Winning Probabilities for the Mets and Phillies

Let's look at the morning line—or in this case, the full-game moneylines. If you trade $10 on the hometown Philadelphia Phillies, a winning position nets you about $8.13 in profit, handing you an $18.13 total payout. On the flip side, if you are chasing a bigger payout and drop a $10 trade on the underdog New York Mets, you are looking at $12.27 in pure profit, returning a total of $22.27 if they pull off the road upset.

Here is how I am handicapping this one: the season trajectories tell the real story. The Phillies are stepping up to the plate as a rock-solid home favorite, backed by a 54-43 overall record. The Mets, however, have been scuffling through a rough campaign, sitting at 40-57. While we don't have deeper betting trends in front of us right now—like specific situational splits or recent moneyline records—the baseline stats heavily favor the home squad. That 55.1% win probability for Philadelphia is hard to argue against.

Keep in mind that you can trade on much more than just the result of the game. For example, predict the number of strikeouts from Aaron Nola or a home run from Juan Soto.
