The division previews continue with the NL East. To help with evaluations, a crude runs created per game is calculated from Musings Marcels projections for both batters and pitchers. I then average these for the core of the team. The nine position players, the five starting pitchers, and the closer. I weight the pitchers as 90% starters, 10% closer. The selection of players comes from the FanGraphs Roster Resource.
The bottom line is a Core Winning Percentage based on the RC/G of the core batters and core pitchers using the Pythagorean method. You can see the spreadsheet with the data here.
Note that the core winning percentage (CWP) is going to be high, often the core is going to be over .500. We are basically looking at the best players on the team. Don’t take that as a prediction of team winning percentage, take it as a way to compare teams in a division.
Philadelphia Phillies
- Position Player RC/G Average: 5.36
- Pitcher RC/G Average: 4.11
- Core Winning Percentage: .630
The Phillies core offense is now old. Six of the nine projected starters play the season between seasonal ages 32 and 34. The age 32 season is often a turning point, when players who can no longer cut it fall out of the majors. The Marcels build in declines for older players, so the big three of Bryce Harper, Kyle Schwarber, and Trea Turner get knocked down a bit. That’s a big reason the Phillies offensive core projects to second best in the division. The other three starters are in the middle of their prime years. There are no up an coming hitters starting.
Note that the Phillies rate as the strongest team up the middle. If the Phillies front office does need to find some more offense, it’s easier to fill in corners than up the middle.
The Phillies core pitching staff also projects to second in the division. Wheeler projects to excellent, and everyone else projects to very good. League average RC/G according to the Marcels would be 4.71 RC/G. All five Phillies starters project to below that level. The group as a whole does a great job limiting walks, which makes extra-base hits allowed less damaging.
Philadelphia stood fairly pat after winning the NL East in 2024, and that might cost them the division this season.
Atlanta Braves
- Position Player RC/G Average: 5.41
- Pitcher RC/G Average: 3.86
- Core Winning Percentage: .663
The Braves looked like world beaters going into 2024, but wound up second in the division. Injuries and off-years left them six games behind the Phillies. Often times a great team like the Braves will regress to the mean the next year, and the Marcels pick that up. They rank first in the division in project RC/G for both the batters and the pitchers.
There is also upside for the offense. Jarred Kelenic starts the season in rightfield, but Ronald Acuna Jr. is scheduled to return to the team from his ACL injury in May. He projects to be about two runs a game better than Kelenic. On top of that, the Braves sport five starting hitters in their prime or pre-prime years. That’s another reason to see upside in the offense.
The rotation looks very good, with three of the five starters projecting to below 4.00 RC/G. No other team in the division fields more than one. On top of that, Raisel Iglesias rates as the top closer. I do worry about Chris Sale given his injury history. If would be great if that was finally over.
The downside for the team is that the declines among some of the players were real. Maybe age or slight injuries caught up with them. Maybe the league figured out the right defensive placements or most effective pitches against them. The regression to the mean may need to be helped by adjustments as well.
The Braves, however, look like they have a very good chance of regaining the NL East title.
New York Mets
- Position Player RC/G Average: 5.20
- Pitcher RC/G Average: 4.52
- Core Winning Percentage: .569
The Mets signed Juan Soto, which gives them the player with the best offensive projection in the division. Early injuries, however, have somewhat limited the improvement that Soto brings to the team. Bret Baty, replacing Jeff McNeil at second base, projects to be about one run lower in RC/G. The same is true of Luis Torrens replacing Franciso Alvarez
On the pitching side, injuries to Frankie Montas and Sean Manaea cost them a bit as well. I don’t know that it makes too much difference. While putting in the injured player projections brings the Mets core offense just beyond the Braves at 5.42, they would still rank third in core winning percentage at .611, as the core pitching only drops to 4.28.
The Mets also own the lowest core RC/G up the middle, which makes it tougher to find offense in the middle of the season.
Mets fans should be excited to have Juan Soto in his prime, but don’t get your hopes up too high that this is the season the Mets win the World Series.
Washington Nationals
- Position Player RC/G Average: 4.80
- Pitcher RC/G Average: 4.89
- Core Winning Percentage: .491
I would like to think that getting rid of Patrick Corbin‘s 6.86 RC/G projection would have done more for the Nationals core. The team still comes out with a projected core winning percentage of .491. If the best players on your team can’t bring you over .500, there’s little chance of the team finishing above even.
The good news comes from the age of the batting order. This is a young team, with most of the batters yet to reach their peak age. Only a couple, however, have limited MLB experience, so the projections for most of them are probably pretty good. Dylan Crews and James Wood are the ones to watch to see if they can greatly outperform projections based on limited data.
In looking through the top prospect minor league hitters, there’s not a lot that looks helpful in 2025. The rebuild offensively is taking place slowly.
The core pitching is frankly disappointing. None of the Nationals starters project as an ace. None of them even project to a below 4 RC/G. Again, their better prospect seem a year or two away. This simply looks like another losing season in Washington.
Miami Marlins
- Position Player RC/G Average: 4.39
- Pitcher RC/G Average: 5.10
- Core Winning Percentage: .426
There are two things for Marlins fans to watch in 2025. Xavier Edwards looks like an extraordinary lead-off hitter, and Sandy Alcantara returns to the rotation after his year off due to injury. Alcantara pitched well this spring, so maybe the team owns a ace once again.
The offense is full of prime age players, but they are also inexperienced at the major league level. Inexperienced prime age players screams, “Not that good!” There is probably upside from the projections, but the Marlins need a huge upside to get them to winning. If the talent was really there, these players would have been called up sooner.
On the starting side, Connor Gillispie looks like a solid middle of the rotation guy, but overall team team sports the worst offensive and pitching core in the division. It looks like another long season for Marlins fans.
Predictions
Here is how I see the probabilities of the teams winning the division.
- Atlanta Braves 42%
- Philadelphia Phillies 38%
- New York Mets 15%
- Washington Nationals 4%
- Miami Marlins 1%
It looks like a tough battle once again between the Braves and the Phillies. With the Mets suffering a number of injuries, they may need to have another great second half to make the post season. Luckily for the top three teams, two poor teams in the division gives them the chance to rack up a lot of wins which might help get two of the runners up wild cards.
