about covering the field than reflecting real power upside.
Zack Wheeler Strikeouts: Marlins vs Phillies Prop
Alongside the home run market, Polymarket also has a strikeout prop live on Wheeler himself.
- Zack Wheeler (Over 6.5 Strikeouts: 62¢, Under 6.5: 99¢): Wheeler's punchout numbers have held up better than his ERA lately, and a lineup with several strikeout-prone bats gives him a reasonable path to clearing 6.5, even in a start where his overall command has wavered.
Marlins vs Phillies Price Analysis: What's Moving the Market
The biggest signal on this board is how far Schwarber has separated himself from the rest of the home run field. At 25¢, he's priced eight cents above Harper and ten cents above the next tier, which lines up with his current form: he's tied for the MLB home run lead and has been running hot for more than a week now.
The other notable shift is on the Marlins side of the ledger. Conine's 15¢ price is high for a bottom-of-the-order bat, but his recent power surge and a favorable platoon matchup against Wheeler explain why the market has bid him up alongside Hernández rather than leaving him priced like a typical seventh or eighth hitter.
