The season is heading into two different trajectories for both clubs, but tonight will be a fun battle with two of the game’s best on the mound.
Additionally, we have a classic NL East rivalry in store as the New York Mets will host the Philadelphia Phillies. Elsewhere in the division, the Atlanta Braves have an interesting battle tonight as they’ll face the impressive Chicago Cubs and Shota Imanaga.
Later, our betting model touts a five-star play on the Colorado Rockies‘ moneyline at +180 as they face the San Diego Padres. The Rockies hold the league’s longest win streak at four games, so it appears there is a ton of value with the underdog to be had tonight.
