Back in January, I made some tweaks to my KATOH projection system, and have been using that updated model for the past several months. That model was unquestionably better than the previous versions, but it left me unsatisfied. While it addressed many of the flaws from previous iterations, there was still a lot of information it wasn’t taking into account.

I’ve been plugging away behind the scenes, and finally have a new version KATOH to share with the world. In what follows, you’ll find some detail on the new model, including its notable updates. I’ll be using this model in all of my prospect analysis from this point forward. Below, you’ll find a quick run-through of the notable tweaks, followed by an updated top-100 list.

Choosing projection window based on level, rather than age

In my previous model, I projected out based on a player’s age. If a player were 22, I projected him through age 28; If he were 24, I projected through age 30. This resulted in KATOH undervaluing players who were old for their level. The goal of KATOH is to predict the value a player will generate during his six-plus years of team control. By projecting a 22-year-old through age 28, KATOH failed to capture some of that value in cases where the 22-year-old was still in A-ball.

This time around, I chose my windows based on level, rather than age. I projected the next six seasons for players in Triple-A. I did the next seven for players in Double-A, eight for A-ballers, and nine for Rookie ballers.

Devised originally in response to a challenge issued by sabermetric nobleman Rob Neyer, and expanded at the request of nobody, NERD scores represent an attempt to summarize in one number (and on a scale of 0-10) the likely aesthetic appeal or watchability, for the learned fan, of a player or team or game.

In the second inning of today’s game at Fenway Park, Minnesota’s Max Kepler hit a one-hop rocket that Red Sox shortstop Xander Bogaerts couldn’t handle. After deliberation — he looked at multiple replays —- official scorer Chaz Scoggins ruled the play an E-6.

A few minutes later, MLB.com Twins beat writer Rhett Bollinger noted that StatCast had Kepler’s smash at 109 mph. That begs a question: Should exit velocity factor into official scoring decisions?

According to Scoggins, the subject has been discussed informally by scorers throughout the two leagues. Based on those conversations, the majority feel “the numbers” shouldn’t matter — an experienced official scorer is able to make an informed decision on a hard-hit ball.

While a good argument can be made for exit velocity mattering, Scoggins brought up a valid point in defending its non-use. A ball may have been hit X mph, but was the infielder playing back, or was he in on the grass with less reaction time? More goes into a scoring decision than a number can measure.

Does this mean exit velocity will never become a tool for official scorers? In my opinion, the answer is no. Eyeball judgement will remain the primary determiner, but data will influence decisions.

Cleveland at Baltimore | 13:35 ET
Kluber (129.0 IP, 78 xFIP-) vs. Worley (51.1 IP, 104 xFIP-)
Vance Worley isn’t the precise name one expects to find headlining what is allegedly the day’s most compelling game. The score produced by the author’s haphazardly calculated algorithm for this particular contest, however, has less to do with the identity of Baltimore’s starter and more with its current place in the standings. No team is perched more precariously on the knife edge of postseason qualification than the Baltimore Orioles, which club features both divisional and wild-card odds in the vicinity of 50%. For more on that, read the author’s tortuous explanation of NERD’s ongoing playoff adjustment below. For less on that, do anything else that you want.

Earlier this week, I interviewed Giants rookie right-hander Derek Law in the visiting dugout at Fenway Park. Approximately 10 feet to our right, another conversation was taking place. Johnny Cueto was shooting the breeze with Luis Tiant.

Tiant was a favorite of mine during his glory years. Law was born in 1990, eight years after the Cuban legend threw his last pitch, but he was every bit as captivated with the nearby confab.

“I’m a huge Luis Tiant fan,” Law told me. “I’d love to go over and get his autograph after this. My dad pitched for a bit and I’m big into baseball history. Tiant is one of the guys I’ve really taken a liking to.”

The windup is a big reason. Cueto essentially copied the one El Tiante artistically employed on his way to 229 wins. Not surprisingly, the youngster has asked his Giants teammate about the wiggle and turn. Read the rest of this entry »

New York NL at Miami | 19:10 ET
deGrom (102.0 IP, 81 xFIP-) vs. Fernandez (113.2 IP, 53 xFIP-)
Given where each club currently resides within this site’s playoff-odds projections, it’s probable that either the Mets or Marlins will qualify for some manner of postseason appearance. It’s improbable, on the other hand, that both will qualify. In this way, tonight’s game resembles that scene from Mad Max Beyond Thunderdome where two men enter and then only one man leaves. How it differs from that 1985 film is that, instead of taking place in a lawless, post-apocalyptic Australian hellscape, it’ll actually just be in Miami.

Los Angeles NL at St. Louis | 20:15 ET
McCarthy (16.0 IP, 59 xFIP-) vs. Wacha (109.1 IP, 96 xFIP-)
Left-hander Clayton Kershaw last pitched on June 26th. Brandon McCarthy first pitched on July 3rd. Kershaw has produced the lowest adjusted xFIP (52 xFIP-) among all qualified starters this year. McCarthy, over his three starts, has produced a nearly identical figure (59 xFIP-). Coincidence? Yes. Of course. Kershaw and McCarthy are two distinct people, often photographed in each other’s company — or near proximity, if nothing else. The have difference faces and bodies. And dreams. They likely have different dreams, too.
