With our promo code activated, you can immediately apply your $20 sign-up bonus to tonight’s baseball slate. There is nothing better than playing with house money! Consider using your bonus capital on the highly anticipated cross-town rivalry at Wrigley Field, where the Chicago Cubs (73-53) host the Chicago White Sox (65-59) in a primetime showdown. Tensions are boiling over on both sides of town following recent bleacher drama and Pete Crow-Armstrong’s historic walk-off homer last night, making this the perfect spot to find some value.

To take advantage of this exclusive offer, new Polymarket customers simply need to create an account and execute an initial trade of at least $10. Once that qualifying trade clears, you will receive $20 in bonuses.

If you were to use your $20 in bonuses to back today’s heaviest moneyline favorite, the Boston Red Sox, a winning ticket would return a profit of $12.15. Conversely, taking a chance with a $20 trade on the biggest underdog on the board, the Arizona Diamondbacks, would net a $28.50 profit if they pull off the road upset.

I’m making these trades with a close eye on the statistics. Looking at that pivotal ARI @ BOS matchup, the Red Sox stats scream heavy home favorites. Boston boasts a distinct advantage on the mound, carrying a 3.50 overall team ERA into the contest compared to Arizona’s 4.13. With Ranger Suรกrez taking the bump for Boston against Arizona’s Merrill Kelly, who has struggled mightily in recent outings, the Red Sox are an appealing anchor for your trades today. They also hold the edge offensively, generating a .724 team OPS and a .249 batting average, outperforming the Diamondbacks’ .712 OPS and .243 average.
