Mining The News (4/20/20)

I’ve been sitting on a ton of possibly useful information since Spring Training was cut short. I was just going to sort through it once MLB tries to start up but it was becoming too much. I’m going to purge all the information in two to three articles and try to write Mining the News on a regular basis.

Here several quotes from several team officials and coaches on how long they think it’ll take to get pitchers ready.

• Jon Daniels says the Rangers are “idling”.

Daniels said the Rangers want their pitchers “idling their engines.” That means not shutting it down completely, but also not going at full intensity without knowing when they will be called back to work.

“Until the league tells us otherwise, we are going to try and keep guys in some sort of state of readiness,” Daniels said. “That’s going to vary with each guy based on what they can do safely. We don’t want anybody to do anything that will jeopardize their health or the public’s health.”

Sir Mike Podhorzer Asked for Questions: Here are a Few Answers

A couple of weeks back, Mike asked for possible topic ideas. Today, I’m going to go through some topics that can be quickly answered or why they may be too massive to take on. Some reasonable questions were asked that deserve their own article so don’t fret if it wasn’t answered. Also, let me know which of these topics can be expanded and how?

 

Rock Lobster: Which stats are the most volatile week to week in h2h leagues? I assume something like Ws fluctuates more from week to week than SBs, but by how much? Could knowing this information lead to any insights regarding roster construction in h2h leagues? Or is it just noise?

This is a huge undertaking. Tanner Bell compiled weekly stats for a few studies in our book, and those took months. It’s something that could be done again but what are the standard points systems used? Just the standards at ESPN, Yahoo, and CBS? Any others? It’s doable but once jumping in, I think it’ll be a one-time study so everything desired needs to be in place before it begins.

The GMs: Single Season Hitter Projections

I’ve spent the last few articles releasing new projections. Today is no different and piggybacks off Monday’s article on single-season based pitcher projections or the GM’s. Today, it’s the hitters’ turn.

While the inspiration for these projections started with Giolito, I found I wanted the same dataset available for hitters. I took the players’ 2019 stats and regressed them to the league’s average rates and added in an aging factor. Finally, I prorated everyone to 600 PA.

Brian: In dynasty leagues, how does Severino’s recent injury woes (shoulder and TJ) impact your long term outlook on him?

3:02

Jeff Zimmerman: I just assume any more that starters will miss some time with TJS. It’s why I prefer to focus on hitters long term and piece together staffs each year.

Jeff Zimmerman: With Severino (and Thor), I just don’t trust either NY medical staff to get them right

The GMs: Single Season Pitcher Projections

While I had little luck finding the next Lucas Giolito, he still intrigued me. He was possibly the worst major league starter in 2018 (6.13 ERA and 1.48 WHIP in 173 IP). Last season, he remade himself by throwing harder (avg FBv from 92.4 mph to 94.3 mph), throwing more strikes (4.7 BB/9 to 2.90 BB/9), and reworking his pitch mix (dropped the sinker and curve).

The problem is that standard projection systems still incorporate the previous three or more results which hurt his projection. Our auction calculator (Steamer) ranks him as the 45th pitcher while he’s going as the 14th pitcher in the NFBC. Fantasy owners knew to reset his projection but to what? I decided to create a projection system called the GM (Giolito – Marte) based only on the previous season results. Nothing more.

StatCast-Only Based Projections: Hitters

With the season delayed, I’ve had time to dive into some shelved projects including creating some unique projections. Today, I’m going to introduce my StatCast hitter projections.

I created the projections with inspiration from “The Model Thinker” by Scott Page.* The author states, “do not put too much faith in one model”. To further explain this stance, he states:

“The lesson should be clear: if we can construct multiple diverse, accurate models, then we can make very acurate predictions and valuations and choose good actions.

Keep in mind, these second and third models need not be better than the first model. They could be worse. If they are a little less accurate, but categorically (in the literal sense) different, they should be added to the mix. “

Finding Giolito: Richards, Manaea, & Webb

The last of the Finding Giolito series comes to pause. I couldn’t find any footage on Logan Webb and the Manaea video was crap. That said, the Garrett Richards looked great.

Garrett Richards (Padres, RHP)

Games

  • 3/3/20
  • 3/9/20

Notes

  • Pitches straight ahead attacking the plate.
  • The slider has a curveball shape but in the low 90’s.
  • He never controlled the curve in either game. He was just giving away those pitches.
  • In the third inning of the 3/9 game, he lost control of everything. He might have tried throwing his change since he bounced a couple pithces way in front of the plate.
  • While the broadcast talked of the changeup, I didn’t notice him throwing one else it was one of the pitches he bounced.

Wes: What’s your thought on fringey SVs guys in the new normal? Lugo, D. castillo, etc. Closer to SVs bc chaos or farther from SVs bc teams will trust their guys?

3:01
Jeff Zimmerman: The trade deadline might also be in play. Maybe some teams  may trade for a reliever immediately.
