Pitcher Results After 2nd Tommy John Surgery

With Jacob deGrom and Walker Buehler coming back from their second Tommy John surgery (TJS), I wanted to go back and look at how pitchers performed after going under the knife a second time. While I had high hopes this study would find some useful adjustments, the results were mixed and probably point to the pitcher being more of the same. Read the rest of this entry »


The UCL Internal Brace Surgery Non-Study

Since both Shohei Ohtani and Drew Rasmussen got an internal brace in their elbow instead of the full Tommy John surgery, I decided to see how other pitchers who got the brace performed … and the study didn’t take long. With fewer than a dozen samples, there is no study.

Using Jon Roegele’s Tommy John surgery database, the following five major league pitchers got the surgery and returned to the majors. The surgery failed with Matt Bush and he eventually needed a full Tommy John surgery.

MLB Pitchers with UCL Internal Brace Construction
Player Surgery Date Team Return Date Recovery Time (months)
Nick Anderson 10/1/2021 TB 4/1/2023 18
Zach Britton 9/8/2021 NYY 9/24/2022 13
Rich Hill 10/1/2019 LAD 7/29/2020 10
Matt Bush 9/1/2018 TEX 4/3/2021 Needed TJS
Seth Maness 8/16/2016 STL 5/13/2017 9

Again, with a sample size of just five, I’m not going to draw zero conclusions from the list.

Additionally, these four guys got the brace and never returned to the majors.

Mitch Harris 6/15/2016 STL
Yadiel Rivera 9/1/2020 TEX
Kent Emanuel 6/3/2021 HOU
Sean Doolittle 7/1/2022 WAS

No analysis from me but the information is here if anyone wants to break out their Jump-to-Conclusions mat.

 


Batter Results After Tommy John Surgery

Tommy John surgery week continues with the hitter edition. With both Riley Greene and Jasson Domínguez (Shohei Ohtani got the brace procedure) getting a Tommy John surgery, I wanted to know how their performance changed from when they were healthy, to hurt, to fixed.

Note: I’m pushing my limits on what I’d like with a sample was 26 hitters. Sometime the matched seasons doesn’t lineup thereby pushing the number even further down. I understand if someone feels the sample is too small and blows off the results.

I found the change by using a weighted change from season to season. The hitters who had the most matched plate appearance got the most weight. Read the rest of this entry »


Hitters Who Played Through a 2023 Injury

With the season over, it’s to find out how hitters performed who didn’t let an injury heal and played through the pain. Whether these hitters cause permanent damage to their bodies or pick up bad habits, they continue to underperform their projections. Besides collecting the names myself, I’ve asked for some help (article and Twitter) for this past season’s list.

I first determined the decline in an article covering 2017 to 2019 and have continued collecting names and results (2020, 2021, and 2022). Read the rest of this entry »


Wanted: Hitters Who Played Through an 2023 Injury

For the last half dozen or so seasons I’ve attempted to collect the hitters who have played through an injury this season. These banged-up guys underperformed their projection by ~20 points of OPS the next season. That works out to a 5% drop in production. What I need is help trying to collect all the possible batters while this season is still fresh in everyone’s mind. Here are the names I have so far: Read the rest of this entry »


Injured Players to Stash for Next Year in Ottoneu

Not everyone can be in the middle of a playoff race as the regular season winds down. Indeed, if you’re in a head-to-head league, three-quarters of the teams are now just watching the final four teams battle for a championship. If you’re just playing out the string in an Ottoneu league, you’ve still got an opportunity to trawl the available free agents for potential keepers for next season.

The obvious place to start would be looking for injured players who are out for the season but are on a timetable to return healthy next year. And because of the roster rules in Ottoneu, you can grab players on the 60-day IL and add them to your roster without using up a valuable roster spot. Note: some leagues have rules about getting your roster down to a legal 40 players during the offseason to prevent players from hoarding injured players. But even if you need to cut from the fringe of your roster to keep those injured players, some can be worth it.

The trick to stashing injured players is finding the right ones at the right price. It wouldn’t be a wise use of resources to roster a player at his full value, especially considering the risk present with some of these guys. The goal is to roster one of these guys below their market value so that they’re not a burden on your salary cap after the offseason salary increase and any potential arbitration raises. Depending on your league context and the status of your roster, I could see the argument for keeping one of these stashes at a higher price. Heading into the offseason with them on your roster gives you the option to keep them, trade them, or just cut them at the cut deadline.

What I wouldn’t recommend would be to try and keep pitchers who are slated to miss all of next season. That means guys like Jacob deGrom, Shane McClanahan, or Liam Hendriks. The primary reason is that they’ll get hit with two rounds of salary increases before they’re contributing to your team again, so they need to be rostered at a salary well below market value to come close to being worth it. That could end up being a hefty amount of salary tied up in a pitcher with plenty of risk involved.

To help you identify where the line is between a worthwhile and a worthless stash, I’ve compiled a list of 22 potential stashes — 11 batters and 11 pitchers — with a range of projections next season. I’ve used the ZiPS 3 Year Projections to pull projected stats for 2024 and then used the Auction Calculator to build rough market values for those projected stats. Note: those long-term ZiPS projections haven’t been updated since the start of the season and ZiPS doesn’t have an exact playing time projection anyway; that’s going to have an affect on the projected points and values.

Injured Hitters
Player 2024 Projected wOBA Projected Pts Pts/G Projected Value Roster%
Vinnie Pasquantino 0.354 776.0 5.71 $21.80 99.0%
Rhys Hoskins 0.336 699.1 5.14 $12.00 86.5%
Jose Miranda 0.335 711.8 5.16 $11.30 21.2%
Oneil Cruz 0.334 675.9 5.12 $8.80 100.0%
Austin Meadows 0.350 622.7 5.28 $4.90 30.8%
Taylor Ward 0.341 606.6 4.93 $2.80 83.3%
Gavin Lux 0.319 577.1 4.31 $0.50 87.8%
Jarren Duran 0.306 527.4 4.36 -$7.10 98.4%
Brendan Donovan 0.313 501.1 3.66 -$9.40 88.8%
Anthony Rizzo 0.330 525.8 4.42 -$9.80 55.1%
Anthony Rendon 0.342 415.5 5.40 -$26.00 30.8%

The big problem you’re going to run into with some of these really valuable players is that they’re already rostered in nearly every league. If you’ve got Vinnie Pasquantino or Oneil Cruz on your roster, you’re probably planning on keeping them no matter their injury status. What this table does tell us is that to really justify keeping one of these guys, their projection has to be really rosy (~.340 wOBA) or they need to be rostered at a really low salary. I’ve got Taylor Ward ($3) and Jarren Duran ($8) and Brendan Donovan ($5) rostered on one of my rebuilding teams and I’m thinking the latter two are going to end up being cut in January.

Because these 2024 projections were made at the beginning of the season, they’re not taking into consideration whatever performance occurred in this year, even if it was injury-marred. That’s why Jose Miranda rates so highly above. I do think he’s an interesting target to try and stash since he had such a promising start to his big league career and it seems like his shoulder injury sank his performance this year. I’d still be wary about taking that projection at face value, but he’s young enough that he could still have a step forward in him if he’s healthy.

Injured Pitchers
Player 2024 Projected FIP Projected Pts Pts/IP Projected Value Roster%
Edwin Díaz 2.14 573.4 9.77 $24.00 97.4%
Walker Buehler 3.49 728.4 4.94 $17.80 100.0%
Nestor Cortes 3.50 648.7 4.86 $7.90 77.6%
Drew Rasmussen 3.70 601.8 4.68 $0.30 86.2%
Frankie Montas 3.95 589.3 4.37 -$1.30 65.4%
Nick Lodolo 3.90 565.5 4.82 -$5.10 98.1%
Trevor Rogers 3.73 564.6 4.57 -$5.10 81.7%
Shane Baz 3.78 493.4 4.85 -$14.90 98.7%
Aaron Ashby 3.71 483.9 4.79 -$16.30 78.8%
Max Meyer 3.83 482.5 4.50 -$16.40 87.5%
Casey Mize 4.61 395.3 3.72 -$28.40 47.1%

Injured pitchers are even trickier to try and stash. Not only are their injuries usually more serious, it can take longer for them to return to their previous levels of performance, if they get there at all. Based on these projected values, there are just a handful of guys worth stashing, but that’s more an artifact of the playing time projection affecting the point totals. Nick Lodolo, Shane Baz, and Max Meyer all represent young pitchers who have had a taste of the big leagues who have low projected point totals above. Their per inning rates are solid enough that they could still be productive members of your roster should everything break in their favor.

Fernando Tatis Jr. & Shoulder Surgeries

D. Ross Cameron-USA TODAY Sports

I tweeted out wanting to know who had shoulder surgeries similar to Fernando Tatis Jr. and it garnered many examples and opinions on the subject.

All I wanted was the names of those who had the same or similar operations but got a lot more. With those comps, I hoped to get a range of potential outcomes. Well, I got them and whole lot more.

I know most people will already be anchored to an opinion that is probably based on already drafting or passing on Tatis in drafts or rostering him or not in a keeper league. For those with an open mind, here is what I think is the best information people gave me. Read the rest of this entry »


Help Needed: Hitters Who Played Through a 2022 Injury

So it is time for the annual article examing how hitters performed who didn’t let an injury heal and played through the pain. Whether these hitters cause permanent damage to their bodies or pick up bad habits, they continue to underperform their projections. Besides tallying the results, I have started collecting next year’s player list.

I first determined the decline in an article covering 2017 to 2019 and have continued collecting names and results (2020 and 2021). Read the rest of this entry »
