BetMGM Bonus Code SIBONUS50: Get $1,500 Back in Bonus Bets if Your First Bet Loses on Yankees vs. Phillies

The Yankees and Phillies square off Sunday night at Citizens Bank Park in a nationally televised matchup, and new bettors can capitalize on a welcome offer from BetMGM. Use the BetMGM bonus code 'SIBONUS50' to claim $1,500 back in bonus bets if your first wager loses. Check out sportsbook promos for more offers available on July 26.
How the BetMGM bonus code works for Yankees-Phillies
The BetMGM bonus code 'SIBONUS50' unlocks a welcome offer that protects your first wager on any sport or market, including Sunday's Yankees-Phillies matchup. After you register, deposit at least $10, and place your initial bet, BetMGM will return your entire stake in bonus bets if that wager loses, up to a maximum of $1,500. This means you can confidently place a substantial first bet on whether the Yankees will overcome Cristopher Sánchez's dominant left arm or if the Phillies' home-field advantage will prove decisive.
Here's how the bonus structure works. If you wager $1,500 and lose, you'll receive five bonus bets worth $300 each, totaling $1,500 in bonus credits. If you wager less than $50 and lose, you'll get one bonus bet matching your stake. These bonus bets expire seven days after they're issued, so you'll need to use them quickly on other games and sports. Additionally, you'll earn $50 in MGM Rewards Points regardless of whether your first bet wins or loses.
The terms are straightforward but important to understand. You must use the code 'SIBONUS50' during registration to qualify. Your initial deposit must be at least $10, and you must place a real money wager to trigger the offer. Bonus bets cannot be withdrawn as cash and must be used on future wagers before you can access any potential payout. When you use a bonus bet, BetMGM does not return your stake if that bet loses.
