2025 MLB Sunday Night Baseball Betting
On the latest installment of Sunday Night Baseball we might actually see how the west was won. The tightest division race in MLB as we inch closer to the end of the regular season is in the AL West and the teams battling for the crown go head-to-head for the final time when the Houston Astros host the Seattle Mariners on September 21. First pitch from Daikin Park in Houston is scheduled for 7:15 p.m. ET on ESPN.
The Mariners are the hottest team in baseball extending their winning streak to 10 games with Tuesday’s 12-5 win over Kansas City. It was the fourth time during the streak they reached double figures in runs and the cause was aided by MVP candidate Cal Raleigh and Dominic Canzone. Canzone hit three home runs in the game yet was overshadowed by Raleigh, who blasted a pair giving him a MLB high 56 homers. The Astros aren’t going to let their run of four straight division titles and seven in the last eight seasons go without a fight. Despite a number of crippling injuries to their staff, the Astros beat Texas on Tuesday for their fourth win in five games to remain just a half-game behind the division leading M’s.
There will be plenty of betting options for the Sept. 21 showdown in the AL West between the Seattle Mariners and Houston Astros.

Seattle Mariners at Houston Astros
Hopefully for the Mariners they didn’t peak too early. The odds of them losing a game or two go up as their winning streak continues. And losing games to the Astros would be doubly bad. But what keeps them going is being so close to their first division title in 24 years and just their third since joining MLB in 1977. You can go down the list of power hitters the Mariners have had over the years. A few that stand out are Ken Griffey Jr., Alex Rodriquez and Jay Buhner. But no one in the history of the franchise has hit more homers in a single season Raleigh has hit in 2025. With two homers on Tuesday, Raleigh matched the season record set by Griffey with his 56, and he’s not finished.
Thanks to Raleigh’s power surge the M’s have the third most big flies in MLB and rank 10th in runs/game. During the winning streak Raleigh is hitting .316 with five homers and nine RBIs. The M’s scored at least five runs in seven of those games cashing the OVER seven times. Sunday’s probable Logan Gilbert has pitched well in his last five starts with a 2.54 ERA over 28.1 innings. Gilbert started the first game between the clubs back in April allowing only a Jose Altuve home run in 5.2 innings. He took a ND in the M’s 4-3 win.
Not only are the teams fighting for the division crown they’re also trying to stay in the wild card race. In a way they are playing playoff baseball right now. And that’s the way the season series has gone. The teams have split 10 games with five of them decided by a single run, two others by two runs and the other three were blowouts with Houston winning two of them. Houston ranks in the bottom third in runs per game and suffered a blow when Yordan Alvarez left Monday’s game with an ankle injury.
Jason Alexander has filled in nicely to stabilize a rotation jolted by injuries. He is 4-1 with a 2.76 ERA in 12 appearances with 11 starts since joining the club in June. He hasn’t allowed more than three earned runs in any of his last nine starts and the Astros are 9-0 in those games.

Betting Rules & Policies
Free Play Rules
- Free plays cannot be used on proposition bets.

- The maximum payout for any Free Play is $5,000.
- Free Plays that are left unused for 180 days will be removed from your account.
ROLLOVER
- Did you know that on all deposits made at BookMaker, there is a rollover requirement: an amount of betting action you must fulfill before you are eligible to make a withdrawal.
- Did you know that rollovers are calculated by multiplying the amount initially credited to your account a certain number of times? Yes! If you deposit without claiming any bonus, the rollover will always be 1x (one-time) your deposit amount. If you do claim a deposit bonus, the rollover will be higher and is based on the deposit plus bonus amount.
Wager disputes (claims)
If you disagree with any aspect of a wager you’ve placed, you are welcome to log an official dispute (commonly known as a “claim”). Claims must be reported no later than 15 (fifteen) calendar days following the settlement of the wager.
If following an initial review of the case there remains any doubt regarding the wager type, line, market, amount, or any other detail, the claim will be escalated to the BookMaker management team. All decisions made by them are final.
Wager Cash Out - How it works
With the Cash Out feature you can choose to eliminate a wager that's already been placed, and receive back either a portion, or your full stake amount.
Cash Out is selectively available on certain events, fixtures, and markets.
In order to see if a wager is eligible to be cashed out, simply navigate to your Bet Slip and check the 'My Open Bets' tab. If eligible, the Cash Out button will be displayed.
It’s also important to note that Cash Out is not contributing to any bonus or promotion including Bet Point accumulation and Rollover for releasing bonus cash.
