@PitcherList @PitcherListPLV @PitcherList it’s really blown up! Love to see it.

Hey y'all, I need to chat about our new @PitcherListPLV account. First of all, we have no idea how this happened. We expected to do a small launch and ramp it up throughout the spring as we ensured everything was working correctly, and in no world did we anticipate climbing from 800 followers to 100k+ in 24 hours. We've reached out to colleagues trying to grasp it, and I don't think anyone in their right mind actually believes I'd purchase bots to pump the numbers (if I actually wanted to, we'd do it for our YouTube channel!). While inspecting some of the cards during the day, we saw many complaining about the model's grades, and we 100% agree. Something was wrong. How on Earth could Tolle have such a low stuff grade? Triple F for Bergert's outing?! Let me explain what happened and a little more about what Pitcher List Stats is and our PLV model. We began developing PLV (Pitch Level Value) in 2019, after four years of work, and launched it in 2023. I personally worked with some brilliant people to get it to the finish line, including Colin Charles, Jeffrey Nicholas, Zach Dobroff, Cameron Grove of Pitching Bot, and now the head of our analytics department Kyle Bland. You can read the award-winning article from 2023 here:  pitcherlist.com/what-is-plv-an… As outlined there, this model is not something whipped up by AI over the last month. It takes into account dozens of factors, from release height, arm angle, movement, velocity, spin rates, extension, and all the good stuff. We've made adjustments here and there over the years and will continue to improve it indefinitely. It's a foundational metric that allows us to assess player skills on a different level, including crafting our Process+ metric for hitters. "But then why was it so obviously wrong yesterday?" Well, that has to do with a few factors, and Kyle does a fantastic job outlining what went wrong in the tweet below. In short, some overfitting, some small sample problems, and some spring training being spring training. The next tweet you'll see from @PitcherlistPLV will showcase the fixed model vs. some of the cards you saw yesterday. We're also expediting an article on the Pitcher List site from Kyle outlining all the factors that go into determining the grades you see on these cards, making it the clear reference point for everyone to use these cards to the best of their ability. Remember, we didn't expect for this account to get so much attention so quickly! Once we have our article live on our website, we will add a link inside these cards so everyone can understand the massive undertaking of making them. We spent weeks iterating on this design and determining what should go where (no AI involved), and we're incredibly thankful to have so many provide feedback on what metrics they want to see, what needs more clarity, and special requests. Please continue to do so, respectfully, of course. We've already made some changes that you'll see later today, such as renaming "Start" and "Models" to "Results" and "Skills", as they better represent what those grades are for. We love the idea of a "Start" grade to quickly grasp if a pitcher was good or poor, but we didn't make clear this grade was our version of a Game Score, and not a grade of the pitcher's stuff or PLV. We still like the idea of an all-encompassing "Skills & Results" number (and one for a SP vs. RP) and we'll keep toying with the idea. And yes, those "Start/Results" grades are low because we intended these cards to be featured mainly during the regular season, when pitchers are properly stretched out and aren't leaving after a few frames. Another artifact of our unexpected attention during the start of spring training. Lastly, while these cards are currently only for pitchers, we've already begun the process of creating cards for hitters - it's a little trickier given the small sample of a single game. I hope this post has cleared the air. We're still blown away at the support for our new account and we're excited to share our love for the game with all of you. Aces gonna ace, -Nick

@RozayRolle @Feeezy Don’t do this

@Feeezy @JakeWarshawsky Thoughts on tonight’s massacre?

@RozayRolle @JakeWarshawsky their odds definitely got better after the trade

@RozayRolle 🤣🤣

Nets look like the title favorites after that trade

@JoshShapiroPA But first @JusticeForEllen

Legalize marijuana. Expunge records.

@OldBayAddict @JoriEpstein @OldBayAddict you don’t know shit about fuck

Cowboys LB Micah Parsons on 49er playing bully ball: "I’m from Harrisburg. Where the bully gets bullied. "I ain’t never back down from a challenge."

@Zspitz12 I’d double like this tweet if I could

If you think we should do anything besides draft 3 defensive players in the first round you are an absolute moron.

@Feeezy Smh lmao

He’s not wro.. 😂😂😂

@Sam_UL_ @JoeyWendle Manifest it

@JusticeForEllen @JoshShapiroPA @KFCBarstool here too please.

All - @JoshShapiroPA just announced that he is running for Governor of Pennsylvania. Josh is the only person with the authority to reopen Ellen's case. He has repeatedly refused to do so. Please be sure to let him know how this will impact his run for Governor! #JusticeForEllen

@DanWarshawsky @JoshShapiroPA @KFCBarstool can we get a retweet here with your support? This guy can’t be re-elected in PA.

You vote for @JoshShapiroPA you’re voting for someone who plays a leading role in covering up a murder. Idc what side of politics you’re on, don’t vote for a despicable human.

@MikeSkulsky Top 3

Will never forget stopping in Danbury with @JakeWarshawsky and thinking it was the worst town in the world lmao.

The Danbury Trashers documentary on Neflix is awesome

@Matt_Maisel @fox43 @CommCharterAcad Great piece @Matt_Maisel. And great to see some of my old teachers!

Speaking of teachers, so much is being asked of them going into another pandemic school year. ICYMI - check this week's #FamilyFirst w/ @FOX43 where I sat down with a group of local educators about their concerns/challenges fox43.com/article/life/f… @CommCharterAcad

Tremendous story from @BGallagherTV about *why* teachers are so important. Many, like Dr. Hart, recognize educating in today's climate means going above and beyond what's already being asked. fox43.com/article/news/e… via @fox43

@MikeSkulsky Always comes back to Desi when we do this

@JakeWarshawsky Desi Relaford

@BrianMIBlock @JSalisburyNBCS He’s the worst manager in baseball. If it seems that way, it’s because it’s true.

Another blown save by the Phillies

@Feeezy Ben was clearly the biggest problem on the floor but you can’t say that. Not as the head coach. I agree with you they both should go.

They threw Ben under the bus but he’s also never been held accountable. I can’t see Ben or Doc back next year

@JFMcMullen @Feeezy They lost as a team. Everyone contributed. Sadly you wouldn’t know that from the post game pressers.

Embiid had 8 of #Sixers’ 17 turnovers, the less said about Simmons offensively the better and Harris was 8 of 24. How do you win when stars can’t produce late? The answer is you don’t. #Sixers
