6:40 p.m. ET: Miami Marlins at Detroit Tigers (-145, 8.5)
The Marlins (8-5) just split a four-game series against the Reds, winning yesterday’s series finale 8-1 as -125 home favorites. On the other hand, the Tigers (4-9) just got swept by the Twins, losing 3-1 yesterday as -145 road favorites.
In tonight’s Interleague series opener, the Marlins hand the ball to righty Chris Paddack (0-1, 8.31 ERA) and the Tigers turn to fellow righty Keider Montero (0-1, 4.15 ERA).
This line opened with Detroit listed as high as a -155 home favorite and Miami a +130 road dog.
The public expects the Tigers to get back on track and 61% of moneyline bets at DraftKings are laying the chalk with the Tigers at home.
However, despite receiving a majority of tickets we’ve seen Detroit fall from -155 to -145. This signals sharp reverse line movement grabbing the plus money with Miami, causing the line to move toward the Fish (+130 to +120) even though the public is backing the Tigers.
While the Marlins are contrarian at DraftKings, Miami is taking in 86% of moneyline bets and over 90% of moneyline dollars at Circa, signaling heavy smart money out in Vegas backing the road dog.
Dogs are 87-101 (46%) but have produced a 6% ROI this season. Sweet spot dogs +120 to +150 have gone 35-30 (54%) with a 26% ROI this season.
Miami has additional betting system value as a dog in a high total game (8.5 juiced over -115), with the more expected runs scored leading to more variance and upset opportunities.
Miami has been far better at the plate, hitting .269 with 67 runs scored compared to Detroit hitting .233 with only 54 runs scored.
7:10 p.m. ET: New York Yankees (-130, 8) at Tampa Bay Rays
The Yankees (8-4) just dropped two of three against the Athletics, losing yesterday’s series finale 1-0 as -200 home favorites. Similarly, the Rays (5-7) just lost two of three against the Cubs, dropping the series finale 6-2 as -115 home favorites.
In tonight’s series opener, the Yankees turn to righty Luis Gil, who is making his 2026 debut after going 4-1 with a 3.32 ERA in 2025. Meanwhile, the Rays counter with lefty Steven Matz (2-0, 4.09 ERA).
This line opened with New York listed as a -140 road favorite and Tampa Bay a +120 home dog.
The public is all over New York and 86% of moneyline bets at DraftKings are laying the modest chalk with the Bronx Bombers.
However, despite receiving such lopsided support we’ve seen New York fall from -140 to -130. This signals sharp reverse line movement on Tampa Bay, as the the line has moved toward the Rays (+120 to +110) despite the public pounding the Yankees.
At DraftKings, Tampa Bay is taking in only 14% of moneyline bets but 30% of moneyline dollars, a sharp contrarian “low bets, higher dollars” bet split in their favor.
Home dogs are 37-34 (52%) with a 15% ROI this season. Short home dogs +120 or less are 302-271 (53%) with an 8% ROI since 2025. When both teams are coming off a loss, as is the case here, the dog taking in 10-cents of line movement or more has gone 15-14 (52%) with a 21% ROI since 2025.
Tampa Bay has additional betting system value as a divisional dog, with the built in familiarity leveling the playing field and benefiting the team taking in plus money.
The Rays also enjoy a “rest vs tired” advantage, as Tampa Bay was off yesterday while the Yankees played in New York and now must travel south to Florida.
8:15 p.m. ET: Boston Red Sox (-145, 7.5) at St. Louis Cardinals
The Red Sox (4-8) just took two of three against the Brewers, winning the series finale 5-0 as -140 home favorites. Similarly, the Cardinals (7-5) just won two of three against the Nationals, taking the series finale 6-1 as -125 road favorites.
In tonight’s Interleague series opener, the Red Sox tap lefty Connelly Early (0-0, 2.89 ERA) and the Cardinals go with righty Dustin May (0-2, 15.95 ERA).
This line opened with Boston listed as high as a -145 road favorite and St. Louis a +125 home dog.
The public is rushing to the window to back Boston, as the Red Sox are receiving 66% of moneyline bets at DraftKings.
However, despite receiving a clear majority of tickets the Red Sox have remained largely static at -145. This signals a sharp contrarian line freeze on the Cardinals +125, as the line hasn’t budged despite the public hammering Boston.
St. Louis is one of the top “bet against the public” plays of the day as the Cardinals are only receiving 34% of moneyline bets at DraftKings.
However, at Circa the Cardinals are taking in 55% of moneyline bets and 71% of moneyline dollars, a sharp “low bets, higher dollars” bet split in their favor from the wiseguys in the desert.
Home dogs are 37-34 (52%) with a 15% ROI this season. When both teams are coming off a win, as is the case here, the home dog has gone 40-24 (63%) with a 34% ROI since 2025.
The Cardinals are hitting .271 against lefties this season, 3rd best in MLB.
St. Louis is 4-2 at home this season. Boston is 1-5 on the road.
