Predict MLB Games on Wednesday

Here is a look at how we are handicapping today's board. I've laid out the moneylines and probabilities below so we can easily spot our best angles:

MatchupProbability
CIN @ SEASEA 58.4% / CIN 41.6%
LAD @ PHILAD 52.2% / PHI 47.8%
PIT @ NYYNYY 57.3% / PIT 42.7%
BAL @ BOSBOS 56.2% / BAL 43.8%

If we look at potential payouts, trading a standard $20 on today's heaviest favorite—the Seattle Mariners—would return a steady profit of $12.82 on a winning ticket. On the flip side, if you want a real chance at a bigger return, placing that same $20 on the slate's heaviest underdog, the Cincinnati Reds, yields a $26.00 profit if they can pull off the road upset.

When I'm handicapping the marquee LAD @ PHI matchup, Los Angeles looks like a very strong play on the moneyline at -120. We are always looking for edges, and statistically, the Dodgers hold a definitive advantage at the plate. They boast a .260 team batting average and a .771 OPS.

The Phillies have struggled to match that production, hitting just .236 with a .705 OPS overall. The pitching comparison also heavily favors the visitors; L.A. arrives with a sturdy 3.53 staff ERA and a 1.13 WHIP, numbers that easily overshadow Philadelphia's 4.22 ERA and 1.31 WHIP. We have to trust the data here!
