Baseball is a business, and ball clubs, like Fortune 500 companies and Silicon Valley start-ups, must constantly look for ways to improve and evolve. Often this involves forward thinking: How can Bayes’ Theorem work to project a player’s on-base percentage for each of the next three seasons? How will raising ticket prices affect sales? Of course planning for the future is wise, but sometimes the most advantageous way to plot for the coming years is to analyze what was done well—or not so well—in the past.

Given the Chicago Cubs’ ongoing success built on a foundation of exciting, young, homegrown players, the concept of effective rebuilding has been a subject of much discussion in the baseball world. Analysts deem Cubs executives geniuses and front office heroes, and then try to explain how exactly Chicago’s lovable losers transformed into one of baseball’s elite in just four years.

I’ve heard a lot of talk about how the Cubs have found success through the draft—specifically by spending more to sign draft picks, sometimes ignoring budgetary constraints. I set out to investigate how teams are valuing the draft in terms of spending; specifically, I wanted to evaluate how front offices are approaching their draft allowances. Are better teams doing something differently? How has the draft spending landscape changed since 2011?

I’ll focus on the five most recent seasons—2012 to 2016—to see how teams spent their money acquiring players, developing farm systems, and ultimately building major league teams.

Process

First I created a database of all 30 teams, listing the following: Spending on free agents for every year since 2012, spending on international free agents each of those years, spending on the Rule 4 (amateur) draft, and bonus slot plus/minus. The last variable, bonus slot plus/minus, is one I want to explain, as the others are fairly self-explanatory and the bonus slot concept will be the focus of this piece.

The current Collective Bargaining Agreement was passed into baseball law in November 2011, and will remain in place until next month. One of the most influential terms of the CBA is the amateur draft bonus slot stipulation. By this provision, teams are allotted a certain amount to spend on draft picks each year, based on previous season record.

Within the first 10 rounds of the 2016 draft, for example, the Phillies were allowed to spend $9,015,000 on amateur signings, while the Cubs were designated only $2,245,100. Why such a large difference between pools for these two clubs? The slots are determined based on win-loss totals from the season before, and the Phillies didn’t win a ton of games. Additionally, the Cubs exceeded their bonus pool in every year from 2012 to 2015, for which MLB imposes penalties, as described below.

BONUS POOL PENALTIES
Amt Exceeded By Penalty
0-5% 75% tax on overage
5-10% 75% tax on overage plus loss of 1st-rounder in next year’s draft
10-15% 100% tax on overage plus loss of 1st- and 2nd-rounder in next year’s draft
15% or greater 100% tax on overage plus loss of 1st-rounder in next two drafts

Let’s look at an example. In 2014, the Chicago White Sox were allotted $9,509,700 to spend on their draft picks in rounds one through 10 This was third-most in baseball. (The White Sox had the third-worst record in the majors the previous year.) In the 2014 Rule 4 draft, they spent $9,984,600, or $474,900 over their allowance. To determine what amount the White Sox were penalized, we divide their overage ($474,900) by the money they were allotted ($9,509,700). After doing the quick math, we see that they exceeded the MLB spending guideline by 4.99 percent.

By design, this value was just under 5 percent; only $9,500 more would have increased the consequences for overspending considerably. But since they stayed within the 0-5 percent threshold listed in the table above, they had to pay only a 75% tax ($356,175) and they kept all their future draft picks. So teams can take advantage of the system in obvious ways, as the White Sox did by spending right up to the limit before they would have lost a 2015 first-rounder.

The behavior exemplified by the White Sox in 2014 is not uncommon. Since 2012, teams have gone over their allotments 70 times out of 150 opportunities, by an average of more than $258,000 (though no team has ever exceeded the 5 percent limit). The chart below shows how teams have exceeded dollar limits much more in recent drafts.

Notice the average overage in 2016; it was unprecedented. All but six teams went over their recommended allotments, a drastic increase from 2013, when only 10 teams dared to stray beyond MLB’s parameters. Indeed, average spending on the draft has risen in each of the past five years, per the line graph below. Subsequent graphs demonstrate how spending on free agents and international free agents, on the other hand, haven’t followed such a steady pattern. Free agent spending seems to be generally less predictable, while draft expenditures keep rising.

stampfl-2 stampfl-3 stampfl-4

So why does amateur draft spending continue to rise every year?

Well, maybe the franchises that refused to overspend in the early years of the CBA have started to catch on. (Or at least they think they’re catching on.) The table below shows how much each team paid above or below its respective bonus slot in the 2012 Rule 4 draft. Look closely at which organizations broke out the wallets, and which didn’t.

stampfl-5I’m certainly not pushing it when I say that, in general, more successful franchises went over their limits in this specific draft. The Cardinals, who exceeded their bonus slot by a whopping $312,890, won the NL Central every year from 2013 to 2015 and narrowly missed a Wild Card berth this year. The Blue Jays, who struggled for most of the 2000s and early 2010s, have come to life in recent years. Then, of course, we have the Cubs. Under the direction of part-time miracle-worker, part-time curse-breaker Theo Epstein, the Cubs have spent a grand total of $1.7 million over amateur draft allowances since Epstein’s arrival, the most of any organization.

On the other end of the spectrum, we have the penny-pinchers, the teams that seem to loathe spending money on the draft. The Phillies might be our prime example of undervaluing draft picks—in the first four seasons of the current CBA, Philadelphia undercut MLB’s bonus allotment by a total of $437,800. It’s no wonder they won a league-low 63 games in 2015.

Though not all of the franchise’s failures since 2011 can be plainly attributed to excessive frugality when June rolls around, it isn’t hard to notice that the Phillies have struggled mightily as they have fielded teams of mostly old, ineffective players (see: Howard, Ryan).

But the eye test is not always enough. No matter how telling it may be that the powerhouse, younger-by-the-day Cubs have made it a habit of going over their draft bonus slot while the cellar-dwelling Cincinnati Reds have done quite the opposite, we need to look at some more numbers.

I found the relationship between dollars spent in the 2012 amateur draft and Pythagorean wins in subsequent years. Pythagorean wins determines how many games a team should have won based on run differential. This statistic is widely believed to be more representative of how good a team really is than actual wins and losses, as it attempts to tease out the luck factor. The table summarizes the regression analyses I ran, with the x-variable remaining dollars spent over allotment during the 2012 Rule 4 draft and the y-variable being Pythagorean wins in a respective year after that draft.

REGRESSION ANALYSIS RESULTS
X-Variable Y-Variable R-Squared
2012 Bonus Pool +/- 2013 Pythagorean Wins 0.0199
2012 Bonus Pool +/- 2014 Pythagorean Wins 0.0747
2012 Bonus Pool +/- 2015 Pythagorean Wins 0.2174
2012 Bonus Pool +/- 2016 Pythagorean Wins 0.4857

Notice how the R-Squared values increase as years go by—this signifies that the players teams pay for in a given draft start to have a real impact three or four years later. We would expect this, as players graduate out of the minor leagues and start to contribute to the big league team a few seasons after being drafted.

But the most noteworthy of the R-Squared values comes from the 2012 Bonus Pool-2016 Pythagorean Wins relationship, for which a scatterplot with least-squares line is shown below.

Teams that overspent are on the left side of the graph. The association isn’t overly tight, but there definitely seems to be a pattern here. This would imply that there are positive effects of overspending on draft picks in order to build a stronger team a few years down the road. Sure, you will lose some money then, but with a few strong draft picks and savvy contract negotiations, a team could use those same picks to make up for the overage tax.

So we’ve reached a conclusion: Teams should be spending more on the draft. Or, rather, they realized that they should have been spending more and have since started to change. The Cubs made “rebuilding years” cool again; the Phillies are doing it now ($480,00 over budget in the 2016 draft), the Padres are doing it ($575,000 over slot), and the Tigers are giving it a try ($241,000 overage).

And the logic is there: Spend more to sign young players in the amateur draft, sign fewer expensive (and older) free agents, and, in doing so, construct a young core of players that in just a few years will take pro baseball by storm. That all sounds great.

But is it the right conclusion?

It might be. That’s not a satisfying answer, I know, but the truth is that the sample size just isn’t very large. The CBA has been in place for only five years, and there are just 30 major league teams. Also, many of the teams that favor overspending on the draft are some of the league’s richest; they tend to pay more for players of any age because they have the resources, and they usually win more games because of this.

Another reason to doubt that draft pick overspending guarantees future success can be found when looking at bonus pool plus/minus numbers for the 2013 Amateur Draft.

stampfl-7These data don’t pass the eye test, at least not as well as the 2012 data did. Sure, the Cubs remain on the overspending side, but the Houston Astros, for example, known for stockpiling young assets during a rebuilding period in the early 2010s, opted to save money in 2013. The Braves overspent considerably, and they’ve struggled in years since, while the Blue Jays spent well below their cap and have been to the ALCS in each of the last two seasons. Then again, it’s hard to even reach conclusions on this topic, as the 2013 draft was only three years ago and some of these players are still developing.

Thus, the principal idea we most likely have to consider is not how much teams are spending on the draft, but rather on whom they’re spending. This is why we can’t just look at increased Rule 4 draft spending and say that front offices are suddenly making better decisions. It might be safe to say that their intentions have improved. But the most important factor will always come down to the players they overspend on.

The concrete conclusion we can gather from all of this is that teams are opting to overspend on the draft, more so than they did in the early years of the current Collective Bargaining Agreement. The reasons for this are unknown, though I’ve come up with a few theories:

  1. Rising revenue has led to more spending overall. Combined revenue of all 30 major league teams has risen every year since 2007. This is shown on the line graph below. Armed with more money, teams tend to spend more, and that includes spending on the draft.
    stampfl-8
  2. More prep-level draft picks means higher signing bonuses and larger expenses for teams. Though Moneyball famously advocated taking college players in the draft, as Billy Beane viewed them as safer bets who are closer to the majors and thus more predictable, the early years of the current CBA saw a rise in the percentage of draft picks taken out of high school. There are a few reasons for this. High school players are younger, of course, and high school pitching prospects have less mileage on their arms. Prep players are also considered to have higher ceilings, and upside is everything to a lot of teams.But the preference for high schoolers comes with a price for major league organizations: Prep players have more leverage in signing bonus negotiations. If a team balks at paying a high school draft pick what he’s requesting, that player can opt to go play in college. A college senior boasts no such power. Thus, major league teams are forced to pay more for their draft picks as high school players invade the market.
  3. Teams have started to take advantage of what seems to be a faulty penalization system. It’s no coincidence that organizations overspend only up to that 5 percent boundary—anything more would cost them valuable selections in subsequent drafts. So as more and more teams overpay (because they have to pay only a 75% overage tax), the overall numbers will demonstrate a trend in going over budget.

The second theory is worth investigating. Is the number of prep-level draft picks still on the rise? Do these picks average more lucrative bonuses?

I studied some data (provided by Baseball Cube) on the complete history of the MLB draft since 1965. These data included round and pick number, signing bonus, and whether the player was taken out of high school or college.

I first compared average signing bonus for both categories of draft choices. This confirmed what was suspected: High school players score more lucrative bonuses than their college counterparts. Since the first amateur player draft in 1965, high school players have averaged higher signing bonuses in 41 out of 52 drafts. And college players have made less in bonus money every single year since 1992.

Once again, this is due to prep players wielding more leverage in negotiations. A recently drafted high school graduate probably has an NCAA scholarship waiting for him. He can turn down a professional contract if the wage isn’t right. But a college player? He can’t be so selective. Consequently, high school players tend to make a great deal more in signing bonus money.

In addition, there is a noticeable trend in recent years when it comes to prep and college draft picks. However, it is not the one I expected to see and probably not one that would explain why team draft expenditures are rising. In each of the past three years, the percentage of college draft picks has risen, taking us back to the Moneyball days.

stampfl-10

The divide between high school and college draft selections grows in each year from 2012 onward. This obviously does not support my theory that draft overspending is apparent due to franchises picking high school players—the more expensive options—more frequently. Teams are actually taking more college players in the era of the current CBA.

Theory 3 appears to be the most plausible, then. Teams are pushing the limits of the current Collective Bargaining Agreement’s bonus slot punishment format. There is simply not a large enough disincentive to prevent organizations from going up to that 5 percent border and then cutting themselves off before they start losing future picks.

Thus, the trend is there. Teams are increasingly disregarding MLB’s bonus slot recommendations. The questions now lie in the future: How will teams act in respect to draft bonus slots and how might the upcoming Collective Bargaining Agreement change to inflict harsher penalties for going over budget — or will it even wipe out the slot concept as a whole?

Very interesting article Billy.

For your table reflecting Bonus pool on the X axis and Pythagorean wins on the y axis w the R-squared value, perhaps using WAR of drafted players would be a better value to use for the Y-axis as it would show correlation with how much money was spent and how much WAR the drafted players had achieved? Would likely also have a higher R-squared value.

Also, knowing that college players have fewer alternatives, the reason the number of college players has increased is that when a team selects an over-slot high school player early in the draft the team knows that it will need several below-slot college players later in the draft to offset the high school player’s bonus.

Thanks Carl! Good points, I appreciate the input. You’re probably right about the y-axis, just difficult sometimes to put that data together. But WAR of drafted players would probably be more telling.

I don’t think this is necessarily a faulty penalization system, it’s just that the cap is effectively 108.75% of the listed pool size (the 5% teams are allowed to go over, plus the 75% tax on spending over 100%). That’s still a significant restriction on signing bonuses compared to where they would likely be without penalties, and no one is going over the hard cap at 105% (plus tax) of the allotted pool sizes, so the system in place is still doing exactly what it was designed to do.

Putting in another soft cap via the tax at 100% just lets them redirect some of the money spent on signing draftees back to club owners, but the hard cap at 105% is still giving MLB more or less total control over teams’ draft bonus spending.

It is interesting that more teams have started treating the hard cap as the real cap in the last year or so and that fewer teams are trying to stick to the soft cap.

Billy, great article. In your graph detailing high school picks vs. college picks, what number/percentage of those players signed? For instance, if there was a large number of high school picks that did not sign in 2012, two things might have happened: 1) there would be less spending on the draft, since they are the more expensive players, and 2) they would ultimately be selected as college players in 2015 and 2016, after they developed further in college.

The percentage that sign may be fairly constant year-to-year, but if it’s not, it might indicate that one draft year was particularly loaded and those draftees got low-ball offers. Just a thought, interested to see what you think!

Good points, Andrew. Thanks for reading! Though I’m not sure about exact numbers, I can pretty confidently guess that many more college players sign in comparison to high school players. As you know, this is because high school players have the college option. You’re right that if this proportion was especially high in 2012, it could have affected the following years.

Yeah, it’s definitely Theory 3; the teams are just gaming the system, similar to the way that the same teams figured out out how to make a killing in the IFA market by scooping up multiple high-priced IFAs in one signing period and then losing the next signing periods as a penalty.

But even though you touched on the greater leverage that high schoolers have vis-a-vis college players, you didn’t fully explain how the teams compensate for this leverage – after all, even with the highest budgets approaching $10M, a 5% overage in and of itself is only $500k – almost statistical noise when you’re trying to scrape up a couple million dollars to sign a stud 18 year old that’s committed to Vanderbilt.

By concentrating your focus on overall spending you missed a key part of the strategy, namely combining underslot signings with overslot signings. The Cubs played this to perfection in 2014. With their 1st 3 picks they took 3 “reach” picks from college: Kyle Schwarber, Jake Stinnett, and Mark Zagunis who together signed for close to $1.85M underslot. With their next 3 picks they took 3 HS pitchers: Carson Sands, Justin Steele, and Dylan Cease, paying each one of them at least $1M to forget about college. In rounds 7-10 they picked 4 more college players and paid them a combined $340,000 underslot to finish financing their overslots. Most of that $340,000 came from James Farris and Ryan Williams, two college seniors who signed for $3K and $1K respectively.

Sands and Steele slipped to the 4th and 5th round because of signing concerns. Cease (now the Cubs top pitching prospect) would have been a definite 1st rounder but was headed for TJS. By playing the under/overslot game the Cubs were able to take a chance on these HS players in the middle rounds without worrying about not signing a top pick.

If you take a look at the Cubs picks from the first 10 rounds, nobody signed for an amount within 10% of slot (either over or under), and only 3 were within 20%. The Cubs mapped out a perfect strategy for effectively ignoring the individual slot restrictions while adhering to the 5% overage limit. That’s how they gamed the system (and picked up Kyle Schwarber and Dylan Cease while they were doing it).
