1:35 p.m. ET: San Francisco Giants at Baltimore Orioles (-130, 8.5)
This is the rubber match of a three-game Interleague series.
The Giants (6-9) took the opener 6-3, cashing as +105 road dogs. Then the Orioles (7-7) secured a 6-2 win yesterday, coming through as +100 home dogs.
In this afternoon’s series finale, San Francisco starts righty Adrian Houser (0-1, 3.97 ERA) and the Orioles rebuttal with lefty Cade Povich (0-0, 3.18 ERA).
This line opened with Baltimore listed as a -130 home favorite and San Francisco a +110 road dog.
The pubic is all over the Orioles laying modest chalk at home. However, despite receiving 65% of moneyline bets at DraftKings we’ve seen Baltimore remain static at -130, with a few other books inching down to Orioles -125.
Normally, if a team is garnering two-thirds of tickets you would expect to see the line rise in their favor. However, the fact that the line hasn’t budged or even dipped slightly away from Baltimore indicates a sharp line freeze and smart money liability on the plus money Giants (+110).
At Circa, San Francisco is only taking in 44% of moneyline bets but a whopping 93% of moneyline dollars, a massive “low bets, higher dollars” sharp contrarian split in their favor.
Dogs are 102-116 (47%) with a 7% ROI this season. Sunday dogs are 17-11 (61%) with a 42% ROI this season, the best day of the week for dogs.
San Francisco is hitting .289 against lefties this season, 2nd best in MLB.
2:15 p.m. ET: Boston Red Sox (-125, 9) at St. Louis Cardinals
This is the rubber match of a three-game Interleague series.
The Cardinals (8-6) won the opener 3-2, hanging on as +115 home dogs. Then the Red Sox (5-9) bounced back with a 7-1 win yesterday, taking care of business as -140 road favorites.
In this afternoon’s series finale, the Red Sox send out righty Brayan Bello (0-1, 9.00 ERA) and the Cardinals turn to fellow righty Andre Pallante (1-0, 1.80 ERA).
This line opened with Boston listed as a -130 road favorite and St. Louis a +110 home dog.
The public is happy to lay the short chalk with the Red Sox, who are taking in 66% of moneyline bets at DraftKings.
However, despite receiving a majority of tickets we’ve seen Boston fall from -130 to -125, with some shops inching further down to -120. This signals sharp reverse line movement on the Cardinals, as the line has moved in their favor (+110 to +105) despite receiving a minority of tickets.
At DraftKings, St. Louis is taking in 34% of moneyline bets and 41% of moneyline dollars, a sharp “low bets, higher dollars” split in favor of the home dog.
Home dogs, like the Cardinals here, are 41-35 (54%) with an 18% ROI this season. Short home dogs +120 or less are 305-272 (53%) with an 8% ROI since 2025.
St. Louis has additional correlative betting value as a dog in a high total game (9), with the more expected runs scored leading to more variance and upset opportunities.
2:20 p.m. ET: Pittsburgh Pirates at Chicago Cubs (-135, 12.5)
The Pirates (9-5) have taken the first two game of this three-game series, winning the opener 2-0 as +130 road dogs and then winning again yesterday 4-3 in extra innings as +125 road dogs.
In this afternoon’s series finale, the Pirates tap righty Bubba Chandler (0-1, 3.12 ERA) and the Cubs (6-8) go with fellow righty Jameson Taillon (0-1, 2.53 ERA).
This line opened with Chicago listed as a -135 home favorite and Pittsburgh a +115 road dog.
Gambler’s Fallacy says there’s no way the Cubs get swept at home and 64% of moneyline bets at DraftKings are laying the wood with Chicago at home.
However, despite receiving a majority of tickets we’ve seen Chicago remain stagnant at -135. This signals a sneaky sharp line freeze on the Pirates (+115), as the line has remained the same despite the public pounding the Cubs. In other words, books seem reluctant to hand out more plus money to Pittsburgh even though they are the unpopular play.
Dogs off a win, like the Pirates here, are 53-49 (52%) with a 15% ROI this season.
Pittsburgh has additional betting system value as a divisional dog, with the built in familiarity and rivalry aspect leveling the playing field and benefiting the team getting plus money.
The Pirates also have correlative betting value as a dog in a super high total game (12.5), with the more expected runs scored leading to more variance and upset opportunities.
