MLB Games and Markets on Thursday Night
| Matchup | Probability |
|---|---|
| Atlanta Braves @ Arizona Diamondbacks | ATL 52.18% / AZ 47.82% |
| New York Mets @ San Francisco Giants | NYM 53.04% / SF 46.96% |
If you take that $20 and back today’s heaviest favorite on the morning line, the New York Mets, a winning ticket yields $16.13 in pure profit. On the flip side, if you’re feeling bold and back the slate’s biggest underdog, the San Francisco Giants, a $20 bet returns a sweet $20.80 in profit if they manage to pull off the upset at Oracle Park.
Atlanta boasts a stellar 2.00 team ERA and an elite 0.907 WHIP, vastly outperforming Arizona’s 4.588 ERA and 1.176 WHIP. Braves starter Reynaldo López is coming off a dominant, pain-free debut where his fastball touched 97 mph, while Arizona’s Ryne Nelson struggled with walks and home runs in his first outing.
The Mets carry a distinct statistical upper hand into the Bay Area. New York features a stout 2.497 team ERA, and starter David Peterson is fresh off 5 1/3 scoreless innings. They are facing a Giants squad managing a meager .201 batting average and a .264 OBP.
Beyond Baseball: Expanding Your Predictions
While I love grinding out an edge on the diamond, there is nothing better than having options. Your bonus funds aren’t just locked into baseball. New Polymarket customers can take their $20 bonus and jump into the hardwood action with the NBA playoffs approaching, or lay down a prediction on the highly anticipated college hoops Final Four.
If traditional sports aren’t your only angle, Polymarket also offers incredibly unique prediction markets where you can trade shares on pop-culture events, weather outcomes, elections, and much more. It’s the perfect way to diversify your portfolio and chase bigger payouts across the board.
