Baseball fans looking for a real chance at a nice pay day today need to check out the OG promo code TSNEWS. Sign up here to redeem a $10 bonus that unlocks after making just $10 in trades.
I'm using this exact bonus to handicap today's exciting matchups—like the Milwaukee Brewers visiting the Chicago Cubs and the Philadelphia Phillies taking on the Arizona Diamondbacks. You can use it on today's slate or any other MLB game throughout the week. There is nothing better than getting a little extra bankroll to chase those bigger payouts, so let's dive into how we can make the most of this.

How the Offer Works
Available exclusively for new OG customers, this welcome offer hands us a $10 sign-up bonus to kickstart our prediction market portfolio. Claiming it is a breeze. Just register your account and make a first-time deposit of at least $1. Once you're funded, that $10 bonus unlocks the moment you make $10 in total trades on their prediction markets.
Because OG is available in all 50 states, players across the country who are at least 18 years old can jump right into the trenches with us. Once you secure your bonus, you can apply your trades to predicting exciting matchups on today's MLB slate.
Whether you want to predict the outcome of the New York Yankees visiting the Los Angeles Angels, or you prefer finding value on the Chicago White Sox squaring off against the Houston Astros, OG offers a completely unique way to engage with baseball.
Make Trades Before and During MLB Games
| MIL @ CHC | MIL -101 / CHC -110 | MIL 49.0% / CHC 51.0% |
| OAK @ TEX | OAK +189 / TEX -213 | OAK 33.7% / TEX 66.3% |
| CHW @ HOU | CHW +117 / HOU -129 | CHW 45.0% / HOU 55.0% |
| NYY @ LAA | NYY -141 / LAA +121 | NYY 56.4% / LAA 43.6% |
| PHI @ ARI | PHI -121 / ARI +103 | PHI 52.6% / ARI 47.4% |
Let's look at the math, because finding the right value on the board is how we build a winning strategy. If you deploy your $10 welcome bonus on today's heaviest moneyline favorite, the Texas Rangers (-213), a winning prediction would net you $4.69 in profit. Conversely, if you're like me and prefer chasing higher payouts, backing the day's biggest underdog—the Oakland Athletics (+189)—would return a lucrative $18.90 profit on that same $10 trade if they pull off the upset.
Before locking in your trades, digging into the team statistics can help identify the smartest values. In the tightly contested Brewers vs. Cubs matchup, Milwaukee brings a stout 3.37 overall team ERA to the mound compared to Chicago’s 4.145 ERA. This pitching advantage makes the Brewers an incredibly intriguing pick at essentially even odds (-101).
Meanwhile, in the clash between the Phillies and Diamondbacks, the offensive production has been remarkably similar all season, but Philadelphia boasts a slight edge in run prevention. The Phillies' staff holds a 4.054 overall ERA, marginally better than Arizona's 4.184 ERA. I'm placing these bets because that slight pitching edge entirely justifies Philadelphia's position as the road favorite (-121) in tonight's desert showdown.
