What are your Marlins vs. Diamondbacks series predictions?

[Ely Sussman]

SuperSubs, comment below with your Prediction Time picks:

1. How many games will the Marlins win in this series? (three-game series)
2. Who will be the Series MVP? (determined by win probability added)

Once again in 2026, I will be monitoring Miami Marlins predictions from our valued SuperSubs, Fish On First staffers and livestream guests. Individual article pages like this one will be created prior to every Marlins series and featured prominently on the FOF site. Consistent participation is key if you want to win this annual contest. Submissions only take a few seconds.

 

Scoring system

A "perfect" series is worth three points:

• Earn one point for predicting which team will win the upcoming series
• Earn one point for predicting the precise number of victories for each team
• Earn one point for predicting the “Series MVP” who accumulated the highest win probability added (WPA) during the series as calculated by FanGraphs (could pick a player from either team)

FOF SuperSub Nicholas Milton and FOF staffer Jeremiah Geiger are currently tied atop the 2026 season leaderboard, which will be updated between every Marlins series. 

If you are a SuperSub, leave a comment with your Prediction Time picks on this page, or join the Marlins Discord Server and submit there. We'll feature them on the upcoming Fish On First LIVE episode and track your points throughout the season! Any picks submitted prior to the first pitch of the series opener will be counted.
