Red Sox at Marlins Predictions, Odds and Betting Picks
Jesse M. Cox Published 25/08/2026
The Boston Red Sox are -124 road favorites against the Miami Marlins at DraftKings, with the run line set at Boston -1.5 (+134). Payton Tolle brings an 8-6 record, 3.08 ERA and 134 strikeouts into the matchup, giving Boston the clearest starting-pitching edge while Miami enters with its starter still TBD.
The total is only 7.0 runs, which puts a premium on Tolle's efficiency and the Marlins' eventual pitching announcement. Miami's Pete Fairbanks also left Monday's game with throwing-arm numbness, creating another late-inning concern for a team already dealing with multiple bullpen injuries.
Red Sox vs Marlins Game Preview
Boston enters Tuesday with a 72-59 record and a four-game winning streak after taking the series opener 4-2 in Miami. The Red Sox also won their previous three games against San Francisco, scoring 5, 3 and 6 runs, while their season road record stands at 38-27.

Tolle is scheduled to make his 22nd start of the season after posting a 3.08 ERA, 1.08 WHIP and 134 strikeouts over 120 innings. His most recent outing against Arizona lasted five innings with three runs allowed and six strikeouts, but he had posted a 1.78 ERA over his previous four starts. Miami has not announced its Tuesday starter, leaving a major lineup-versus-pitcher variable unresolved.
Miami is 67-65 and 41-25 at home. Kyle Stowers is back from the IL, while Fairbanks' arm issue adds uncertainty to the Marlins' bullpen.
Moneyline Pick
Red Sox ML is the pick. Tolle's 3.08 ERA and 134 strikeouts give Boston a strong advantage while Miami has yet to name its starter. The Red Sox also enter with four straight wins and a 38-27 road record, making the -124 DraftKings price playable.
Miami's 41-25 home record keeps this from being a heavy position, but Boston has won 19 of its last 20 games against teams with records of .500 or better. The Marlins also lost their closer Fairbanks to an arm issue Monday, which weakens the late-game picture if Tuesday again comes down to the final innings.
Pick: Red Sox ML (-124 at DraftKings).
Run Line Pick
The Red Sox -1.5 is the run line pick. The +134 DraftKings price gives a better payout than the moneyline, and Boston's pitching edge becomes more useful if Miami enters the game with a replacement-level or short-rest pitching plan. Tolle has a 3.08 ERA across 120 innings, while Miami's starter remains TBD. The risk is Miami's 41-25 home record, so the run line is more aggressive than the moneyline. The +134 price compensates for that added margin requirement.
Pick: Red Sox -1.5 (+134 at DraftKings).
Best Player Prop
- Payton Tolle strikeouts Over 5.5 (TBD at DraftKings). Tolle has 134 strikeouts in 120 innings, averaging 1.12 strikeouts per inning, and he recorded six strikeouts in his most recent start. He also posted six or more strikeouts in his latest outing despite completing only five innings.

Game Total Pick
Under 7.0 runs is the pick. Tolle brings a 3.08 ERA and 1.08 WHIP into the game, and the total is already priced at a low 7.0 runs at DraftKings. The retractable roof at loanDepot park also removes Miami's late-August heat and humidity from the actual playing conditions, keeping the game environment controlled.
The biggest reason to avoid the Over is the uncertainty around Miami's starter. Boston scored four runs Monday, but three of those runs came after Fairbanks left in the ninth, while Sandy Alcantara allowed only one run across seven innings. That 4-2 result shows how quickly the game can remain under a seven-run number when the starting pitchers control the first six or seven innings.
Pick: Under 7.0 (-105 at DraftKings).
Best Trades for Red Sox vs Marlins
Prediction markets give this matchup a tighter probability range than the DraftKings moneyline. Polymarket currently prices Boston near 57% and Miami near 43%, while the first-inning run market is close to a coin flip.
- Red Sox vs. Marlins game winner: YES on Red Sox at 59¢ on Polymarket. Boston has a 38-27 road record and enters with four straight wins, while Tolle owns a 3.08 ERA and 134 strikeouts. The 59¢ price is close to the sportsbook's -124 moneyline, which implies about a 55.4% break-even probability before removing the vig.
- Red Sox vs. Marlins game winner: NO on Marlins at 42¢ on Polymarket. Miami's 41-25 home record is a strong counterpoint, but the unresolved starting-pitcher situation leaves the Marlins with more uncertainty. Boston's 57% Polymarket price and -124 DraftKings line both place the Red Sox ahead of Miami in the market.
- Run in the first inning: NO at 54¢ on Polymarket. The market is nearly split at YES 49¢ and NO 54¢, while Tolle enters with a 3.08 ERA and Miami has not announced its starter. The seven-run game total also points toward a lower-scoring early-game setup.

Final Takeaways
The Red Sox has the stronger starting-pitching setup with Tolle carrying a 3.08 ERA and 134 strikeouts into Tuesday's game. The Red Sox ML is the safest of the two side plays, while the +134 run line offers more return for bettors willing to accept the extra margin requirement. The Under 7.0 also fits the pitching profile, but Miami's starter must be confirmed before the game for the strongest read on the total.
