MLB Probabilities on Tuesday
| Matchup | Probability |
|---|---|
| LAD @ PIT | LAD 49.78% / PIT 50.22% |
| NYY @ CLE | NYY 55.22% / CLE 44.78% |
| STL @ NYM | STL 46.13% / NYM 53.87% |
| CIN @ SD | CIN 53.37% / SD 46.63% |
When I’m looking for a solid return, calculating our potential payout is step one. If you wager $20 on today’s heaviest favorite, the New York Yankees (55.22% probability), you would win $14.71 for a total payout of $34.71. Conversely, trading that same $20 on the slate’s biggest underdog, the Cleveland Guardians (44.78% probability), yields a $22.80 profit, returning a nice $42.80 total. There is truly nothing better than hitting on an underdog for a bigger payout!
Let’s dig into the numbers for that NYY @ CLE matchup. The Yankees hold clear statistical advantages across the board, which is why I’m confident in their favorite status. New York sports a strong 3.274 team ERA and a .764 OPS at the plate. Meanwhile, Cleveland trails with a 3.78 staff ERA and a much quieter .688 offensive OPS, which entirely explains their underdog status at home.
In the tightest contest of the day, LAD @ PIT, the Dodgers look incredibly appealing as a near coin-flip. Los Angeles carries an elite 3.168 pitching ERA and a robust .784 OPS, outclassing Pittsburgh’s 4.033 team ERA and .735 OPS. Despite the dead-heat probabilities, the Dodgers profile as the tangibly stronger team on paper, making them a great, sophisticated target for our bonus funds.
