When the first article on your new website spreads like wildfire, it’s both heartening and daunting at the same time.  In December 2014, we launched The Point of Pittsburgh and the first article was How Much Is An MLB Prospect Worth.  Its success made Steve and I realize we were right in that there was a large audience waiting for good analysis from TPOP.  The article has been featured in the Washington Post, virtually every MLB team’s website on SB Nation, various team message boards, and most prominently on Fangraphs across multiple articles.

But with all models, they must constantly be refined with new and revised input data to stay up-to-date.  For this update, we examined every facet of the model to see what needed tweaked.  What follows is the methodology behind the concept of surplus value and what was changed.  You can always click the link above to see the original and how things progressed.

What Is Prospect Surplus Value?

Youth is the currency of choice in Major League Baseball.  Years of control and the ability to pay a player at depressed wages, both at minimum scale and arbitration rates, is the key for a team seeking to get high value from players.  If you have some key players making little money, it can help you address other needs in free agency at inflated prices.  It’s how bottom lines are balanced.

Teams control players for six full seasons, typically with three of them at minimum salary and three at arbitration rates, which are a fraction of a player’s worth on the open market.  There are tricks that all teams employ to squeeze a little bit more than six seasons out of a player, like waiting until a few weeks pass to bring him up and thus not have the player get a full season (like Kris Bryant and the Cubs) or waiting until the Super 2 deadline passes in late June to avoid paying arbitration four times (like the Pirates and other teams with virtually all their top prospects).

So if a team is assessing how much a prospect is worth when discussing him in a trade, they have to calculate what value that player may contribute to the team for his six seasons of control in the future.  Teams are employing some type of financial analysis to do this.  At TPOP, we did ours on a present worth value model where future values over a period of time are shunted forward to present-day in one lump sum.  The player’s potential earnings are then subtracted from the present worth number to obtain surplus value, or the amount of value that a team places on that asset when discussing him in potential trades.

What Is The Source Data?

Since 1990, Baseball America has been ranking the Top 100 prospects across baseball.  I have always viewed Baseball America as being very middle-of-the-road in their analysis, in comparison to other sites that skewed too heavy in potential and tools.  Plus, they’ve been doing it longer than other places, so there’s more of a body of work to draw from.

The initial iteration of this article mined the data from the 1994 to 2005 Top 100 prospect lists and put the players into different tiers for analysis, based on being either a hitter or a pitcher and their rankings.  Since a shade over a year has passed, we included the 2006 Top 100 prospects, too.  The thinking is that a player on the 2006 list probably graduated from the minors no later than 2009, then spent 2010-2015 accruing their six full seasons with their team, thus giving us the proper amount of WAR they generated for their team(s) while under team control.

How Was Player Value Calculated?

We used Fangraphs for the Wins Above Replacement (WAR) generated by a player during their six seasons under team control.  Allowances were made for the partial seasons that teams got by calling players up later in the season.

How Was Player Worth Calculated?

It has been assumed through the analysis of free agent contracts that the cost to purchase 1 WAR on the free agent market is now around $8M.  The initial article used a figure of $6.5M/WAR, so this has been modified to fit the new figures.  So the player’s six (plus) years of team control WAR were added up, multiplied by $8M/WAR, then brought to present value with a discount value of 8%.  I briefly toyed with lowering the discount value (the compound interest from year to year), but ultimately decided against it because of the new Collective Bargaining Agreement on the horizon.  I think with all the money currently in the game, player salaries are going to be escalated through the new CBA, thus increasing the cost per WAR.

How Were Player Values and Costs Distributed Over 6 Years?

Originally, we made the non-quantified observation that approximately 2/3 of a player’s value was achieved in the arbitration years of team control.  Now after re-assessing the data, we have scaled that figure back to 3/5 during arbitration.  Additionally, we crunched the numbers on player contracts that went through arbitration in last week’s article and came up with arbitration values of 25/40/60% for the three arbitration years.  This averages out to 42%, rather than the 60% we previously assumed with the 40/60/80 model.

So Surplus Value Is…

The present worth value calculation minus the amount of potential salary that a team has to expend over the three minimum salary years ($1.6M) plus three arbitration years (3/5 of present value WAR x 42% x $8M per WAR).  The results for the hitters and pitchers, broken down by the various tiers, are shown below:

Tier Number of Players Avg. WAR Surplus Value % Less than 3 WAR % Zero WAR or less
Hitters #1-10 54 15.3 $73.5M 12.96% 7.41%
Hitters #11-25 42 13.0 $62.0M 26.19% 7.14%
Hitters #26-50 89 8.1 $38.2M 47.19% 29.21%
Hitters #51-75 102 4.9 $22.4M 56.86% 46.08%
Hitters #76-100 102 4.5 $20.6M 63.73% 39.22%
Pitchers #1-10 22 14.6 $69.9M 4.55% 0%
Pitchers #11-25 43 8.3 $39.0M 44.19% 27.91%
Pitchers #26-50 85 6.4 $29.8M 41.18% 23.53%
Pitchers #51-75 104 3.7 $16.5M 69.23% 44.23%
Pitchers #76-100 113 3.5 $15.6M 65.49% 43.36%

As with the original article, the best bets for prospects still remain the elite #1-10 hitters and pitchers.  It amazes me with all the volatility around pitchers, due to potential injuries and ineffectiveness, that pitchers #1-10 have the lowest bust rates of all tiers.  You know that you’re at least getting a bullpen-caliber guy (less than 3 WAR) and a pitcher won’t outright bust (Jesse Foppert came oh so close with 0.1 WAR).

There also remains little difference between both hitters #51-75 and #76-100, as well as pitchers #51-75 and #76-100.  Again, moving forward at TPOP, we’ll lump both groups in as #51-100 prospects within their respective hitter/pitcher groups when discussing surplus values.

The hitters #11-25 and #26-50 raised their average WAR totals up slightly due to the influx of the outstanding 2005 1st round draft picks.  Ryan Zimmerman, Alex Gordon, and Troy Tulowitzki all raised up the #11-25 tier (with their placements reflecting their advanced college nature), while Cameron Maybin, Ryan Braun, and Andrew McCutchen bolstered the #26-50 tier.  It’s a little surprising that Braun wasn’t up higher, but there were always concerns about his ultimate defensive position, which may have hampered his ranking.

Here’s a comparison between the 2015 Surplus Values and this article’s 2016 Surplus Values:

Tier 2016 Surplus Value 2015 Surplus Value
Hitters #1-10 $73.5M $48.4M
Hitters #11-25 $62.0M $38.3M
Hitters #26-50 $38.2M $20.3M
Hitters #51-75 $22.4M $14.5M
Hitters #76-100 $20.6M $11.6M
Pitchers #1-10 $69.9M $40.4M
Pitchers #11-25 $39.0M $24.5M
Pitchers #26-50 $29.8M $18.7M
Pitchers #51-75 $16.5M $9.4M
Pitchers #76-100 $15.6M $9.6M

But the big takeaway from all this is how the value of prospects of any ilk has increased, due to the rising market costs to acquire talent in free agency and how little these players are paid in relation to free agency prices.  This is why teams are so reticent in recent years to part with high-end talent, even in light of the shockingly high bust rates shown in the last two columns of the table for certain tiers.  If a player hits, it’s a goldmine for the team.

Baseball America unveiled their 2016 Top 100 prospects list a few days ago.  Four Pirates made the list at the follows positions and their corresponding surplus values:

  • Tyler Glasnow — #14 ($39.0M)
  • Austin Meadows — #22 ($62.0M)
  • Josh Bell — #38 ($38.2M)
  • Harold Ramirez — #95 ($20.6M)

Even though Glasnow is universally regarded as the #1 prospect in the system, Meadows is actually the more valuable prospect due to the volatility of pitchers in the #11-25 tier and the reliability of production from hitters in the #11-25 tier.

Josh Bell has nearly equal value as Glasnow, with the hitter #26-50 having nearly the same bust rates as Glasnow’s pitcher #11-25 tier, but Bell’s bust rates are double Meadows’s chances to accumulate 3 WAR and quadruple his rate to accumulate zero or fewer WAR.

Not just for Pirates but for all players, it’s important to trendline how a prospect is moving through the course of these lists from year-to-year.  If a player is sliding down, by all means consider moving him, especially any player ranked in the back half of the list.  This year, Taillon dropped off the list from #29 in 2015, but that’s what happens when you don’t competitively pitch for two years.  Reese McGuire also dropped off from #97, which happens when you can’t even hit for a 600 OPS, no matter how great of defensive abilities his supporters trumpet that he has.

In the end, all prospects are lottery tickets.  Our work merely shows that some have better chances of “hitting the lottery” than others.

  1. This is good work, guys, but the end result showing Meadows as 1.5x more valuable than Glasnow (and Bell basically equal to Glasnow) should be a red flag rather than a conclusion. Few teams (if any) would trade Glasnow for Meadows straight up, and few (if any) would ask for Meadows over Glasnow in a trade for a veteran. perhaps Meadows is more valuable in some abstract sense, but if you are trying to model the actual market for prospects Meadows>Glasnow should tell you that the model is wonky.

    Not that there is necessarily anything to be done about that. My takeaway would be more about taking the results with a huge grain of salt. For instance, not basing trade proposals on them as if evening out the values makes a trade fair.

    But if you wanted to, you could do a follow-up where, instead of using tiers, you treat each ranking (#1, #2, #3, etc.) independently and use a best-fit line to smooth out the inconsistencies in the final results. You could still separate pitchers and position players if you want. Not sure if this method would be better, necessarily, but it would at least allow you to acknowledge that Glasnow, for instance, is a more highly-rated prospect than Meadows, instead of assuming they are equal other than the pitcher-hitter difference.

      Thank you for the good words. Steve and I didn’t dictate the model to say that Meadows should/should not be worth more than Glasnow. The historical data back to 1994 simply said that hitters #11-25 have been more valuable than pitchers #11-25. It’s not up to us to determine if the model works or not — the data is the data and how teams choose to interpret it is up to them. I would disagree that few teams would take Meadows over Glasnow. Pitchers, as you know, are prone to injuries. There’s no guarantee that Glasnow is a starter long-term (I think he is, of course), whereas the floor for Meadows seems higher.

      Maybe the issue is that Glasnow is so close to the #1-10 tier that if he were just 2 spots higher, this discussion would be moot. But I think his BB/9 rate and lack of a plus 3rd pitch would preclude that for now. I think BA has also been burned too many times in the past by can’t-miss pitching prospects missing, too, so they don’t put too many in the top 10.

      I’m not I understand your last paragraph about treating rankings independently.
