MLB Probabilities for Friday
Let’s look at the morning line and see where the value lies. Here are the probabilities for today’s top games:
| Matchup | Probability |
|---|---|
| PHI @ DET | 46.5% / 53.5% |
| CHC @ CIN | 51.0% / 49.0% |
| ATL @ STL | 59.8% / 40.2% |
| ARI @ LAD | 30.9% / 69.1% |
If you’re using your trades on today’s heaviest favorite—the Los Angeles Dodgers—a winning $10 prediction nets a modest $3.86 in profit. But if you want to swing for the fences and back the slate’s heaviest underdog, the Arizona Diamondbacks, a successful $10 trade yields a handsome $21.00 return.
When I’m handicapping these games, I always look for a statistical edge. Los Angeles profiles as a massive favorite for a reason. Their offense boasts a stellar .783 team OPS with 498 total runs, easily eclipsing Arizona’s .690 OPS and 393 runs. Plus, L.A.’s pitching staff limits damage with a 3.475 team ERA compared to Arizona’s 4.260 ERA.
In another spot I’m targeting, the Atlanta Braves (-166) have a real chance to dominate the mound against the St. Louis Cardinals. Atlanta’s pitching staff holds a sharp 3.615 team ERA and a 1.24 WHIP. The Cardinals’ arms have struggled more often, logging a 4.206 ERA and a 1.34 WHIP. Those underlying numbers make the Braves a highly appealing play for our prediction markets today.
