Prospect Variance and Blocking Catchers

The Winter Conferences at all times function trades, however two stood above the fray final week. First, the Guardians traded Andrés Giménez to the Blue Jays in a two-part transaction that briefly left Cleveland with three lefty-hitting first basemen. Then the White Sox traded Garrett Crochet to the Crimson Sox for 4 prospects. The perfect of that group, Kyle Teel, occurs to play catcher, the identical place as Chicago’s prime prospect Edgar Quero. They even have the identical future worth grade of fifty, which is the cutoff for prime 100 prospects.

The Guardians made an additional commerce to keep away from doubling up on related archetypes, sending Spencer Horwitz to the Pirates for 3 younger pitchers, however the White Sox simply saved each catchers. I heard numerous murmured questioning of that call as I walked across the Dallas lodge that briefly hosted the middle of the baseball universe. However I believe each groups had been appearing rationally, and that worrying about Teel and Quero overlapping is foolish. I can’t show it for you – however I did give you some information that can hopefully sway your opinion.

Cleveland’s case was easy. Steamer initiatives Horwitz as a 2.5 WAR/600 PA participant. It initiatives Kyle Manzardo as a 1.8 WAR/600 PA participant. Josh Naylor? Steamer has him down for two.4 WAR/600 PA. Three gamers for 2 positions — first and DH. (Sure, Horwitz has performed second base, too, however he actually shouldn’t be a second baseman, and I don’t assume the Guardians would’ve used him there.) Considered one of them would experience the bench regardless of being an above-average contributor, a poor choice for a workforce that’s making an attempt to maximise its sources. One thing needed to give.

Alternatively, there are the White Sox. They, too, traded a younger star, and the perfect participant they received again performs a place the place they already had an identical choice. Teel was our 42th-ranked prospect on our up to date Prime 100 listing in 2024, a cultured all-around catcher who we count on to achieve the majors sooner or later within the subsequent two years. Quero was our Fortieth-ranked prospect, and also you’re by no means going to imagine this, however he’s a cultured all-around catcher who we count on to achieve the majors sooner or later within the subsequent two years.

What makes these two conditions completely different? Time. These three two-win first basemen? That’s what they’re proper now. All three can’t play within the majors on the similar time, although, which implies that one is obstructing out the present-day worth of the opposite. Provided that the Guardians are targeted on making the playoffs in 2025, that doesn’t actually work. Alternatively, Teel and Quero aren’t priceless to the White Sox due to what they’ll do in 2025; for them, it’s extra concerning the future.

Whenever you hear “Prime 100 Prospect,” don’t take that as a ultimate proclamation on what a participant might be. For instance, our 2019 Prime 100 listing had a delightfully various midsection:

Your future worth isn’t any assure of the place you’ll find yourself. There are tons of uncertainty. You may consider a 50-FV prospect as extra of a distribution of potential future outcomes:

You may quibble over what precisely this implies. Are our estimates imperfect? Positively. Do gamers enhance or worsen in unpredictable methods? Completely. Is that this randomness? Destiny? Unforeseeable exhausting work and confidence? One thing deterministic that we merely don’t have the instruments to detect but? I don’t have a solution for you. The purpose is that whereas the label we’re placing on each White Sox catchers now is identical, what they’ll really flip into as main leaguers is way from sure.

That’s all pretty apparent, however the magnitude issues. If the unfold of outcomes is slim, if most prospects much like Teel and Quero flip into broadly related main leaguers, possibly worrying about them blocking one another is affordable. If the unfold is extensive, or if the more than likely end result is failure, that’s much less clear. Estimating that distribution of outcomes isn’t straightforward, however it’s actually doable.

I made a number of assumptions to get a tough concept of how this seems to be in actual life. First, I assumed that the White Sox are attempting to compete three years from now – I needed to choose a quantity, and that one felt like an affordable center estimate. Subsequent, I made a decision that I’d take a look at projected WAR per 600 plate appearances as an estimator. Lastly, I needed to choose a pattern of real-life gamers to make use of as comparisons. I used all of the place gamers with 50-FV grades on our Prime 100 prospect listing in a given yr.

I wished to keep away from having the info overly corrupted by the dearth of a 2020 minor league season, so I settled on utilizing three years: prospects from 2019 projected for 2022, prospects from 2021 projected for 2024, and prospects from 2022 projected for this upcoming season. In plain English, I took our prospect lists and checked out how the gamers who got a 50 FV developed over the next three years. I used projections reasonably than outcomes as a result of not all of those gamers received full taking part in time, so small-sample variance would swamp the outcomes in any other case. Equally, I made a decision to not restrict my pattern to catchers with 50-FV rankings as a result of there merely weren’t sufficient of them.

I selected to exclude pitchers from this examine. I’d need to make assumptions about what number of innings equate to 600 plate appearances, they usually don’t appear clearly corresponding to hitting prospects, so I’m protecting the 2 separate. That also gave me 158 observations, lots sufficient for my functions right here.

My first statement: There’s an actual probability of failure; 33 of the 158 hitters with a 50 FV had been projected for 0.5 or fewer WAR per 600 plate appearances three years later. A few of these guys by no means made the majors. Some did and underperformed. Roughly 20% of the time, in different phrases, your stable hitting prospect by no means materializes into somebody you possibly can depend on.

One other 20% of the prospects (34 out of 158) had been projected for between 0.5 and 1.5 WAR per 600 plate appearances three years later. That’s a pleasant rotational participant, roughly; 2.0 WAR per 600 PA is the league common. Talking of that, one other 40% (64 out of 158) projected for between 1.5 and three.0 WAR three years down the highway. That’s the most important inhabitants, and in addition the central end result. Loads of stable prospects turn into stable gamers, nothing roughly.

The highest finish is extra diffuse. There are 21 gamers between 3.0 and 4.0 WAR, 5 within the 4.0-5.0 vary, after which Gunnar Henderson alone on the prime, projected for practically 6.5 WAR per 600 PA in 2025. Listed below are the info I used, in a really stripped-down model, for those who really feel like taking part in alongside at house.

Let’s strive that chart once more, this time with some odds on it:

Now that we have now a distribution, we will take into consideration what the White Sox are doing a bit of extra clearly. Any particular person 50-FV prospect has a 17% probability (on this information set, not less than) of ending up as a participant projected for greater than 3.0 WAR three years down the highway. However when you have two prospects taking part in the identical place, there’s a one-in-three probability (31%) of growing an All-Star-caliber choice, assuming their improvement is, broadly talking, unbiased.

Whenever you put it that approach, what the White Sox are doing makes extra sense. Having a 31% probability of growing a catcher who’s a borderline All-Star or higher sounds quite a bit higher than a 17% probability. Even higher, the chance of destroy decreases considerably when you could have two catchers as an alternative of 1. Think about the Padres and Rays. They’re good groups, frequent playoff contenders with loads of star-level performers. And but, during the last three years, they’re twenty third and twenty fourth in catcher WAR.

That unquestionably hurts their skill to compete within the playoffs – every are principally taking part in a roster spot quick in comparison with their opponents. And what are they alleged to do about it? Good catchers are exhausting to accumulate. You may’t simply transfer somebody over from an identical defensive place. The perfect ones principally don’t make it to free company. In the event you begin with a nasty state of affairs, and may’t by some means persuade the Braves and A’s to ship you William Contreras for nearly nothing (hello Milwaukee!), you’re out of luck.

With one prime catching prospect, the info recommend that the White Sox could be a nasty end result – a backup or full washout – roughly 43% of the time. Think about exiting a rebuild that took you half a decade and resulted in some completely depressing groups, solely to have your new contender hamstrung by an absence of choices at catcher. The percentages of that taking place dip to 18% for those who as an alternative have two 50-FV catchers to develop. So let’s take a look at our chart one final time, this time with the results of two 50-FV prospects on the similar place:

Nobody needs to plan on failure. It will be nice if each prospect panned out. However that simply can’t occur – it’s not even mathematically potential. There are solely so many wins to go round. Hoping your guys pan out isn’t an excellent team-building technique; it’s vital to have backup plans and redundancy. Risky gamers at far-away timelines are dangerous, and I don’t see something fallacious with managing that threat by concentrating on an thrilling prospect like Teel.

Perhaps I’m preaching to the choir on this one. It feels fairly easy to me: Prospects fail, so there’s nothing fallacious with having extras for those who’re not making an attempt to place them in your main league roster proper this minute. However the idea of blocking is overused amongst prospects. Getting good gamers is a good concept. The place they play issues lower than how good they’re, and doubling up could be priceless for those who’re making an attempt to keep away from leaving a gap in your roster. Variance is actual – the nice groups account for it of their decision-making.
