Using your welcome bonus is straightforward, and I love finding a nice pay day here. If we place a $10 trade on today’s heaviest moneyline favorite, the Braves (-160), we’re looking at a profit of $6.25 if Atlanta secures the win. On the flip side, if you’re like me and enjoy chasing higher payouts, putting that same $10 on the day’s biggest underdog, the Giants (+134), returns a sweet $13.40 in profit if they manage to pull off the upset.
When I am handicapping today’s matchups to make my trades, a few massive statistical gaps jump off the page. The Dodgers roll into Petco Park with a lethal offense hitting .263 with a .788 OPS and 113 home runs, leaving the Padres’ .221 average, .663 OPS, and 83 homers in the dust. Los Angeles also holds a clear edge on the mound, boasting a 3.44 staff ERA compared to San Diego’s 3.90 ERA.
It is a similar story for the Yankees at Fenway Park. New York’s lineup has blasted 120 home runs with a .760 OPS, dwarfing Boston’s 69 homers and .699 OPS. Add in the Yankees’ stingy 3.32 team ERA versus the Red Sox’s 3.77 ERA, and these numbers point to New York being a phenomenal value trade today—especially given their status as slight moneyline underdogs.

Here is a pro tip from the trenches: you do not have to make a single trade worth $10. We can spread our predictions across multiple events—maybe piecing together a few smaller trades on today’s Yankees vs. Red Sox clash, or saving some ammo for the World Cup—as long as the cumulative sum of your trades reaches $10. Once you cross that $10 trading threshold, your $15 sign-up bonus becomes available to deploy.
