Projection Altering Hitter Injuries

I’ve had a semi-fixation on hitters playing through injuries and how the diminished production could hamper the next season’s projection. At first, I found some correlation. Then, I didn’t. One possible answer to there being no bounceback is that the injury becomes chronic and the hitter never improves. Or the dataset could be too small.

I want to dive further into the subject, but the information around injuries is sketchy at best. Most of the time, there are no usable details. The lack of an answer means that I should stop coming back to the subject but I’m stubborn.

Very.

I’m going to go through this past season’s hitters. The dive has a couple of goals. One is to create a better dataset for future reference. The second is to understand why some hitters may have struggled when creating a profile. And just maybe, I’ll find out if I can put to rest the notion that hitters who played through injuries are under projected.

Injured Hitters: Projection Adjustments

Historically, I’ve “corrected” hitter projections to my own liking and every time I’ve backtested them to the actual results, my adjustments have failed miserably. So why create more work when the end results make my final product worse? Am I a glutton for punishment? In all fairness, I’m sure a heavy dose of Dunning-Kruger is going on but I also believe there may be a sweet spot where personal scouting can come into play. Today, I’m going back to the well one more time to see if some injured hitters should have more encouraging projections because they may have played hurt.

First, I’ve always thought playing through an injury meant that the team and the player were accepting suboptimal production. Then the player could come back healthy and full productive the next season.

At What Age is a Hitter’s Projection No Longer Reliable?

I blame my podcat mate Rob Silver for today’s study. First, he stated this:

And then he said this:

Of course, players age. Some quickly. Some not as fast. While few hitters remain productive into and past their mid-30’s, I needed a simple rule on how to deal with these vets. I found one and since I need to provide content to be paid, so does the world.

Does Postseason Play Hamper Future Production?

There is no need to beat around the bush with an intro full of cliches and examples. Simply does playing in the postseason wear down a player enough to effect their next season’s production?

Simple answer: Not really.

Less simple answer: Some with hitters, not at all with pitchers.

Complex answer: Danger math.

Effect on Hitter Production From an Early Season Injury

When I wrote my article on disappointing 2019 hitters, the data diverged from expectations in one subset of hitters. Injured players dominated the list but they also saw a huge drop in their production to the tune of about 100 points of OPS. While the season-to-season OPS values are never exactly one-for-one, a 100 point dropped is huge especially since the league’s overall OPS jumped 30 points last season. I needed to dig in.

It’s going to get a little nerdy as I have to explain how I examined the data. To try to minimize the pre and post-injury production from the investigation, I only looked at players who were placed on the IL in March or April. Little if any of their production should have been before the injury. A second reason was to help project hitters who are dealing with offseason surgeries (e.g. Adalberto Mondesi). So, over the past 10 seasons, 627 hitters met these criteria.

Don’t Forget About These Injured Arms for 2020

Some of the best draft day values can be injured arms who missed all or most of the previous season, taking them off the radar of many fantasy mangers. Some of these guys will fly up draft boards with a strong spring, but others will remain afterthoughts throughout draft season. Here are 10 injured arms to keep in mind for 2020:

Lance McCullers Jr. | Tommy John surgery (Nov ’18)

By having his TJ in November of 2018, McCullers will get the extended 16-month recovery time before returning. This will give him a chance at a full season in 2020, though it’s worth noting that his MLB-high is 128.3 innings so he has to show that he can make it through a full 30 starts in the first place. His #TooEarlyMock (TEM) price was 253 on average (71st among SPs), but it will rise quite a bit with a healthy spring. McCullers is a great target for early drafters on price alone.

Why We Missed: Disappointing Hitters

It’s time for the final installment of “Why We Missed”. The breakout pitchers and hitters are done along with the disappointing pitchers so it’s time to dive into hitting busts.

To determine who disappointed, I collected the information on any hitters who saw more than a $10 decline in value from their draft-day price. I didn’t want to just use the difference in ranks because the gap from #1 to #15 could be over $10 but the difference between #250 to #300 might just be $1. I only analyzed the hitters who had a positive draft day value.

Why We Missed: Disappointing Pitchers

After looking at the pitchers and hitters who exceeded expectations, it was time to examine the players who didn’t live up to their ADP. I had a good idea this list would be loaded with pitchers who missed a ton of time and I was correct. Of the 48 pitchers featured, 39 spent time on the IL at some point last season.

To determine who disappointed, I collected the information on any pitcher who saw more than a $10 decline in value from their draft-day price. I didn’t want to just use the difference in ranks because the gap from #1 to #15 could be over $10 but the difference between #250 to #300 might just be $1.

My Final 2019 Results: It Could Have Been Worse …

… but not by much for teams I just owned …

My 2019 fantasy season did not live up to my standards with most of the struggles being self-inflicted. Here are some overarching themes I spotted with each league plus some additional points at the end.

Horrible FAAB management

I ran out of money in almost every league and spent too much FAAB on worthless assets. Looking back over the leagues, the root cause was chasing week-only plays. From my work writing “The Process”, I found out how valuable it is to grind out each week. Additionally, I ran the weekly FAAB projections here so I knew around what it would take to get each. Initially, I got the players and but dropped them a week or two later for better options with little to show for the FAAB spent

I need to set a FAAB limit for chasing week-only plays and just accept it’s fine to miss out on a few players. A week’s advantage is worth the same in week 1 or the final week. The rest of my FAAB can be used for chasing long term improvements. Some players may straddle the long-term and weekly play so the FAAB may come from both the weekly and long term pools. I need to have a plan and stick to it.

Help Needed: Hitters Who Played Through a 2019 Injury

While the 2019 season is still semi-fresh in everyone’s mind, I have one simple request. Which hitters played through an injury instead of going on the Injured List this past season?

I’ve collected the players for the past couple of seasons (2017 and 2018). It’s time to compile the 2019 list even though the effects on a projection may be limited. Here are the players I have so far.

If anyone knows of anyone I missed, please say so in the comments with a link to the source. I not looking for guess but the player or his team saying he’s hurt. Thanks for the help.
