PROSPX

PROSPX is a MLB prospect/farm system evaluation and scouting module created for @eephus_io by @ARKNDJL

PROSPX also has an interactive visualization of how the 20-80 FV scouting scale works and how we're evaluating it in regards to PROSPX/MLB Pipeline/FanGraphs grades by using historical FV grades as predictive metrics for future WAR production (based on 20-80 scale distribution)

More details (Cohort outcomes by FV tier). All of this will be available in the new source comparison in the revamped Methodology/Glossary section, as well as insights into all of the metrics created for PROSPX, details into the site, and extensive methodological details.

Here's a look at head-to-head predictive accuracy (re: prospect FV grades) between PROSPX, FanGraphs, and MLB Pipeline. On the set of 4,519 players graded by all three, the PROSPX consensus edges out both. The margin is modest & not uniform year-to-year, but it's encouraging!

Here's a look at PROSPX's prospect risers! Risers (& fallers) are derived via a combination of qualitative (tool/FV based grade) and quantitative (production, statistical) changes.

The top 5:
MIL Andrew Fischer
LAD Josue De Paula
ATL Eric Hartman
CLE Cooper Ingle
TBR Theo Gillen

Here is the first edition of PROSPX's farm system rankings/grades! Rankings are calculated through a comprehensive review of a farm system's acquisitions, development, financial performance and MLB Production, using surplus value/DvM+ as main drivers. Open Beta is launching soon!

@TWEETINGREEN @ARKNDJL @eephus_io Closed Alpha is being limited to a select group of testers, but I promise the Open Beta is coming as soon as possible. I can't wait to hear your feedback then!

Samuel Basallo graduated with a 61 consensusFV grade on PROSPX, with some ludicrous tools:
73 PWR, 70 frame, 69 arm, 60 athleticism (tool dev pictured below)

I'm a big fan of Basallo's profile as a prospect & believe the Orioles made an incredible move extending Basallo early.
