Casey Mize gives Detroit the steadier arm, but Mason Fluharty’s pitch mix keeps this from being a simple under. At 8.5, the number is fair — the edge comes from how much you trust Fluharty to survive two trips through the order.
Mason Fluharty vs Casey Mize: Toronto Blue Jays at Detroit Tigers Betting Preview
Friday’s 3-2 grinder between the Blue Jays and Tigers stayed comfortably under the total, and Saturday’s matchup brings another game with a lower-scoring path. The difference is that this one has a more defined pitching setup: Mason Fluharty for Toronto against Casey Mize for Detroit.
Mize gives the Tigers the higher starting-pitcher floor. He enters with a 2.90 ERA over 31 innings, and that matters in a matchup where Detroit does not need dominance as much as it needs stability. If Mize gives the Tigers five or six clean innings, the under has a real foundation.
Fluharty is the more complicated side of the handicap. His 5.40 ERA through 15 innings is not enough of a sample to bury him, but it is enough to make this total uncomfortable. The pitch mix is interesting. The results are not fully there yet. That combination creates a game where the under makes sense, but only at the right price.

Why Mize Gives Detroit the Edge
This handicap starts with Mize because he is the cleaner projection. The surface numbers are strong, and the Tigers should feel comfortable leaning on him as the more reliable starter in this matchup. He has allowed only 10 earned runs across 31 innings, and his 35 strikeouts give Detroit a legitimate swing-and-miss piece against a Toronto lineup that is still trying to find consistent damage.
Mize does not need to be perfect to justify the Tigers’ favorite price. He just needs to keep Toronto from building the kind of inning that flips a total. Comerica Park helps him there. It is not an extreme pitcher’s park, but it does not reward cheap fly-ball contact the way several other American League venues do.
The key for Mize is count leverage. If he is ahead early and forcing Toronto to chase, the Blue Jays will have to string hits together rather than rely on one big swing. That is the kind of game script that supports Detroit and keeps the under live.
The Fluharty Question
Fluharty is where the bet gets tricky. His 5.40 ERA is ugly, but the arsenal is better than the number. He leans heavily on a cutter-sweeper combination, with the cutter sitting around 91 mph and the sweeper doing most of the bat-missing work.
The sweeper is the pitch that can make him dangerous. It has generated whiffs and weak contact, and when he is landing it, he can neutralize right-handed hitters long enough to get through the lineup. The problem is predictability. With limited changeup usage and not much true velocity separation, disciplined hitters can start sitting in lanes if Fluharty falls behind.
That is where Detroit’s top of the order matters. Kevin McGonigle brings a contact-oriented profile that can work counts and force Fluharty into the zone. Dillon Dingler has enough hard-contact upside to punish mistakes. Fluharty can absolutely get through this lineup once. The second trip is where the risk starts to show.
The Under Case
The under 8.5 is built on three things: Mize, Comerica Park and a Blue Jays lineup that has not consistently created separation. Friday’s 3-2 result is not predictive by itself, but it does show the kind of run environment this series can create when the ballpark keeps damage in check.
Mize gives Detroit a clear path to controlling the first half of the game. If he works efficiently, the Tigers can avoid overexposing the bullpen and force Toronto into a lower-margin offensive script. That is the cleanest under path.
There is also a reasonable case that Fluharty’s ERA is overstating how vulnerable he is. Fifteen innings is a tiny sample, and his sweeper gives him a real weapon. If he limits walks and keeps Detroit from stacking traffic, this game can sit in the 3-2 or 4-3 range deep into the afternoon.
The Red Flags
The first concern is Fluharty’s margin for error. His pitch mix is interesting, but he is not the kind of starter you blindly trust at an expensive under price. If Detroit sees the cutter early or forces him into predictable counts, the Tigers can put pressure on Toronto before the bullpen gets settled.
The second issue is the price. Under 8.5 at -120 is not bad, but it is no longer a bargain. The number already respects the run-prevention setup. Betting the under here means accepting that most of the obvious value has already been squeezed out.
There is also late-game risk. Both teams have enough bullpen volatility to turn a good handicap into a bad ticket in one inning. That is especially true if Fluharty exits early and Toronto has to cover more outs than planned.
Lean Only: Under 8.5
The lean is still under 8.5, but this is not a premium play at any price. Mize is the best reason to like the under, and Comerica Park supports the angle. The concern is that Fluharty’s profile is not clean enough to make this automatic.
At 8.5, the under is playable up to -120. If the market drops to 8, the edge is mostly gone. If the juice climbs beyond -125, it becomes a pass. The better approach is to respect the number, avoid chasing and trust the matchup only if the price stays reasonable.
Recommendation: Lean Under 8.5, playable to -120.
Projected Score: Tigers 4, Blue Jays 3
