A new Ottoneu league has recently formed with a twist – despite the deep, dynasty-like structure of the platform, our league has decided on a single rule change this year: players without MLB experience (“rookies”) are ineligible for the annual spring player auction.  Instead, rookies may only be added to rosters through an in-season free agent player auction once they have accumulated their first MLB PA or IP.  Yes, this means Luis Robert cannot be owned (48 hour auction waiting period) until he completes his first PA, most likely to come on Opening Day (3/26) against the Royals.

This one simple rule change impacts a tremendous amount of Ottoneu strategy, a discussion for which I’ll reserve a future post.  For now, the purpose of this article is to list the rookies that have at least some opportunity to debut in 2020, and estimate which of these prospects might actually have some relevant fantasy impact this season.

The table below lists 130+ prospects that could potentially make their initial MLB rookie debut in 2020.  All players with existing MLB experience (Gavin Lux, Jesus Luzardo, Dustin May) have been removed.  The three columns to the far right should be the most useful:

Prospect season is around the corner, and while various rankings, reports, and even trades will continue to influence the ebb and flow of prospect opinions, it’s helpful to lay the groundwork for establishing this year’s fantasy prospect values as early as possible.  The list below represents a very early look at the top 101 prospects in the game for fantasy leagues tailored specifically towards traditional rotisserie scoring (where AVG, ERA, and SB are better indicators than OPS, FIP, and wOBA.). For example, this list could be a resource for evaluating the value of prospects in Ottoneu Old School 5 x 5 leagues.  The top 101 prospects for sabermetrics leagues is here.

Years ago I introduced the Scorecard system, my custom prospect ranking process, and I’ve continued to use this method for scoring and ranking this crop of 2020 prospects.  In ranking these prospects I take into account the following factors:

Scouting

“Scouting” is everything that goes into evaluating the true talent of an MLB prospect.  Age, ability, stats, rankings, “makeup”, and scouting reports all play a role here.  It’s the input of information that causes you to ask about the player’s ceiling, their floor, and what might be realistic in between.  What are the risks, and how serious are they? Is this prospect regarded more for their defensive talents than offensive? What MLB players might they compare to? What is their future value expectation and how likely are they to reach it?

Taylor Trammell scouts like a tremendously athletic player, but scouting alone hasn’t yet materialized into an elite on-field player, so there are other elements to consider when ranking him among the other top prospects in the game in this context.

Scoring

“Scoring” is honestly assessing whether the prospect’s skills and talents effectively translate to the specific scoring format of your fantasy league.  It seems obvious, but I continually see fantasy owners fail to make this connection in the way they draft and value their prospects each season.  While Andrew Vaughn might be a top pick in sabermetic leagues, his value needs to be reassessed in the context of 5 x 5 leagues, for example.  In order to be more successful in building our dynasty rosters, we need to always project value within the context of our specific league, which is what this rating is designed to consider.

Royce Lewis scouts like a dream player (and #1 draft selection), but scouting alone hasn’t yet materialized into an elite on-field player, so there are other elements to consider when ranking him among the other top prospects in the game in this context.

Few aspects of fantasy baseball deviate more from the reality of major league baseball more than the speculation of prospects.  Like most aspects of market-based economics, you often have to buy early on limited information if you want to get the best return on investment before the rest of the industry influences supply and demand.  Perception is reality until prospects actually get the chance to contribute (or fail) on a major league field, and the outcome of those small but important samples can swing values wildly in short cycles.

The goal today is to identify up and coming talent well before the masses of most leagues, so here are five prospects primed to see a big increase in value in 2019.  You won’t find these prospects sitting on many Top 100 lists (yet), but you’ll want to at least keep them on your radar as they rise in the future.

Vladimir Guerrero Jr. is the best baseball prospect in the world. He’s better than most recent #1 overall prospects. He’s the best offensive prospect since at least Kris Bryant (ROY + MVP), and many would say you’d have to go back much further to Miggy or even Pujols to get a true comparison. For some scouts he possesses the seemingly impossible combination of both an 80 grade hit tool and an 80 grade power profile. His batter’s box skills have HOF lineage and yet somehow he has done nothing but exceed expectations (batting .402 in AA at age 19 helps). He already has the look and potential of an all-time great.  Best of all, Vlad, Jr. will debut in 2019.

It’s prospect season (thank goodness, as nothing else is happening).  Nearly one year ago I borrowed from the great work by Eric and Kiley here and applied some fantasy context to their overall Top 100 prospect rankings from 2018.  We’ll do something similar for 2019, but before the full frenzy of this season’s prospect rankings reaches it’s peak, I thought it prudent to review prospect perceptions from this time last year to see if we can learn anything.

From last year’s post, the same purpose applies:

The goal here is simply to each prospect’s grades and scouting reports and then translate those skills into “what could be” for fantasy context (for example where “upside” might represent an 80%+ outcome on a prospect’s potential).

For comparison, last year’s comments are at the top, followed by a value trend and general update on where things appear to be for each prospect heading into 2019.

In November I used the Prospect Scorecard to take an early look at the top 100 fantasy prospects for both Roto leagues and Ottoneu’s wOBA-heavy FanGraphs Points leagues.  In February I also added a quick fantasy spin on Eric and Kiley’s great preseason work ranking the top 100 prospects in baseball. Later this summer (July) I’ll update the top 100 for fantasy purposes, but today I want to briefly check in on a number of prospects that I think are rising (⬆) or falling (⬇) in value for various reasons in 2018.

The Japanese sensation Shohei Ohtani is finally coming to MLB (and more specifically to the Angels), and in doing so will become the trailblazer that sets a new expectation for the future of the (possible) “two-way” player.  Because salaries and injuries continue to escalate in the game, a true double threat major leaguer is still hard to imagine in baseball, but if the 23 year old Ohtani does become the first player since Babe Ruth to make a regular impact on both sides of the ball, he will change the landscape of fantasy baseball, too.

Happy Game 7 Day!

About a year ago I released my (2017) Top 50 Fantasy Prospect rankings using the Prospect Scorecard to weight a variety of important variables in the context of fantasy baseball.  Today I’m publishing an (early) expanded list of the Top 100 Fantasy Prospects for 2018 for both Ottoneu’s FanGraphs Points leagues (where wOBA is a key measure on offense) and Roto leagues (5 x 5).

A few quick notes before we begin:

• Since “Cost” is league-dependent (auction salary, keeper round, etc.), I’ve ignored it here for simplicity by keeping it constant for every prospect listed. Feel free to use the Scorecard to make changes that reflect true player costs for your league, which will impact these rankings.
• These rankings below are intended to represent the 100 most valuable prospects for fantasy leagues (depending on scoring format).
• It’s quite possible I’m missing an obvious player that should be ranked, so let me know in the comments.  We can discuss the specific rationale for player rankings in the comments, too.  Player ages are current ages.
• For a lot more prospect resources, check out the Ottoneu community.

Here are the (early) 2018 Top 100 prospects for the linear-weights-based FanGraphs Points scoring format (a good proxy for those in OBP leagues):
