Just keep in mind, we’re keeping things above board: you must be 18+ and physically present in an eligible state to participate.
Trade Before and During MLB Games
Let’s look at the morning line and see where we’re placing our trades today.
| Matchup | Probability (Vig-Free) |
|---|---|
| NYM @ SD | NYM 49.89% / SD 50.11% |
| SF @ CHC | SF 46.88% / CHC 53.12% |
If you want to play it safe and trade your $20 deposit on the Chicago Cubs, a winning ticket returns a pure profit of $16.00. But if you’re like me and love the thrill of a live dog, placing that same $20 on the board’s heaviest underdog, the San Francisco Giants, hands us a solid $20.80 profit if they pull off the road upset.
When I’m handicapping these games, the NYM @ SD matchup screams value to me. Despite being slight underdogs, the Mets are bringing a superior team batting average to the plate (.228 vs. San Diego’s .215) and a much stronger pitching staff, boasting a 3.771 collective ERA compared to the Padres’ 3.951.
As for the SF @ CHC clash, the Cubs definitely justify their favorite status on the mound with a 4.349 team ERA against the Giants’ 4.558. However, San Francisco has a real offensive edge, hitting .260 as a team over Chicago’s .240. That makes the Giants a very dangerous underdog and absolutely worth our consideration today.
