6:35 p.m. ET: Arizona Diamondbacks at Baltimore Orioles (-165, 9)
The Orioles (9-7) won last night’s Interleague series opener 9-7, coming from behind as -130 home favorites.
In tonight’s rematch, the Diamondbacks (9-8) hand the ball to righty Merrill Kelly, who is making his 2026 debut after going 12-9 with a 3.52 ERA in 2025. Meanwhile, the Orioles counter with lefty Trevor Rogers (2-0, 1.89 ERA).
This line opened with Baltimore listed as a -145 home favorite and Arizona a +125 road dog.
Sharps have laid the wood with the Orioles to earn another victory at Camden Yards, steaming Baltimore up from -145 to -165.
At DraftKings, the Orioles are taking in 63% of moneyline bets and 68% of moneyline dollars. At Circa, Baltimore is receiving 67% of moneyline bets and a whopping 99% of moneyline dollars. Both books are showing a “low bets, higher dollars” sharp split in favor of the home chalk, especially from the pros out in Vegas.
Interleague home favorites in the second game of a series after winning the opener are 58-34 (63%) with a 3% ROI since 2025. When two teams who both missed the playoffs the previous season face off, the Interleague favorite is 110-67 (62%) with a 4% ROI since 2025.
Baltimore has the better bats, hitting .249 with a .336 OBP compared to Arizona hitting .229 with a .287 OBP.
The Orioles are 3-0 in Rogers’ three starts this season. He is 2-0 with a 1.38 ERA in two starts at home.

7:15 p.m. ET: Miami Marlins at Atlanta Braves (-165, 8.5)
The Marlins (9-8) stole last night’s series opener 10-4, coming through as +125 road dogs.
In tonight’s rematch, the Marlins send out righty Max Meyer (1-0, 3.68 ERA) and the Braves go with fellow righty Reynaldo Lopez (1-0, 1.15 ERA).
This line opened with Atlanta listed as a -150 home favorite and Miami a +130 road dog.
Sharps are counting on the Braves to bounce back with a win, steaming Atlanta up from -150 to -165.
At DraftKings, the Braves are receiving 73% of moneyline bets and 85% of moneyline dollars. At Circa, Atlanta is taking in over 90% of moneyline bets and dollars. Both books are showing a one-way Pro and Joe bet split in favor of the home chalk.
We’ve also seen smart money lean on the Braves run-line (-1.5 at +135), as Atlanta is taking in 68% of spread bets and 76% of spread dollars at DraftKings.
Atlanta has the edge at the plate, hitting .274 with 94 runs scored compared to Miami hitting .259 with 80 runs scored.
The Braves are 3-0 in Lopez’s three starts. He has allowed 1 earned run or fewer in all three starts.

9:40 p.m. ET: Seattle Mariners (-120, 7) at San Diego Padres
The Mariners (8-9) just swept the Astros, winning yesterday’s series finale 6-2 as -180 home favorites. Similarly, the Padres (10-6) just swept the Rockies, winning the series finale 7-2 as -225 home favorites.
In tonight’s Interleague series opener, the Mariners tap righty Bryan Woo (0-1, 1.50 ERA) and the Padres turn to fellow righty Michael King (1-1, 3.24 ERA).
This line opened with Seattle listed as a -125 road favorite and San Diego a +105 home dog.
The public is happy to lay the short chalk with Seattle, with 65% of moneyline bets at DraftKings coming down in favor of the Mariners.
However, despite receiving roughly two-thirds of tickets we’ve seen Seattle fall from -125 to -120.
This signals sharps reverse line movement on the Padres, as the line has moved in San Diego’s favor (+105 to +100) despite the public backing Seattle.
At DraftKings, the Padres are only taking in 35% of moneyline bets but 40% of moneyline dollars, a sharp contrarian “low bets, higher dollars” bet split in their favor.
Dogs off a win, like the Padres here, are 58-57 (50%) with a 12% ROI this season. Home dogs are 43-39 (52%) with a 15% ROI this season. When both teams are coming off a win, as is the case here, the home dog is 42-25 (63%) with a 35% ROI since 2025.
San Diego has the superior offense, hitting .274 with 74 runs scored compared to Seattle hitting .208 with 69 runs scored.
The Padres are 6-4 at home this season. The Mariners are 1-5 on the road.
San Diego also enjoys a “rest vs tired” advantage, as the Padres were off yesterday and continue a homestand while the Mariners played yesterday in Seattle and now must travel to Southern California.
