The Boston Red Sox head into Comerica Park on Wednesday looking for a sweep over the Detroit Tigers, and the pitching matchup between Sonny Gray and Jack Flaherty creates one of the more lopsided spots on the slate despite the moneyline staying close to a coin flip. For more MLB picks and daily breakdowns, our coverage runs deep, but this Red Sox vs Tigers finale deserves a focused handicap given Flaherty’s collapsing Statcast profile, Gray’s historical dominance over the Tigers’ current roster and a market that has not fully priced in either factor.
Quick Picks and Prediction
- Moneyline Pick: Red Sox -105
- Total Pick: Under 8.5
- Projected Final Score: Red Sox 5, Tigers 2
Odds and Line Movement
The market opened with Detroit as a slight home favorite at -122 and has steadily flipped over to Boston as game day approached, with the Red Sox now sitting at -105. The total has climbed from 8 at open to 8.5, with extreme public Over support across every recorded window, suggesting the recent move has been driven by sharper money buying back on the Red Sox side and on the Under at the new number.

Red Sox vs Tigers Key Matchups and Handicap
The handicap on this game starts with the Jack Flaherty problem. Through his first seven starts, Flaherty is sitting at a 5.90 ERA with a 1.79 WHIP, and the underlying numbers are even more concerning than the surface line. His hard-hit rate has climbed from 35.9 percent in 2024 to 43.8 percent last year to 46.3 percent this year, his walk rate has jumped from 5.9 percent to 8.7 percent to a jaw-dropping 17.7 percent so far this season, and his strikeout rate has dropped from 29.9 percent to 27.6 percent to just 22.7 percent. He enters Wednesday in the bottom-25th percentile among pitchers in expected ERA, average exit velocity, chase rate, walk rate, hard-hit rate and ground ball rate.
The recent results match the underlying numbers. Flaherty has not made it through the fourth inning in any of his last three starts, and during that span he has allowed 12 runs on 13 hits with 11 walks and four home runs in just 9.0 innings. With Tarik Skubal battling an elbow injury, the Tigers need Flaherty to find something that works, but the trend is firmly going the other way. That kind of profile against a healthy, motivated Red Sox lineup is the cleanest reason to stay on the favored side of this game.
Sonny Gray brings the opposite trajectory into this start. He is making his first start since a brief IL stint, with his last outing coming against the Tigers three weeks ago when he left early for precautionary reasons due to a hamstring issue. Gray threw a lengthy bullpen session a few days ago with no issue and is expected to be at full strength. The matchup history with the current Detroit roster is brutal: the Tigers’ current group is hitting .197 in 64 plate appearances against Gray with a 37.5 percent strikeout rate and a .222 weighted on-base average. Even if Gray runs into trouble, Boston’s bullpen should be in good shape behind him after Brayan Bello went 7.0 innings on Tuesday to give most of the relievers the night off. The result is a clean lean to the Red Sox moneyline and a corresponding lean to Under 8.5.
BOS and DET Betting Trends
Boston comes into this finale having won the first two games of the series and now has a chance to complete the sweep with their best matchup of the three on the mound. Bello’s seven-inning outing on Tuesday set up the bullpen perfectly, and the public has caught up to the situation, with 77 percent of the moneyline money sitting on the Red Sox in the most recent refresh. The ticket count is still split at 50 percent, which suggests the move from +102 to -105 has been driven by sharper money rather than recreational tickets.
Detroit is in a tough spot with Skubal’s elbow issue lurking in the background and Flaherty showing the worst Statcast profile of his career. Even at home, the Tigers are walking into a matchup where their starter has not made it through the fourth inning in three straight outings and their lineup has historically been overmatched against the opposing starter. The total has drawn extreme public Over support, with 100 percent of both money and tickets on the Over across multiple windows, but Gray’s history against this lineup and Flaherty’s likely early hook into a rested Boston bullpen point the other way.
BOS and DET Key Injuries and Notes
Boston’s most relevant note is the bullpen rest situation. Bello’s seven-inning outing on Tuesday means the late-inning arms are fresh, which is critical in any one-run scenario and especially valuable behind a starter making his first appearance off the IL. Gray himself reported no issues in his bullpen session, and he is expected to be at full strength, removing the main concern about his early hook last time out.
Detroit’s biggest issue is what is happening to Flaherty in real time and the cloud over Skubal’s availability. With Skubal battling an elbow injury, the Tigers do not have the safety net of their ace if this start goes sideways, which is exactly the kind of situation that turns a struggling starter’s outing into a cascade. The bullpen is fully exposed if Flaherty cannot get through four innings again, and that is the most likely path to a multi-run Boston win.
Red Sox vs Tigers Moneyline and Total Picks
- Moneyline Pick: Red Sox -105
- Total Pick: Under 8.5
Red Sox moneyline is the cleanest play on the board given Flaherty’s collapse, Gray’s historical dominance over the Tigers’ current roster and Boston’s rested bullpen behind their starter. Even in this kind of pitching mismatch, the price has only inched up to -105, which keeps the moneyline as the most efficient way to capture the edge. Under 8.5 lines up with Gray’s ability to neutralize this Detroit lineup and the likelihood that the Red Sox put runs up early without needing a high-scoring shootout to win the game.
Final Score Prediction
- Final Score: Boston 5, Detroit 2
Gray works five-plus innings with the kind of ground ball and strikeout mix that has carved up this Detroit lineup before, Flaherty exits early after another walk-heavy outing and the Red Sox break the game open in the middle innings before a rested bullpen closes things out. A 5-2 final lands the Red Sox moneyline and clears the Under 8.5 by a run and a half.
How to Bet Red Sox vs Tigers
With Boston now sitting at -105 on the moneyline after opening as a road dog at +102, the timing of the price matters. Line shopping across multiple books for the best Red Sox moneyline number can pick up an extra few cents and meaningfully change the long-term math on a play like this. The total at 8.5 has bounced between -108 and -115 on the Under, so the same line-shopping logic applies on Under 8.5.
