When we talk about park adjusted stats, and park factors, what does all of that mean? How do we arrive at those numbers and how do we account for changes over time? We also talk about “pitch design” and how that combines analytical data and player development.
We talk with Jonathan Judge (https://twitter.com/bachlaw) and Rob McQuown (https://twitter.com/Robmcquown), who oversee Baseball Prospectus’ PECOTA projections (https://legacy.baseballprospectus.com/fantasy/dc/) to get some more insight into how the projections are made, what’s new this year, and of course hip hop.

Stolen Signs is back. Harry and Kendall talk about the slow offseason, collusion and ideas on how to change the economics of baseball. After a short break (14:05) they discuss new research by Duke University that looks into neurological and motor skills and how they translate to baseball production, a new smart baseball that can provide some pitch tracking and tease some new work by the stats team at Baseball Prospectus. To wrap up (32:00), a look into the state of pitching and try to talk about what an inning(s) eater is and also what an ace is.

We talk with Ben Lindbergh and Kaz Yamazaki about the NPB posting system, differences between the mounds, balls, culture of MLB and NPB and dig a little deeper into some of the myths about Japanese pitchers coming over to MLB. We also look into the current state of the sabermetric community in Japan.

With all the recent discussion about Wins Above Replacement statistics, we wanted to get people who create and maintain the statistics together to talk about how their respective stats are created and calculated. We talk about what replacement level is, positional adjustments, how to accurately portray confidence in the precision of the statistic.
Harry and Kendall look back at the World Series, discuss the Cy Young awards and the BBWAA vote has lined up with BP’s pitching metrics over the past few years.
Next up is a preview of some new pitching statistics that the Baseball Prospectus stats team is working on and why that’s proven to be a challenge. Harry gives a look into how these statistics are imagined, designed, tested, and tweaked throughout the process.
This week Harry and Kendall talk to Jarrett Seidler from the Baseball Prospectus Prospects team about the cyclical nature of baseball in general, and analytics specifically.
Harry and Kendall also take a closer look at how pitchers end up in the bullpen and examine their route to get there. For this exercise they looked at pitchers with a debut season of > 20 IP as a reliever, and fewer starter innings than reliever innings in that year and then went on to log > 75 IP as a starter in a subsequent season, with fewer reliever than starting innings.

We start by talking about projection systems in general, then dive into 2017 PECOTA team projections. We look to see how adding in actual playing time affects the team totals. Then we talk about individual players that out-performed and under-performed their PECOTA projections.
This Week I Learned:
* Harry learns that “bullpenning” is a thing, sort of, maybe, kind of. (h/t Matt Trueblood (http://www.baseballprospectus.com/article.php?articleid=32960))
* Kendall learns to make adjustments in parenting, just like hitters like Mike Trout have had to make adjustments to high fastballs. (h/t to Jeff Sullivan (https://www.fangraphs.com/blogs/the-history-of-the-adjustment-to-mike-trout/))
We sat down with Rob Arthur, Ben Diamond, Greg Matthews, and Travis Sawchik to talk about the MLB playoffs. We touched on playoff formats (past, present, and future?) and then moved on to talk about roster construction and optimization for the playoffs. After that, Harry and Kendall talk about the things they learned this week.
This week Harry and Kendall discuss pitcher similarity scores. Where did they come from? What are they? What can they be used for? And what might they evolve into.
This week Kendall learned a little about Ted Williams, and Harry learned something from Neil deGrasse Tyson.
