How the Fanatics Sportsbook promo works for the Mariners vs Tigers Game 4 and what you need to know
The Fanatics Sportsbook promo gives new users a seamless way to boost their action on the Mariners vs Tigers Game 4. This postseason matchup sees Detroit calling on Casey Mize, the former No. 1 pick, to help stave off elimination against a hot Seattle team. The Mariners, leading 2-1 in the series, are on the brink of their first American League Championship Series trip since 2001. With Bryce Miller starting for Seattle and both teams’ lineups featuring heavy hitters, this is an ideal contest to try the welcome offer.
Here’s how the Fanatics Sportsbook promo works for this game:
- The welcome offer automatically activates when you register; no promo code is required.
- To qualify, deposit at least $10 and place a minimum $50 wager at odds of -500 or longer.
- The bonus delivers $250 total in FanCash, issued as $50 per day for five consecutive days.
- FanCash is credited within 72 hours of each qualifying day.
- FanCash is non-withdrawable but can be used to place additional bets across any available market, including Mariners vs Tigers Game 4 props, sides, or totals.
- FanCash expires seven days (168 hours) after it is issued each day.
- For example, if you bet $50 on Seattle to clinch the series behind Bryce Miller’s stellar postseason debut, or back Detroit to force a Game 5 behind Mize’s arm, you will receive your daily $50 FanCash regardless of your wager’s outcome.
- This promotion is live through October 12, 2025, but is not available in New York state.
This built-in offer is a great way to add value, whether you believe in the Mariners’ postseason momentum or are banking on Tigers’ bats bouncing back.
