6:40 p.m. ET: St. Louis Cardinals at Pittsburgh Pirates (-125, 8.5)
The Cardinals (16-13) have won the first two games of this four-game series, taking the opener 4-2 as +100 road dogs and then winning again yesterday 11-7 as +130 road dogs.
In tonight’s rematch, the Cardinals hand the ball to righty Andre Pallante (2-2,, 4.26 ERA) and the Pirates (16-14) turn to fellow righty Bubba Chandler (1-2, 4.88 ERA).
This line opened with Pittsburgh listed as a -150 home favorite and St. Louis a +130 road dog.
Gambler’s Fallacy says the Cardinals can’t possibly win again on the road and 60% of moneyline bets at DraftKings are laying the chalk with the Pirates to get back on track.
However, despite receiving a majority of tickets we’ve seen the Pirates tumble from -150 to -125. This signals sharp reverse line movement on the Cardinals to keep rolling, as the line has moved in St. Louis’ favor (+130 to +105) despite being the unpopular play.
At DraftKings, the Cardinals are receiving 40% of moneyline bets and 50% of moneyline dollars. At Circa, the Cardinals are taking in 43% of moneyline bets and a whopping 95% of moneyline dollars. Both books are showing a notable “low bets, higher dollars” sharp contrarian split in favor of the road dog.
St. Louis has betting system value and correlative betting value as a divisional dog in a high total game (8.5), with the built in familiarity and more expected runs scored leveling the playing field and leading to more upset opportunities.
Pallante has a 2.70 ERA on the road compared to 5.28 at home. Meanwhile, the Pirates are 1-3 in Chandler’s last four starts. He has posted a 5.95 ERA in those four starts, giving up 13 earned runs in 19.2 innings pitched.
The Cardinals are 15-12 (56%) with an 18% ROI as a dog this season, the 4th most profitable dog in MLB.
6:40 p.m. ET: San Francisco Giants at Philadelphia Phillies (-145, 7)
The Phillies (10-19) took last night’s series opener 7-0, cruising as -160 home favorites.
In tonight’s rematch, the Giants (13-16) tap righty Logan Webb (2-3, 4.86 ERA) and the Phillies rebuttal with lefty Cristopher Sanchez (2-2, 2.94 ERA).
This line opened with Philadelphia listed as a -135 home favorite and San Francisco a +115 road dog.
Wiseguys are going back to the well with the Phillies, steaming Philadelphia up from -135 to -145.
At DraftKings, the Phillies are receiving 76% of moneyline bets and 84% of moneyline dollars, a one-way “low bets, higher dollars” Pro and Joe bet split in their favor.
Pros have also gotten down on the Phillies run-line (-1.5 at +155), as Philadelphia is taking in 58% of spread bets and a whopping 90% of spread dollars at DraftKings.
Non-division home favorites off a win priced -150 or less with line movement in their favor, like the Phillies here, are 126-83 (60%) with a 7% ROI since 2025. When both teams are below .500, the home favorite off a win is 96-58 (62%) with a 2% ROI since 2025.
Philadelphia has correlative betting value as a favorite in a low total game (7), with the fewer amount of expected runs scored more likely to come from the “better” team who is expected to win.
Sanchez is 2-1 with a 1.16 ERA at home this season.
7:40 p.m. ET: Arizona Diamondbacks at Milwaukee Brewers (-125, 8.5)
The Brewers (15-13) dominated last night’s series opener 13-2, taking care of business as -135 home favorites.
In tonight’s rematch, the Diamondbacks (15-13) send out lefty Eduardo Rodriguez (2-0, 2.89 ERA) and the Brewers counter with righty Brandon Sproat (0-1, 6.45 ERA).
This line opened with Milwaukee listed as a -115 home favorite and Arizona a -105 road dog.
Sharps have pounced on the Brewers laying short chalk at home, steaming Milwaukee up from -115 to -125, with a few other books touching as high as -130.
At Circa, Milwaukee is taking in 54% of moneyline bets and 59% of moneyline dollars, a “low bets, higher dollars” bet split signaling slight public support but also respected sharp action on the home team.
We’ve also seen smart money back the Brewers on the run-line (-1.5 at +160), as Milwaukee is taking in over 90% of spread bets at dollars at Circa.
Non-division home favorites off a win priced -150 or less with line movement in their favor, like the Brewers here, are 126-83 (60%) with a 7% ROI since 2025.
Milwaukee has the more productive bats, posting a .335 OBP with 145 runs scored compared to Arizona posting a .208 OBP with 134 runs scored.
The Brewers are 9-7 at home. The Diamondbacks are 6-7 on the road.
