8:10 p.m. ET: St. Louis Cardinals at Houston Astros (-140, 9)
The Cardinals (10-8) just took two of three against the Guardians, winning the series finale 5-3 as a -110 home pick’em. Similarly, the Astros (8-12) just won two of three against the Rockies but failed to complete the sweep, dropping the series finale 3-2 as -175 home favorites.
In tonight’s Interleague series opener, the Cardinals tap righty Kyle Leahy (1-2, 5.14 ERA) and the Astros go with fellow righty Peter Lambert, who is making his 2026 debut. Lambert last pitched in the majors in 2024, going 2-5 with a 5.72 ERA for the Rockies. He posted a 1.84 ERA in the minors this season before being called up to the bigs.
This line opened with Houston listed as a -135 home favorite and St. Louis a +115 road dog.
Sharps have laid the wood with the Astros at home, pushing Houston up from -135 to -140, with some shops inching up to -145.
At Circa, the Astros are receiving only 33% of moneyline bets but a whopping 89% of moneyline dollars, a massive “low bets, higher dollars” sharp split in their favor from the wiseguys in Vegas.
Pros have also gotten down hard on the Astros run-line (-1.5 at +155), as Houston is taking in only 42% of spread bets but 86% of spread dollars at DraftKings.
Home favorites off a loss in the opening game of a new series, like the Astros here, are 18-9 (67%) with a 10% ROI this season. Interleague home favorites who missed the playoffs the previous season facing an opponent who also missed the playoffs the previous season are 112-70 (62%) with a 3% ROI since 2025.
Houston has a big edge at the plate, hitting .264 with 107 runs scored compared to St. Louis hitting .231 with only 80 runs scored.
The Astros are hitting .265 against righties (5th in MLB) while the Cardinals are only hitting .221 (26th).
9:40 p.m. ET: Chicago White Sox at Athletics (-160, 9)
The White Sox (6-13) just got swept by the Rays, losing yesterday’s series finale 5-3 as +110 home dogs. Meanwhile, the Athletics (10-9) just split a four-game series against the Rangers, dropping yesterday’s series finale 9-6 as a -110 home pick’em.
In tonight’s series opener, the White Sox send out righty Davis Martin (2-1, 2.50 ERA) and the Athletics turn to fellow righty Aaron Civale (2-0, 1.72 ERA).
This line opened with the Athletics listed as a -145 home favorite and the White Sox a +125 road dog.
Sharps have jumped on the A’s at home, steaming the Athletics up from -145 to -160.
At Circa, the A’s are taking in over 90% of moneyline bets and dollars, a massive one-way bet split in their favor from the wiseguys in the desert.
We’ve also seen a flood of sharp action hit the A’s run-line (-1.5 at +120), as the A’s are taking in 71% of spread bets and 79% of spread dollars at DraftKings.
The Athletics have betting system value as a non-division favorite, with the lack of familiarity benefiting the “better” team who is expected to win.
Home favorites off a loss in the opening game of a new series, like the A’s here, are 18-9 (67%) with a 10% ROI this season.
The Athletics have the edge at the plate, hitting .234 with 78 runs scored and a .310 OBP compared to the White Sox hitting .195 with only 60 runs scored and a .286 OBP.
The A’s are 4-3 at home this season. The White Sox are 3-7 on the road.
This is also a schedule advantage for the A’s, who continue a homestand while the White Sox must travel west to California.
9:40 p.m. ET: Texas Rangers at Seattle Mariners (-130, 6.5)
The Rangers (10-9) just split a four-game series against the Athletics, winning yesterday’s series finale 9-6 as a -110 road pick’em. On the other hand, the Mariners (8-12) just got swept by the Padres, losing yesterday’s series finale 5-2 as -125 road favorites.
In tonight’s series opener, the Rangers start righty Jacob deGrom (1-0, 2.87 ERA) and the Mariners go with fellow righty Logan Gilbert (1-2, 4.18 ERA).
This line opened with Seattle listed as a -120 home favorite and Texas a +100 road dog.
The public is largely split down the middle and can’t decide who to take. However, despite this roughly 50/50 moneyline ticket split at DraftKings we’ve seen the Mariners creep up from -120 to -130.
Normally, in a vacuum, a line shouldn’t move at all if the bets are even because, theoretically, the oddsmakers have balanced action and no need to adjust the price one way or the other. So, based on the line move we can infer that the bigger, sharper wagers have sided with Seattle at home.
At DraftKings, the Mariners are receiving 52% of moneyline bets but 64% of moneyline dollars, a sharp “low bets, higher dollars” bet split and further evidence of respected wiseguy action backing the modest home chalk.
Home favorites off a loss in the opening game of a new series, like the Mariners here, are 18-9 (67%) with a 10% ROI this season. If they also made the playoffs the previous season, like Seattle, they improve to 12-5 (71%) with a 14% ROI this season.
Seattle has correlative betting value as a favorite in a super low total game (6.5), with the fewer amount of expected runs scored more likely to come from the “better” team who is expected to win.
The Mariners have struggled on the road (1-8) but have gone 7-4 at home this season.
