The division previews begin with the NL West as the Dodgers and Cubs play two games in Japan starting Tuesday of the upcoming week. 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.
Los Angeles Dodgers
- Position Player RC/G Average: 6.04
- Pitcher RC/G Average: 3.92
- Core Winning Percentage: .703
The Dodgers look like the team to beat in the NL West once again. The offense projects to the best RC/G average in the division, and so do the pitchers. They are the strongest team up the middle offensively. There is not much they can do to be better.
Impressively, there is upside to the team. Roki Sasaki probably pitches better than the league average RC/G value given here to the rookie. Dustin May, retuning from a freak esophagus injury, might also put up better than league average number. Keeping Mookie Betts healthy all season would help, too, although he is going to miss the games in Japan due to illness.
On the downside, Freddie Freeman may have started his decline in 2024, posting his lowest rWAR in a full season since 2019. He will play 2025 at seasonal age 35. He still projects to over 7 RC/G, and only Michael Conforto projects to under 5 RC/G. Even with some aging players, Los Angeles boasts a very dangerous lineup.
The Dodgers project much better than they did at the start of 2024, and put themselves in a good position to be the first repeat World Series winner since the Yankees of the late 1990s.
San Diego Padres
- Position Player RC/G Average: 5.25
- Pitcher RC/G Average: 4.21
- Core Winning Percentage: .609
The Padres lineup is good, but lacks the big fire works of the Dodgers. Jackson Merrill and Luis Arraez project to the highest RC/G, both a bit over six runs. The three potential superstars, Xander Bogaerts, Manny Machado, and Fernando Tatis Jr., all project into the fives. If Bogaerts and Machado bounce back and Tatis reaches his potential, the Padres offense could be one of the best.
The starting pitching looks a big shaky with Joe Musgrove recovering from Tommy John surgery. Yu Darvish is showing his age leaving Michael King and Dylan Cease to carry most of the load. Closer Robert Suarez projects as the second best in the division.
This is a solid team with the potential to do very well, but right now they look more like a third place club in a tough division.
Arizona Diamondbacks
- Position Player RC/G Average: 5.28
- Pitcher RC/G Average: 4.16
- Core Winning Percentage: .617
The Diamondbacks rank ahead of the Padres in both Offensive and Pitching RC/G, and strength up the middle, making them the favorite for second place.
There are no projected superstars in the offensive lineup, but Corbin Carroll could be the one if he can keep the adjustments he put in place in the second half of the season. Ketel Marte got his stroke back in 2024, and if he doesn’t regress, the Diamondbacks offense would look much better than it does right now.
Corbin Burnes, Zac Gallen, and Merrill Kelly give the team good three man front to the rotation, and overall the core pitching in a little better than the Padres. The Diamondbacks and Padres are very close, and the division should present a good battle for second place and at least one wild card.
San Francisco Giants
- Position Player RC/G Average: 4.93
- Pitcher RC/G Average: 4.37
- Core Winning Percentage: .560
The Giants don’t have someone who might be a star in 2025. Tyler Fitzgerald projects to be their best offensive player, but he’ll be seasonal age 28 with only 375 MLB plate appearances. Matt Chapman still does a lot with his glove, but his bat isn’t what it used to be. Justin Verlander was a superstar for a long time, but even his star days might be over.
The Giants strike me as in rebuilding mode. They put a team of the field capable of competing every day, but unlikely to win enough to make the post-season. This is a year to watch what kinds of moves Buster Posey makes in the front office, and see if he can rebuild quickly.
Colorado Rockies
- Position Player RC/G Average: 4.55
- Pitcher RC/G Average: 5.72
- Core Winning Percentage: .388
A .388 core winning percentage is awful. The upside is that the batting order looks to start five players in their pre or early prime years. The bad news is that only Nolan Jones (not to be confused with The Only Nolan) projects to hit well.
The core pitching looks dreadful, with every pitcher projecting over 5 RC/G, including the closer, Tyler Kinley. Given their division opponents, a small victory for this team would be losing less than 100 games.
Predictions
Here is how I see the probabilities of the teams winning the division.
- Los Angeles Dodgers 45%
- Arizona Diamondbacks 22%
- San Diego Padres 21%
- San Francisco Giants 11%
- Colorado Rockies 1%
That probability for the Dodgers may be too low. I suspect they really want to repeat, and would likely make any in season move they feel is necessary to make that happen.
