Marlins vs Cardinals Preview, Picks
The Miami Marlins and St. Louis Cardinals wrap up their three-game series Wednesday, with the total set at 8.5 runs.
After two blowouts — St. Louis winning 7-1 in Game 1, and Miami responding with a 5-0 shutout in Game 2 — Game 3 sets up as a quieter affair.
Cal Quantrill gets the ball for Miami, bringing a 0.56 ERA in five career head-to-head outings against the Cardinals. He’s 2-0 in those appearances and continues to pitch to weak contact.
On the other side, Miles Mikolas has quietly rounded into form, going 2-1 with a 2.35 ERA over his past three starts.
This matchup fits the “Silent Sharp Unders” system, which targets games between competitive teams where totals quietly drop from open to close.
Despite each team showing recent success, sharp bettors are leaning under based on pitching form, pace, and weather — all of which favor a lower-scoring game.
