BetMGM Bonus Code Offers Two Paths for Red Sox vs Cardinals
The BetMGM bonus code COVERS50 provides two distinct welcome offers depending on your location. In most states where BetMGM operates, new users receive a $1,500 First Bet offer that returns their stake as bonus bets if the initial wager loses. Meanwhile, users in Colorado, Michigan, New Jersey, Pennsylvania, and West Virginia can choose the Bet $10, Get $150 promotion that awards bonus bets when their qualifying wager wins.
Both offers include $50 in BetMGM Rewards Points, which provide valuable benefits beyond sports betting. These points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. Saturday's Cardinals-Red Sox game presents an excellent opportunity to utilize either offer, whether you're backing Kyle Leahy's continued success as a starter or betting on Boston to break out of their offensive struggles.
For the $1,500 First Bet offer, losing wagers are returned as bonus bets that expire after seven days. Wagers over $50 receive five bonus bets worth 20% of the original stake each, while smaller wagers receive one bonus bet. The $150 bonus bet promotion awards three $50 bonus bets when your initial $10 wager wins, providing immediate value for successful predictions on Saturday's matchup.
- Minimum $10 deposit required for both offers
- Bonus bets expire seven days from issuance
- $50 BetMGM Rewards Points awarded instantly regardless of outcome
- Offer expires April 30, 2026 at 11:59 p.m. ET

Cardinals Look to Continue Hot Streak Against Struggling Red Sox
Saturday's game features contrasting storylines that create compelling betting opportunities for both BetMGM offers. St. Louis enters riding a season-high three-game winning streak, with Kyle Leahy making his transition from reliever to starter look seamless. The 28-year-old right-hander earned his first win in the rotation last Sunday against Detroit, allowing just two runs over five innings in a 5-3 victory.
Boston's offensive struggles continue to mount, managing five or fewer hits in four games this season. Ranger Suarez takes the mound for the Red Sox looking to improve on his 0-1 record and 8.64 ERA through two starts. The southpaw's recent outing against San Diego saw him surrender four runs in four innings, though he does carry a strong 1.13 ERA in two career starts against St. Louis.
Jordan Walker's hot streak adds another layer to Saturday's betting considerations. The young outfielder has hits in six straight games and homered in three consecutive contests before Friday's series opener. With the Cardinals' bullpen delivering scoreless relief work and Thomas Saggese providing clutch hitting, St. Louis appears well-positioned to extend their winning ways against a Red Sox team searching for offensive consistency.
