Introducing RosterResource’s MiLB Power Rankings Leaderboard!
RosterResource’s MiLB Power Rankings were first developed in 2015 and have been displayed on the team depth charts ever since. Given that those depth charts feature a section called “Minor Leaguers You Should Know,” it was important that I come up with a formula that would allow me to identify the players having the best statistical seasons, with age and level integral factors.
Having the rankings visible on the depth charts has been a helpful feature, but I have often been asked by readers for a link to a non-existent leaderboard. If you’ve asked me about it, I’m sure I said something to the effect of, “We don’t have one right now. It’s at the top of my wish list. Hopefully in the near future.”
Well, I’m happy to announce that the day has finally arrived. RosterResource’s MiLB Power Rankings Leaderboard is here. And, thanks to Sean Dolinar and Keaton Arneson, it is spectacular.
The RosterResource 2023 Opening Day Roster Tracker Is Here!
The offseason drama is pretty much over, which means that we’ve reached the least eventful part of the year for the most diehard baseball fans. Still, as we count down the days until the start of spring training — pitchers and catchers participating in the World Baseball Classic will report to their respective camps no later than February 13 — we can at least anticipate the remaining free agents finding a landing spot, as well as announcements of each team’s list of NRIs (non-roster invitees to big league camp). And, if we’re lucky, maybe a big trade or two will go down.
Whatever happens, our Opening Day Tracker will be continue to be updated with a list of every player who will report to a major league camp, as well as their projected roster status.
Here’s a quick primer on who will be in major league camp, what happens as rosters are pared down to 26 players, and how our tracker can help you keep up between now and Opening Day. Read the rest of this entry »
The RosterResource Pages Are Now in Offseason Mode
The RosterResource Depth Charts and Payroll pages are officially in offseason mode, meaning that all free agents have been removed from their 2022 teams and a projected 26-man roster for Opening Day 2023 is displayed. Additionally, our Free Agent Tracker, Offseason Transaction Tracker, Injury Report, and Closer Depth Chart are also live.
As roster moves occur and news is reported, each feature will be updated almost immediately. Here’s an explanation of these very important offseason features.
Roster/Depth Chart
These visual interpretations of each team’s projected roster and organizational depth are always updated to reflect the latest news around the league. It’s important to note that the offseason pages project an Opening Day roster. Once we incorporate 2023 statistical projections — you can always see the latest here and here — you will notice that certain players currently listed in the Minor League section have a significant amount of projected playing time and are expected to play an integral role during the upcoming season. The same goes for players who are on the Projected Injured List or, in the case of Fernando Tatis Jr., on the Restricted List for the first 20 games of the season. Read the rest of this entry »
2022 Positional Power Rankings: Left Field

Yesterday, we wrapped up our analysis of the league’s infielders with third base and shortstop. Today, we shift our attention to the outfield, starting in left.
This year’s group of left fielders is projected to combine for less WAR (65.7) than any other positional group, although the “Mike Trout to left” move that was discussed this spring but didn’t come to fruition — maybe next year — would have pushed them ahead of the first basemen. This shouldn’t be a shocking revelation. In last year’s write-up, Kevin Goldstein described left field as “something of an island of misfit toys” and “a bit of a dumping ground on big-league rosters.” Read the rest of this entry »
Introducing the Starting Pitcher Probables and Schedule Grid!
The Starting Pitcher Probables Grid and Schedule Grid are the latest additions to our RosterResource collection at FanGraphs. They’re also the last of the features that remained on the RosterResource website. Moving all of the content from RosterResource to FanGraphs without losing any functionality, while also making some obvious improvements, is what I’ve called “Phase 1” of this project. Special thanks to Sean Dolinar for working so hard to put all of this into action.
“Phase 2,” which will begin in the near future, will involve us taking all of the feedback and suggestions from readers and making additional upgrades to all of the RosterResource content.
I discussed our newest features on Wednesday’s episode of The RosterResource Show. Read the rest of this entry »
Introducing the RosterResource Lineup Tracker!
The Lineup Tracker is the latest addition to our RosterResource collection at FanGraphs. This newest feature is an extension of our “Projected Go-To Lineups vs RHP” on the RosterResource depth charts, allowing readers to pick up on trends by providing a regularly updated look at where every player has batted in the order and lined up defensively throughout the season. The link to this feature can be found in the RosterResource drop-down menu under “In-Season Tools”.
I’ll be explaining the Lineup Tracker in detail on today’s episode of The RosterResource Show, which will air live at 4:30 PM PT/7:30 PM ET on Twitch and the FanGraphs homepage. It will be the first topic covered.
As has been the case with the last few RosterResource additions, including the Closer Depth Chart, Transaction Tracker, and Injury Report, we have several ideas that would improve this feature once we circle back around for upgrades. We have only one remaining feature to build — the Schedule Grid/Probable Starting Pitchers — that had been part of the RosterResource website prior to joining FanGraphs. Read the rest of this entry »
