Where to bet on 2025 MLB Playoffs

The DraftKings promo code, FanDuel promo code and bet365 bonus code offers are all “bet and get” promotions, though only bet365 is giving out bonus bets regardless of whether a user’s first bet wins or loses. FanDuel is offering the most money in bonus bets with $300.

The BetMGM bonus code is offering up to $1,500 in bonus bets if your qualifying wager loses. Depending on the state you live in, you may be eligible for the company’s other promotion, which gives users $150 in bonus bets if their first wager of $10 or more wins. The Fanatics Sportsbook promo code is spreading out its bonus bets offering across five days. Users must wager at least $10 on odds of -500 or longer and will be rewarded with $50 in FanCash regardless of the outcome.

The Caesars Sportsbook promo code is going with profit boosts instead of bonus bets for its promotion, offering 20 100% profit boosts after users wager $1 or more with the sportsbook.

MLB playoffs betting preview, picks for Tuesday

Both the Mariners and Tigers will be attempting to take a 2-1 series lead when the two sides face off at Comerica Park. Logan Gilbert (6-6, 3.44 ERA) gets the nod for Seattle, and he’s given up just seven runs across his last five starts. The Tigers are going with Jack Flaherty (8-15, 4.64 ERA), who gave up just one run in 4 2/3 innings in a 6-3 win over the Guardians. The Mariners are -137 favorites (wager $137 to win $100) in the latest SportsLine consensus odds, and the model backs them to win in 57% of simulations. 

The Yankees are attempting to keep their season alive and will send ace lefty Carlos Rodon (18-9, 3.06 ERA) to the bump Tuesday. Rodon gave up three runs in six innings in his appearance against the Red Sox, but the Yankees did win that game 4-3. The Blue Jays will try to advance to the ALCS behind Shane Bieber (4-2, 3.57 ERA). Bieber missed most of the season but has pitched well of late, winning two of his last three starts. The SportsLine Projection Model lists the Yankees as -157 favorites (wager $157 to win $100), but the Blue Jays offer more value based on simulation results. Toronto covers the run line in 67% of simulations and wins in 43% as a +130 money line underdog (wager $100 to win $130).

Responsible gaming

Responsible gaming is important at all sportsbooks, which offer tools like setting betting limits, taking timeouts and self-exclusion measures to all their users. Some sportsbooks like DraftKings and BetMGM have live chat functions on their platforms for users to get in touch with the support team 24/7. All sportsbooks have contact information for helplines, like 1-800-GAMBLER, on their platforms for those who need further assistance.
