Looking to back the Seattle Mariners or Philadelphia Phillies as they battle it out in their series finale? Score the ultimate boost to your bankroll with the Caesars Sportsbook promo code! Use code COVERS20X when registering to unlock the Double Your Winnings offer and receive 20 100% Profit Boosts after your first qualifying bet settles. You’ll find this and similar deals on our sportsbook promos page. ⚾💰
The Mariners are desperate to snap a four-game losing streak after falling in back-to-back games to the Phillies, despite a late-game rally and a strong effort from J.T. Realmuto. Manager Dan Wilson is keeping his squad motivated as right-hander Luis Castillo takes the mound, aiming to improve on his solid record against Philadelphia. Remember, you must wait for your first qualifying bet to settle before profit boost tokens are awarded—no matter if your initial wager wins or loses!

How the Caesars Sportsbook promo code works for Mariners vs Phillies
If you are a new user, the Caesars Sportsbook promo code gives you a straightforward path to serious profit-boosting. To qualify, register for an account using code COVERS20X, deposit at least $10, and place a qualifying wager of $1 or more. Once your first bet settles—win or lose—you’ll receive 20 profit boost tokens, each offering a chance to double your winnings on future bets. 🏟️⚡ These boosts are awarded regardless of whether your qualifying bet hits or misses.
Each profit boost token is good for up to $2,500 in potential profit, with a $25 maximum wager per token. You have 14 days from when they hit your account to use them, and each must be played individually. Minimum odds are -10,000, and the tokens cannot be combined. 🤑📅 Please note, bonus amounts are not included in your payout, and this offer is not available in all states. The real kicker? These boosts let you seriously amplify your potential payout on any eligible wager, making every swing or strikeout in Mariners vs Phillies even more electrifying!
Here’s how it plays out: place your first bet and wait for it to settle. After that, your 20 profit boost tokens will be credited to your account. These boosts can be used ONLY on future, eligible wagers—so your initial qualifying bet is not eligible for a boost. 🎯 After your first bet, you can use your profit boosts on upcoming Mariners vs Phillies matchups, other MLB games, or any eligible event. This sequence (qualifying bet, settlement, profit boosts, boosted bets) ensures you maximize your “Double Your Winnings” opportunity again and again. Remember, profit boost tokens are awarded regardless of your qualifying bet outcome!
