New customers can take advantage of an exclusive welcome offer ahead of the MLB games today by using the Polymarket promo code SOUTH during sign-up. Under this promotion, first-time users will get a $20 sign-up bonus after making an initial deposit of at least $20 to fund their account.

Once activated, these bonus funds can be used for today’s matchups—including the Baltimore Orioles visiting the Cleveland Guardians and the Seattle Mariners taking on the San Diego Padres—as well as any MLB game this week. We also have the last day of the NHL season on Thursday, along with the final NBA play-in games on Friday.

If you are eager to get in on today’s baseball action, this welcome offer provides immediate value. This promotion is strictly available to new Polymarket customers who are 18+ and physically located in an eligible Polymarket state. First-time users can secure a $20 sign-up bonus to use on any game across the daily MLB board.

To successfully unlock your extra funds, you must complete your registration and make an initial deposit of at least $20. Once your account is officially funded, the $20 bonus will be unlocked and ready to deploy on today’s slate.

MLB Probabilities on Thursday

MatchupProbability
BAL @ CLEBAL 46.96% / CLE 53.04%
COL @ HOUCOL 37.13% / HOU 62.87%
SEA @ SDSEA 52.39% / SD 47.61%

If you are looking to buy a $20 contract on today’s heaviest moneyline favorite, the Houston Astros, a winning ticket would yield a $10.47 profit. Conversely, taking a chance on the slate’s biggest underdog, the Colorado Rockies, would net a $31.60 profit.

When breaking down the COL @ HOU matchup, the Astros are heavily favored for good reason at the plate. Houston boasts a robust .269 team batting average and a .799 OPS, towering over the Rockies’ .235 average and .681 OPS. However, if you are looking for underdog hope, Colorado’s pitching staff holds a distinct statistical advantage. The Rockies own a 4.119 overall ERA, while Houston’s arms have struggled out of the gate with an injury-ravaged rotation.

Trade on the NHL and NBA Playoffs

While today’s MLB slate offers plenty of exciting action, your bonus funds provide even more flexibility. Beyond the diamond, you can also use your Polymarket account to make trades on the upcoming NHL and NBA playoffs.

Whether you are backing a heavy favorite on the hardwood or predicting a massive upset on the ice, your extra $20 sign-up bonus can be deployed across a wide variety of premier postseason markets.
