Phillies vs. Marlins Prediction: Wheeler Rolls Into Miami’s 10-Game Freefall
Zack Wheeler and the Phillies visit a reeling Marlins team that's lost 10 straight. Full odds, analysis, and our best bet for Monday night at loanDepot park.
The Phillies own this matchup on paper, but the Marlins have Zack Wheeler working against them and a bullpen that’s been leaking runs for two weeks straight.
Quick take:
- Pick: Phillies moneyline
- Why: Wheeler’s dominant season meets a Marlins offense mired in an 0-10 slide
- The number to watch: Miami is batting .213 over its last 10 games
Philadelphia rolls into loanDepot park at 57-49, sitting second in the NL East and clinging to a wild-card cushion, while Miami has slipped to 52-54 and 10.5 games back in the division. The Phillies have owned this season series too, taking five of the first seven meetings between these two clubs, and they’ll lean on their ace to make it six.
Zack Wheeler gets the ball for Philadelphia, and he’s been about as good as any starter in baseball this year. Tyler Phillips draws the assignment for Miami, and the gap between these two arms is the whole story of Monday night.
Why Vegas Isn’t Buying a Miami Upset (Yet)
The Phillies opened as solid road favorites, with moneyline prices ranging from -164 to -181 depending on the book and the spread sitting at Philadelphia -1.5. FanDuel has the total at 7.5 runs, with the under getting slightly more respect than the over. That number makes sense given loanDepot park’s reputation as a pitcher’s venue, but Miami’s bullpen issues have made even modest totals playable from the over side lately.
Wheeler’s Dominance Runs Into a Marlins Team in Freefall
Wheeler enters at 10-2 with a 2.16 ERA, a 0.88 WHIP, and 117 strikeouts across 100 innings — numbers that put him firmly in the NL Cy Young conversation. He’s started nine games this season with Philadelphia as the moneyline favorite and won every single one of them. Tyler Phillips, by contrast, is 2-5 with a 3.52 ERA and a 1.39 WHIP, and Miami is 5-5 against the spread in his starts with a set line.
The bigger issue for the Marlins isn’t just who’s on the mound — it’s how the lineup has completely stalled. Miami has lost 10 straight games, hitting a miserable .213 as a team with a 4.85 ERA and getting outscored by 25 runs in that stretch. Philadelphia hasn’t been world-beaters either at 4-6 over its last 10, but the Phillies have still outscored opponents by four runs in that span, a sign the offense is at least competitive even during a rough patch.

Miami is hitting .213 with a 4.85 ERA and has been outscored by 25 runs across its current 10-game losing streak.
That kind of collapse doesn’t turn around against a pitcher like Wheeler. Kyle Stowers has been one of the lone bright spots in the Miami lineup since returning from injury, but even a hot individual bat has struggled to generate much traction behind him. Bryce Harper and the Phillies’ middle of the order, meanwhile, have been productive enough to make Wheeler’s starts feel almost automatic — Philadelphia is 9-5 against the spread in his outings this year.
Injuries have also thinned out Miami’s pitching depth. The Marlins have placed multiple relievers on the injured list in July, including William Kempner (elbow sprain) and Anthony Bender (shin stress reaction), forcing manager Clayton McCullough to lean on a bullpen that’s already been shredded during the losing streak. That matters in a game where the total sits at 7.5 — if Wheeler cruises into the sixth or seventh, Miami’s relief corps could be tasked with covering a lot of innings against a lineup that’s shown it can pile on. Bettors tracking value on this side should check the FanDuel promo code before locking in a number, since lines have moved slightly since opening.
Prediction and Best Bet
Wheeler’s track record as a favorite, combined with Miami’s complete offensive collapse, makes this one of the more comfortable spots on the board for Philadelphia. The Marlins have shown flashes with Stowers and Otto Lopez, but a 10-game losing streak isn’t the platform to spring an upset against a pitcher who hasn’t lost when backed as the favorite all season.
| Tue, Sep 15 • 6:45 PM | Spread | Money | Total |
| Philadelphia Phillies |  -2 (-105) |  -215 | O 8.5 (106) |
| Washington Nationals | +2 (-118) |  +180 |  U 8 (-106) |
The pick:
- Prediction: Phillies 6, Marlins 2
- Best Bet: Phillies on the moneyline
Wheeler against a lineup this cold is about as close to a sure thing as this sport offers, and the Phillies should be able to close out this series opener comfortably.
