Mets at Marlins prediction: Odds, expert picks, starting pitchers, betting trends, and stats for March 31

Its Monday, March 31 and the Mets (1-2) are in Miami, FL to take on the Marlins (3-1) in Game 1 of their series. David Peterson is slated to take the mound for New York against Cal Quantrill for Miami.

The Mets opened the season in Houston and lost two of three to the Astros. Offense was the problem for New York as they scored just five runs in the three-game set. Juan Soto, however, did homer and three hits in nine at bats for the Mets against Houston.

The Marlins played four, one-run games against the Pittsburgh Pirates to open the season…and won three of them. Miami pitching was a big part of the story as Marlins’ hurlers struck out 36 Pirates over the four games.
