Mets @ Blue Jays

Freddy Peralta and Patrick Corbin are enough to make an under feel annoying. That is also why this is 9 instead of a smaller number. I am still looking under, but it has to be for the right reasons.

The last game here ended 3-0

The Mets just beat Toronto 3-0 at Rogers Centre, with Nolan McLean throwing six scoreless and Brooks Raley, Luke Weaver, and Devin Williams finishing it from there. That does not mean this game copies the last one, but it does matter when the market is hanging a 9. Toronto already showed it can get stuck in this series, and New York did not need a big scoring night to get out with a win.

Peralta gives the under a cleaner starting point than the ERA says

Freddy Peralta’s full line is not spotless, with a 4.53 ERA over 91.1 innings, 35 walks, and 12 homers allowed. The part I care about is that he still has 88 strikeouts in that workload, so he is not just hoping balls find gloves. His last start was a step back toward useful, with 5.2 innings, five hits, five strikeouts, one walk, and three runs allowed, none earned.

Corbin is the uncomfortable piece, and that is already in the number

Patrick Corbin is the reason this under is not clean. His season line sits at a 5.09 ERA over 69.0 innings, and his June was rough, with an 8.69 ERA and 5.95 FIP across five starts and 19.2 innings. I am not betting this because Corbin suddenly has to look sharp. At 9, I need him to survive enough of the early game without turning every baserunner into damage.

The Mets still have to cash their chances

The Mets’ offense entered this Toronto series described as underperforming and struggling with runners in scoring position. That is the part that keeps me from overreacting to Corbin’s ugly month. A bad starter can put runners on, but the over still needs those innings finished with real damage. If New York keeps wasting chances the way it has been described entering this set, 9 becomes a much bigger ask.

Toronto’s name is louder than its current offense

The Blue Jays came into the series underachieving after a 2025 World Series appearance, with the offense and starting rotation both described as having regressed. That lines up with what happened in the opener, when Toronto was shut out at home. I am not treating the Jays like a run engine here just because the setting and the names make the over tempting.

The bullpen angle is not all bad for an under

Toronto’s bullpen was still described as a strength, even with the offense and rotation lagging. That matters if Corbin gives the Jays a few imperfect but usable innings and the game gets handed off before it gets loose. I do not need a clean pitching duel for this number. I need enough resistance in the middle innings to keep one bad frame from turning into a full total chase.

Rogers Centre lowers one kind of chaos

Rogers Centre has a retractable roof, which cuts down the open-air weather uncertainty that can make totals harder to trust in fixed outdoor parks. I am not building the whole bet on the building, and I am not claiming the park does the work by itself. It just removes one variable I do not want fighting an under when the handicap is already tied to shaky starters and inconsistent offense.

The obvious way this loses is Corbin

The counter is simple. Corbin’s June was bad enough that he can break this bet before the under ever gets comfortable, and Peralta’s walks and homers allowed leave some risk on the other side too. If either starter gives away free traffic and the next hitter cashes it, 9 can shrink fast. That is the price of playing an under with two flawed arms instead of two aces.

Why I am still taking Under 9

This is not a blind trust-the-pitchers play. It is a bet that 9 is enough room when the Mets have been struggling to finish scoring chances, Toronto’s offense has not matched its reputation, Peralta still brings strikeout ability, and the prior game in this park landed at 3-0. Corbin keeps it from being pretty, but the number gives me enough cushion to live with some mess. Under 9, -120.
