BetMGM Odds for Mariners vs. Tigers, MLB game

The Seattle Mariners are looking to push their winning momentum forward as they travel to Detroit to finish out their weekend series. Seattle comes into this game sitting at 34-31 and leading the AL West, largely backed by solid pitching outings. Luis Castillo takes the mound for Seattle, carrying a 2-5 record but holding immense potential to shut down opposing lineups on any given afternoon.

The Detroit Tigers are looking to bounce back in front of their home crowd at Comerica Park. Facing a 26-39 record this season, the Tigers are handing the baseball to Jack Flaherty. Flaherty has struggled to lock down wins this year, sitting at 1-7, but a strong performance against Seattle's bats could turn things around for Detroit. Using your BetMGM Sportsbook promo code on this game gives you plenty of ways to explore standard lines or specialized props.

Below are the current betting lines available at the sportsbook for Sunday's matchup.

Expert Picks and Chances to use BetMGM Promo Code WSNSPORTS for Mariners vs. Tigers, MLB game

When you are looking to deploy your promotion, your strategy should change based on which offer is available in your home state. Here is a look at how to get the most theoretical utility out of your specific bonus:

• Maximizing the First Bet Offer ($1,500 Max): If you are in a first bet safety net state, the math favors taking a moderate underdog or a plus-money line. Since a loss means you get your stake back as a bonus credit, betting on a line like Seattle covering the spread (-1.5 at +135) or backing Detroit to win straight up (+100) offers a higher potential payout if the bet hits, with the bonus backing you up if it fails.

• Maximizing the Bet and Get Offer ($150 Bonus): If you are in MI, NJ, PA, or WV, your goal is simply to win the $10 bet to claim the $150 bonus block. In this scenario, backing the favored moneyline team is the logical play. Seattle at -102 represents the statistically safer route to secure a victory and trigger your bonus bets.

• Targeting Pitcher Props: Luis Castillo has standard high strikeout potential despite his win-loss record. Exploring the over on his total strikeouts can be an alternative way to utilize your promotional wager without worrying about which bullpen closes out the 9th inning.
