Mets vs. Marlins Prediction, Winner Payout, Over/Under – Saturday, May 23

It’s been a rough start to the season for the New York Mets, who have the highest payroll in baseball this season at $334 million, per Spotrac. They are currently 22-29, half a game behind the Miami Marlins for last place in the NL East, and 13.5 games out of first place in the division. 

They have struggled with injuries this season, playing a large chunk of the season without OF Juan Soto and losing SS Francisco Lindor on April 22 to a left calf strain that will likely sideline him for a few more weeks.

The Marlins have not been much better with a 23-29 record, but their expectations coming into the season were far lower than the Mets considering they have the lowest payroll in baseball at about $79 million.

This is the fourth-youngest team in the majors, with an average age of 27.4 years, and they are about average across the three major categories. Their starting pitcher rotation ranks 19th with a 4.19 xFIP, while the bullpen ranks 17th with a 4.14 xFIP. Miami's offense is equally as average, with a wRC+ of 96 (19th).

Mets vs. Marlins Prediction on Spread – 5/23/26

Here are the key game stats and trends behind our Mets vs. Marlins prediction for the run line for Saturday, May 23.

Lock in your Mets vs. Marlins prediction on PrizePicks before the line moves.

• These two teams are incredibly evenly matched, but a few metrics suggest the Mets may be able to pull away from their division rivals in the coming weeks.
• The Marlins have a BABIP of .296, ninth-highest in the majors. The Mets have a BABIP of .272, the fourth-lowest in the majors; that could be a potential sign of impending positive regression for the hitters in New York.
• While Marlins SP Max Meyer has an xFIP about half a run better than Mets SP Freddy Peralta, Meyer could still be due for some negative regression from the long ball. Meyer has a career 17.0% HR/FB% allowed, yet his HR/FB% is just 7.4% this season.
• For all the Mets' struggles this season, their bullpen has not been a flaw. They rank fifth in the majors with a 3.73 xFIP, compared to the Marlins at 4.14 (17th).
• The Marlins have a wFA/C (fastball runs above average per 100 pitches) of -0.95. This is the worst mark in baseball and doesn’t bode well for Saturday against a hurler whose nickname is "Fastball Freddy."

Mets vs. Marlins Player Picks, Stats for PrizePicks – 5/23/26

Here are the top Mets vs. Marlins picks to target on PrizePicks for Saturday, May 23. Today’s MLB picks for PrizePicks include Freddy Peralta and Max Meyer.

Mets SP Freddy Peralta vs. Marlins: 17.5 Pitcher Outs

• Peralta has struggled with his command this season, sporting a 4.14 BB/9. That's his highest mark since his rookie season in 2018.
• This lack of command could prevent him from going deep in this game against a Marlins team that is walking 8.9% of the time this season.
• Fastball Freddy has struggled on the road this season, with a 6.19 K/9 and a 4.43 xFIP away from New York compared to a 10.10 K/9 and 3.81 xFIP in Citi Field.
• He's surpassed this projection in only three of his 10 starts (30%) this season, and none of those starts were on the road.
• The Mets only used three low-leverage arms out of their bullpen last night, so they should be rested and ready to go in case Peralta struggles early today.

Marlins SP Max Meyer vs. Mets: 16.5 Pitcher Outs

• Max Meyer is in the midst of a true breakout season and catches a dream matchup against a Mets team that struggles mightily against his best pitch.
• Meyer throws a nasty 92 mph slider that carries a 53.1% usage rate
• According to FanGraphs, the Mets have a wSL/C (slider runs above average per 100 pitches) of -1.33, by far the worst in the league by over half a run.
• Meyer, like most pitchers, has been better at home throughout his young career. He has a 2.65 FIP at home compared to 3.74 on the road this season.
• The Mets see 3.85 pitches per plate appearance this season. That is slightly below the league average of 3.88 and could create some fast outs, allowing Meyer to go deeper into the game.
