Since you get either cash winnings or a bonus bet, I suggest plus-money odds for your first bet, like a home run player prop. Josh Naylor has been a critical piece to the Mariners this postseason and I think he needs to produce offense if the Mariners can get the win in an elimination game.
Let's say you place $500 on Josh Naylor to hit 1+ home run (+800) with the BetRivers sportsbook bonus code offer.
- Tigers vs. Mariners Prediction: Josh Naylor 1+ home run (+800)
With the BetRivers promo code offer, if you win, you get the $500 stake back and $4,000 in cash profit. If you lose, you get a single $500 bonus bet, which expires within 30 days.
