    Over at FanGraphs Audio, @_Ben_Clemens is doing a really cool thing where he's interviewing FanGraphs staff to share our "how I got here" stories. It's now been 14 years since I launched MLBDepthCharts, so I had to think way back to describe how and why it all started.

    Yesterday was the 15th anniversary of the day I officially launched MLBDepthCharts, now known as RosterResource. I celebrated by spending a few hours formatting "projected lineups vs LHP" on Google Docs. TBD on how/when they'll be displayed at FanGraphs. I'll keep you posted.

    The U.S. has agreed to terms on a 4-yr deal (club option for 2025-28) with decency, compassion, empathy, science, and democracy. Hate, incompetence, corruption, dishonesty, narcissism, bigotry, and fascism have been designated for assignment in order to make room on the roster.

    Thanks to everyone who followed along here during the regular season and visited the RosterResource pages at FanGraphs. Hopefully, the content was useful. I'm on track to launch the first few MLB offseason depth charts on Tuesday (BAL, ARI, TEX, PIT).

    Cool news! My Roster Roundup will run 2x per week at FanGraphs, where I'm now a full-time employee. Very thankful to @dkappelman and excited to be working with such a talented team. I'll have more news in the near future in regards to FanGraphs/RR, but I'll say this for now ...

    Replying to @JasonRRMartinez
    Cleveland has the lowest projected payroll (est. $40M) in the game. Next lowest are the Pittsburgh Pirates (est. $47M) and Tampa Bay Rays (est. $57M). Only contract guarantees beyond 2021 are buyouts for Jose Ramirez and Roberto Perez.

    I'm planning to launch a daily "RosterResource Roundup" column that will be similar (but better) to what I was doing at FanGraphs a few years ago ... blogs.fangraphs.com/roster-roundup… Let me know if you have any suggestions for what you'd like to see in this type of column. 🧵

    Thanks to everyone who responded to this! I'm very fortunate to have turned this into a career and still be doing it 15 years later. All the words of encouragement from so many of you helped to keep me motivated early on and will continue to inspire me to create more cool things.

    New #MLB Feature Alert! Our depth charts now show Rule 5 status for all players ... rosterresource.com/mlb-depth-char… If you see "R5" in the "Options or R5 Status" column, that player is eligible for next month's Rule 5 draft if not placed on 40-man roster by the 11/20 deadline.
