Today’s MLB slate is loaded with real chances to find an edge.

Probabilities for MLB Games on Wednesday

Matchup Probability
NYY @ DET NYY 43.4% / DET 56.6%
CHC @ NYM CHC 47.9% / NYM 52.1%
MIL @ CIN MIL 55.2% / CIN 44.8%
LAD @ MIN LAD 61.4% / MIN 38.6%
ATL @ SD ATL 55.2% / SD 44.8%

Let’s break down the math so we know exactly what we are looking at. If I place a $20 trade backing today’s heaviest favorite based on the implied probabilities—the Los Angeles Dodgers at 61.4%—I would walk away with a profit of $11.24 if they take care of business.

On the flip side, if we want to chase a bigger payout and risk that same $20 on the day’s heaviest underdog, the Minnesota Twins at 38.6%, a home upset would yield a substantial $29.60 profit. There is nothing better than hitting on a live underdog, but we always need to check the stats before locking it in.

Taking a closer look at that LAD @ MIN matchup, my handicapping shows the Dodgers are heavy favorites for a reason. At the dish, Los Angeles boasts a massive .783 team OPS, plating 419 runs this season. The Twins trail behind with a .730 OPS and 392 runs.

The real gap, however, is on the mound. The Dodgers’ pitching staff holds a stifling 3.42 team ERA and a 1.09 WHIP, keeping opposing batters off the basepaths with ease. Meanwhile, Minnesota’s staff has struggled to a 4.83 ERA and a 1.40 WHIP. Mathematically, Los Angeles holds a distinct advantage on both sides of the ball, making them a very solid key for your daily strategy.
