Toronto is the 51.5c favorite in the series finale at Rogers Centre (52c on Kalshi, 51c on Polymarket), and that price sits on top of a 52-59 record and a Max Scherzer start carrying a 9.49 ERA. St. Louis, 54-57 overall and 26-25 on the road, trades at 49c on Kalshi, the only book quoting the Cardinals side. Toronto has taken the first two games 3-1 and 5-1 while holding St. Louis to two runs, and that is the read the market is pricing into a near coin flip. First pitch is 1:37 pm ET on Sunday, August 2, 2026.
The Cardinals vs Blue Jays finale is the tightest game on the Sunday board: Toronto 51.5c, St. Louis 49c, a 2.5c gap between two teams a combined 14 games under .500. Toronto (52-59) is last in the AL East, 13.5 games behind Tampa Bay (65-45). St. Louis (54-57) is fourth in the NL Central, 15 games behind Milwaukee (68-41). Neither club is playing for standings position, and the market reflects that: the liquidity is concentrated in the moneyline and the match total, not in anything with a season attached.
Cardinals vs Blue Jays Market Context
Toronto trades at 52c on Kalshi and 51c on Polymarket for an average of 51.5c. The Cardinals side is 49c and trades on Kalshi only. Polymarket has not listed a St. Louis moneyline contract for this game, so 49c is a single-book quote with no cross-platform check behind it. The Kalshi pair sums to 101c, which is 1c of vig and the tightest two-sided pricing on this board. A trader who wants Toronto can pay 51c on Polymarket instead of 52c on Kalshi; a trader who wants St. Louis has one venue.
The moneyline has not moved. Toronto printed 52c at every Kalshi snapshot from 8:21 pm ET Saturday through 10:20 pm ET, and the Cardinals contract held 49c across the same four snapshots. This is a market that has already absorbed the announced starters and the first two games of the series and sees no reason to reprice. Volume supports the read: the Cardinals contract carries $3.1K in lifetime Kalshi volume against $2.7K on the Blue Jays contract, and those two lines hold essentially all of the real money on this game.
Toronto has won four of its last five, including 3-1 on July 31 and 5-1 in Saturday's game, and leads the series 2-0 going into the finale. St. Louis has lost four of five and has scored two runs across the two games at Rogers Centre. The 51.5c on Toronto is that form plus home field, and very little else.
Cardinals vs Blue Jays Pitching Matchup: Scherzer vs McGreevy
Max Scherzer (1-4, 9.49 ERA, 1.82 WHIP) starts for Toronto. He has thrown 24.2 innings this season with 18 strikeouts, 14 walks, 31 hits, and nine home runs allowed. The home run rate is the number that matters: nine in under 25 innings, in a park that plays fair to left and short to right. Dylan Cease (2.41 ERA, 174 strikeouts) leads the Toronto staff but is not the listed probable, so the Blue Jays are asking a bullpen to cover whatever Scherzer does not.
Michael McGreevy (4-9, 3.57 ERA, 1.20 WHIP) goes for St. Louis with 116 innings, 76 strikeouts, and 29 walks. He leads the Cardinals staff in ERA, and his 4-9 record is a run-support artifact rather than a performance signal. On starting pitching alone this is a Cardinals game, and ESPN's matchup model agrees, putting St. Louis at 60.3% against a 49c market price. That 11-point gap between model and market is the single largest disagreement on this game.
The counterweight is the lineups. Toronto has Kazuma Okamoto (24 home runs, 69 RBI) and Ernie Clement (.292) against a Cardinals offense that has produced two runs in 18 innings in this series. Jordan Walker (22 home runs, 79 RBI) and Alec Burleson (.284) lead St. Louis, and both went quiet in the first two games. One caution on the props: Kalshi's Cardinals strikeout ladder is posted under Matthew Liberatore, not McGreevy, so confirm the pitcher before trading that side. Scherzer's ladder is named correctly and prices over 2.5 strikeouts at 80c on Kalshi against 61c on Polymarket. That 19c split is the widest cross-platform gap on the board, but with $1 of Kalshi volume and none on Polymarket it is quote noise, not an edge.
Cardinals vs Blue Jays Run Line and Total
The match total sits at 8.5 runs with the over at 55.5c (55c Kalshi, 56c Polymarket). Over 9.5 trades at 45.5c and over 7.5 at 63c on Kalshi. That is a market pricing a mid single digit run environment at Rogers Centre despite Scherzer's home run rate, and the 8.5 line is the second deepest pool on the board with $1.0K of Kalshi volume.
The run lines are close to symmetric. Toronto -1.5 trades at 35c (34c Kalshi, 36c Polymarket) and St. Louis -1.5 at 37.5c (37c Kalshi, 38c Polymarket). The market prices the Cardinals as slightly more likely to win by multiple runs even though they are the moneyline underdog, which is consistent with the pitching read: the side with the better starter carries the wider blowout distribution. Team totals put Toronto over 1.5 runs at 82c and St. Louis over 1.5 at 77c.
The first five innings board is the cleanest expression of the starter mismatch, because it isolates Scherzer and McGreevy from the bullpens. Over 4.5 runs through five trades at 57c, over 3.5 at 69.5c, and the first five run line has St. Louis -1.5 at 33c against Toronto -1.5 at 31.5c. A run in the first inning prices at 52c (51c Kalshi, 53c Polymarket).
When the Cardinals vs Blue Jays Market Resolves
The market resolves on Sunday, August 2, 2026, when the game at Rogers Centre goes final. First pitch is 1:37 pm ET. The moneyline pays the winner, the run line and match total settle on the official final score, and the first five innings contracts settle on the score after the fifth. Both platforms settle from the official MLB result.
Key Cardinals vs Blue Jays Catalysts
Scherzer's first two innings: a 9.49 ERA and nine home runs in 24.2 innings mean the Toronto 52c is one swing from repricing to the low 30s in-game.
McGreevy's command: 29 walks in 116 innings is the reason the Cardinals at 49c have the better starting pitching argument.
Cardinals bats: two runs in 18 innings in this series is the entire case for Toronto being favored despite a worse record.
Single-book risk: with no Polymarket Cardinals contract, the 49c has no second venue to arbitrate it.
Bullpen usage: Toronto has used its relief corps in back to back wins, which is what the first five innings run line at St. Louis -1.5 (33c) is pricing against.
Related Cardinals vs Blue Jays Markets
The season-long context for both clubs is priced elsewhere on the board: the Cardinals sit at 16c to make the 2026 playoffs and the Blue Jays at 10c to reach the postseason, which is where a 52-59 record and a 13.5 game deficit in the AL East lands a team in early August. Neither side registers on the 2026 World Series board. For the rest of Sunday's slate and every other live game board, see MLB markets.
Resolution Criteria
The moneyline resolves to the team that wins the game at Rogers Centre in Toronto on Sunday, August 2, 2026, with first pitch scheduled for 1:37 pm ET. The winning team contract pays $1 per share and the losing side settles at $0. Run line contracts (Toronto -1.5, St. Louis -1.5) and match total contracts (the 7.5 through 13.5 ladder) settle on the official final score, and the first five innings markets settle on the score after the fifth inning is complete. Kalshi and Polymarket both settle from the official MLB result once the game is final. If the game is postponed or suspended, each platform applies its published MLB postponement rules, which generally roll settlement to the makeup date rather than voiding. Rogers Centre has a retractable roof, so weather postponement risk on this game is low.
Key Factors
- Max Scherzer start for Toronto (1-4, 9.49 ERA, nine home runs allowed in 24.2 innings) is the largest single price variable
- Michael McGreevy (3.57 ERA, 1.20 WHIP over 116 innings) is the better starter on paper and the reason ESPN's model has St. Louis at 60.3% against a 49c price
- St. Louis has scored two runs across the first two games of the series and is 1-4 in its last five
- Polymarket lists no Cardinals moneyline contract, so the 49c is a single-book Kalshi quote with no cross-platform check
- Kalshi moneyline held flat at Toronto 52c and St. Louis 49c across all four overnight snapshots
- Match total 8.5 with the over at 55.5c is the second deepest pool on the board at $1.0K of Kalshi volume

As of August 2, 2026, Toronto is 51.5c on average (52c on Kalshi, 51c on Polymarket) and St. Louis is 49c on Kalshi. Polymarket does not list a Cardinals moneyline contract for this game, so the 49c is a single-book price.
Who is favored in Cardinals vs Blue Jays on August 2, 2026?
Toronto is favored at roughly 51.5% implied probability, a 2.5c edge over the Cardinals at 49c. It is one of the closest moneylines on the Sunday board, and the Kalshi pair sums to 101c, or 1c of vig.
Where can I trade the Cardinals vs Blue Jays market?
Kalshi lists both moneyline sides plus the run line, the full 7.5 through 13.5 total ladder, team totals, first five innings markets, and strikeout props. Polymarket lists the Toronto moneyline, totals, run lines, and home run props, but no Cardinals moneyline.
When does the Cardinals vs Blue Jays market resolve?
It resolves when the game goes final at Rogers Centre on Sunday, August 2, 2026. First pitch is 1:37 pm ET, and both platforms settle from the official MLB final score.
What is the Cardinals vs Blue Jays run line and total?
The match total is 8.5 runs with the over at 55.5c on August 2, 2026. Toronto -1.5 trades at 35c and St. Louis -1.5 at 37.5c, so the market gives the Cardinals a slightly better chance of winning by multiple runs.
What should I watch before Cardinals vs Blue Jays resolves?
Watch Max Scherzer's first two innings. He has allowed nine home runs in 24.2 innings, and Toronto at 52c is one early swing from repricing sharply. Also confirm the Cardinals starter on any strikeout prop, since Kalshi has that ladder posted under Matthew Liberatore rather than Michael McGreevy.
