Sandy Alcantara’s Volume and Velocity Lead to an All-Too-Familiar Place: Surgery

Sam Navarro-USA TODAY Sports

Alas, even throwbacks get injured. For all of the excitement about the extent to which Sandy Alcantara bucked recent trends by piling up innings and pitching complete games en route to the 2022 NL Cy Young award, his combination of volume and velocity — both at the outer edge of what pitchers of recent vintage have shown they could sustain — placed him at risk for an arm injury. His season ended about a month before those of his Marlins teammates, who made it as far as the NL Wild Card Series, and on Friday the 28-year-old righty announced that he had undergone Tommy John surgery, which will sideline him for the 2024 season.

Alcantara missed just one start over the first five months of the season due to a bout of “very mild” biceps tendinitis in late April, but after throwing eight innings in his September 3 start against the Nationals, he landed on the injured list with what was initially diagnosed as a flexor strain. On September 13, Marlins manager Skip Schumaker told reporters that an MRI revealed that Alcantara had actually sprained his ulnar collateral ligament. Even so, he soon resumed a throwing program. After multiple pain-free bullpen sessions, he was allowed to make a rehab start for Triple-A Jacksonville on September 21. He threw four scoreless innings, but afterwards told the team that he felt renewed tightness in his forearm. The Marlins announced that he was being shut down for the remainder of the season.

While the Marlins hadn’t offered any indication that Alcantara’s sprain was significant enough to merit surgery, it’s not terribly surprising; after all, a sprain is a tear, and with a UCL sprain, it needn’t be a full thickness tear to require surgery. It’s unclear whether the injury worsened with that rehab outing, but the more likely explanation is that as with the Orioles and Félix Bautista, the Marlins qualifying for the postseason made it worth seeing whether Alcantara could pitch through a partial tear. The answer, sadly, was no.

Even before the initial injury, Alcantara’s season had been a significant step back from his Cy Young-winning campaign, during which he pitched to a 2.28 ERA and 2.99 FIP in a major league-high 228.2 innings while striking out 207 hitters. This year, in 184.2 innings — merely the majors’ 20th-highest total — he posted a 4.14 ERA and 4.03 FIP, though his results, if not his underlying peripherals, were much better in the second half than the first; he dropped from a 4.72 to 3.20 in terms of ERA but just 4.07 to 3.89 in terms of FIP. While his average four-seam fastball velocity was unchanged from 2022 (98.0 mph according to Statcast) and that of his sinker only dipped from 97.8 to 97.6, batters hit him a bit harder, and his strikeout, walk, and homer rates eroded substantially:

2022 23.4% 5.6% 17.7% 0.63 620 87.8 5.2% 38.5% 2.90

In the grand scheme, that Alcantara ended up needing Tommy John surgery is altogether unsurprising, as he’s been one of the game’s hardest throwers at high volume. His average four-seam velocity has led major league starters for three straight seasons, with his average sinker velocity coming within 0.1 mph of doing so — and one can certainly quibble with the 2021 rankings, as Statcast considers Gerrit Cole qualified on the basis of his meeting the total threshold of 1,500 pitches thrown, though just 25 of his were sinkers that year, compared to 873 for Alcantara.

Alcantara has been even further ahead of the pack in terms of workload. His total of 228.2 innings in 2022 is the majors’ highest since ’16, and one of just two seasons of the 2020s that cracks the top 25 of what we might call the Statcast era (2015 onward):

Meanwhile, Alcantara’s three-year total of 619 innings (including 205.2 in 2021) led the majors, 28 ahead of Cole and 39.2 ahead of third-ranked Aaron Nola. His six complete games from 2022 was higher than any team total since ’19, and higher than any individual total since Chris Sale threw six in ’16.

As noted in a variety of ways here over the years, starting pitchers aren’t throwing as many innings as before, a trend owing to numerous factors, including teams’ awareness of the times-through-the-order penalty and ever-rising velocity and strikeout rates. The disruption caused by the pandemic-shortened 2020 season is part of the equation as well, as starter workloads just haven’t been rebuilt to the same degree in subsequent seasons.

Alcantara publicly embraced a workhorse approach, telling CBS Sports’ Matt Snyder last year, “My mentality is to go deep into games and finish my own games. I’m that guy who likes to compete. I’m that guy who likes to challenge the hitter. I’m the guy who will go out and fight.”

The pitcher emphasized last year that he wasn’t throwing at maximum effort all of the time, telling The Athletic’s Andy McCullough, “If you start the game using all your velo, maybe you’re going to get tired in the third inning, maybe in the fifth… But I’m not like that. I like to start the game nice and easy, relax a little bit. After the fifth inning, I’ve got to use all my powers.”

Here it’s worth noting that Alcantara’s efficiency did mitigate his workloads to some extent. In 2022, he reached or exceeded 110 pitches in a start — a rather arbitrary threshold to begin with — just five times, well below the Statcast-era maximum of 18 reached by Sale in 2017 and Trevor Bauer in ’19. Note that the majors-wide total of such outings plummeted from 219 in 2019 to 60 this year. Alcantara didn’t even lead the majors in 110-pitch outings in 2022, as Luis Castillo had six between his stints with the Reds and Mariners. Alcantara did so just three times in 2023, and for the three year period never once threw 110 innings in back-to-back outings. His streak of seven consecutive starts with at least 100 pitches from May 16 to June 19 in 2022 was matched or exceeded nine times from 2021–23, including twice by Corbin Burnes.

Even without pitch counts going into the red, it’s not surprising that Alcantara’s combination of volume and velocity would carry a cost. What’s striking about the increasing rarity of pitchers reaching the 200-inning plateau (just five did it this year, down from eight last year, and 15 in 2019) is that the pitchers who repeat the feat inevitably pay the price. Twenty-four pitchers have thrown 200 innings in a season multiple times since 2015. Five have had Tommy John surgery since doing so, and the attrition rates on the others at least feels high:

Yellow = underwent Tommy John surgery. Blue = retired.

None of those retirees made it to their age-40 seasons, or came close to reaching 3,000 innings, once a common career plateau. Lester retired after his age-37 season and 2,740 innings. Price (age-36 season, 2,143.2 innings), Hamels (age-36 season, 2,698 innings), Shields (age-36 season, 2,616 innings), Samardzija (age-35 season, 1,645.1 innings), and Porcello (age-31 season 2,096.1) didn’t even last that long. The book may be closed on Archer (age-33 season, 1,357 season) as well, as he didn’t pitch this past season. Corbin, Keuchel, and Kluber probably aren’t long for the majors judging by this year’s performances, and I haven’t seen a single report of anybody calling to inquire about Bumgarner once the Diamondbacks released him in late April with about $34 million still remaining on his contract. Meanwhile, Bieber, Mikolas, and Nola didn’t have anything close to their best seasons in 2023.

Aside from the future Hall of Famers (Greinke, Scherzer, and Verlander), Cole is the rare pitcher here who has not only survived but thrived, perennially throwing 200 innings while drawing Cy Young consideration, though we’ll see how he holds up down the road. Cole aside, I don’t think that set of outcomes bodes well for repeated trips to the 200-inning line, at least not unless conditions change to make pitching less stressful — which would probably involve deadening the ball to take away offense, and/or further limiting pitching staff sizes to put a premium on eating innings via shorter plate appearances.

Anyway, since I last checked in on Tommy John surgery trends in late August, the list of major league pitchers receiving the surgery has expanded to include both Alcantara and Bautisa, with Shohei Ohtani apparently receiving the internal brace procedure — which involves the creation of an artificial ligament using collagen-coated suture tape, can only be used on certain types of tears, and has a shorter recovery time than traditional Tommy John. That brings this season’s total to 24 major league pitchers, two shy of last year and down from 30 in 2021.

If there’s good news for Alcantara, it’s that he’s got some security here. Had he not signed a five-year, $56 million extension in November 2021, he would have hit free agency after his year of rehabbing. Instead, he’ll make $9 million next year (up from $6 million this year and $3.5 million last year), and then $17 million apiece in 2025 and ’26 with a $21 million option and $2 million buyout for ’27. That’s less than he would have earned as a healthy pitcher reaching free agency, of course, but that’s the risk/reward tradeoff he made by signing that extension.

As for the Marlins, who are coming off their second playoff appearance in four seasons, they have three starters in their age-25 seasons, all of whom turned in above-average performances in terms of ERA and FIP this year in Jesús Luzardo, Braxton Garrett, and Edward Cabrera, only one of whom is arbitration-eligible (Luzardo). Eury Pérez, who’s just 20 and who made the leap from Double-A in May, will get a full season in the rotation. Trevor Rogers, who was limited to four major league appearances by biceps and latissimus dorsi strains, will hopefully be healthy enough to compete for a spot, but the team will probably need help via free agency to fill the large footprint of Alcantara’s innings.

Hopefully, Alcantara will come out of this on the other side still an exceptional pitcher. Still, it’s worth remembering that for as much as we’d all like to see starters throw more innings like the days of yore — a yearning that becomes especially acute when juxtaposed against postseason starter management (see José Berríos and Ranger Suárez) – the deck is stacked against them, and it will take more than bravado to reverse it.

Remember when everyone was like “Sandy Alcantara is a real pitcher, he goes deep into games and is durable! Not like these other pansies!”

I’m not seeing how there’s any way to tell whether the workload was the cause of the injury. TJS is very common among pitchers no matter the workload – starters, relievers, fastballers, curveballers, whatever. I’d like to see a proper study of the cause. For all we know it’s the increased arm strength relative to ligament. I have no idea and it doesn’t seem like anyone else does either

According to Jeff Passan’s The Arm, workload is indeed correlated with TJ surgery. The problem is that the workload in question is total workload over the lifetime of the pitcher, of which MLB workload is a drop in the bucket.

If you pitch more innings, you have a greater opportunity to tear the UCL as the odds for it increase. I am now curious about the book and want to read it. In my mind, something more is involved. Hudson Yeun did a statistical exploration of high velocity and TJ surgery (easily found with a web search) that strongly correlated the two variables. Correlation is not causation, but the arm is subjected to more forces including torques at higher throwing velocities, so it logically makes sense to me.

I would love if Jeff Zimmerman would wade into this discussion. I remember at one time in the past he did a study that tied pitcher average velocity to the chance of being on the DL the following year. As I recall the data showed a nearly direct correlation of velocity to DL chances the next year.

Yeah, I think as far as we know, every pitch has a tiny chance of being the one. More pitches, more chances. With high velo guys the chance is maybe a tick higher.

I agree. What I’ve been seeing is there is a stronger correlation with velocity than innings pitched or total pitches thrown. Also as pitchers age they are more likely to break. At some point Cole is going to break and people will go on about innings pitched when he’s just a pitcher who is 33.

The chart of pitchers going 200+ innings isn’t very convincing to me. The claim that pitchers used to go to age 40 is dicey at best (between 1969-1993, about one starting pitcher every two years made an impact past his 40th birthday).

A lot of the blue highlighted pitchers don’t have known injuries, and seemed to have just declined into pumpkins. It seems at least as plausible that a lot of these guys just don’t throw hard enough anymore, which is more urgent in today’s game.

The idea that there is a link between heavier usage and injury is a sensible one, but do the data really back it up? I wouldn’t be surprised if usage rates (among pitchers that are used as starters) matters way, way less than velocity does, which of course is not at all ignored

I also wonder with the big $$ now, if some pitchers just decide “Heck with it, I’ve made $100+M, do I really want to keep doing this?”. A guy like David Price is a perfect example, to me.

Back when pitchers weren’t making 8 figures a year, a pitcher like Price may not had life changing $$ saved & been forced to figure out a way to still compete.

I’m sure guys like Gaylord Perry, Don Sutton, Phil Niekro, Luis Tiant, etc loved the game, but, if they had pocketed $200M, would they still have been trying to go out there in their early 40’s with diminished stuff, trying to get 1 more year making $500K?

What it would take for teams to develop more “workhorses” is to simply have every guy throw until something tears, essentially admitting in advance that pitching at a high level is functionally a suicide mission — many of your arms won’t make it.

That is how teams did this in the “days of yore”.

(To be clear, I am not recommending this approach.)

You just keep working all your horses, and then the ones that didn’t die were the workhorses. The dead ones probably died because they lacked character.

I’ve heard that theory before – that the reason so many guys could pitch every 4th day and throw 280 innings was that anyone who COULDN’T do that weeded themselves out in the minors.

I think that is part of it, but I think it is also due to guys throwing harder, with more consisten max effort, and maybe more (and harder) breaking stuff.

My take:

Nolan Ryan and JR Richard brought back the strikeout. JR Richard’s career ended for medical reasons but it might not have if they treated it properly. But Nolan Ryan was a freak of nature who probably threw more MLB pitches than anyone else in history and harder than all but maybe one or two who came before him.

People realized how much more valuable strikeouts were than pitching to contact thanks to guys like Ryan, and started developing pitchers with greater velocity, which sort of worked out okay. You didn’t see this rash of arm injuries in the mid-2000s, after all. But it didn’t help either, and the problems that it caused may have been covered up by steroid use anyway.

But then everyone realized that movement and spin was what was doing a lot of the heavy lifting. So they started teaching guys how to suddenly throw breaking stuff that broke so hard it would dig all the way into the molten core of the earth. And then they came up with breaking balls that actually broke backwards through time. And maybe you could throw these sorts of physics-defying balls at 88 MPH but at 95 MPH your arm just comes loose.

And it’s hard to fault teams and players for doing this, because the returns are so enormous, but the whole thing is based on a lie because guys like Nolan Ryan and Randy Johnson and John Smoltz and Justin Verlander are the exceptions and not the norm. The human body isn’t meant to throw pitches that break the space-time continuum. Every time I see someone write up “this prospect’s stuff got so much nastier” I just start counting down the clock until their arm blows up.

At the end of the day, the root causes of these injuries are:

1) Effort level and velocity. EVERYONE is a reliever now. If you max out at 96, you sit at 92-93. If you max out at 92, you sit at 88-89. There is no such thing as saving bullets or controlling velocity; guys go closer to all out now than ever before. And because MLB’s been slow to react and has allowed teams to expand their pitching staffs, therefore turning everyone into a short burst, high effort reliever, now everyone throws as hard as humanly possible and stamina/durability have been mostly forgotten as key elements of a pitcher’s toolbox. Solution? Not an easy one. This may very well be a “can’t put the toothpaste back into the tube” type deal, but a combination of expansion (at least two more teams) and shrinking pitching staffs, paired with a deader baseball to control the run scoring environment, would be my choice. You need to force teams into putting durability and stamina back into the priority list, and strict rules are the way to do this.

2) The amount of pitching a lot of kids do before they even turn pro. I don’t think I need to speak a lot on this. Many pitch year round, which is insane, and the chasing velocity process is happening at ages that are way too young.

At this point, we should all know that there is no way to keep guys healthy when they’re throwing as hard as they can all the time. You can treat pitchers with kid gloves, as the Dodgers do, or you can let them pitch, as Sandy did. Both ended up breaking. There is no solution other than FORCING teams to change the way pitchers train and throw. Would that stop injuries? Absolutely not. Even back then, pitchers got hurt often, they just either pitched through it at the cost of pain and effectiveness, or were lost to time as a what if. But it’s never been more common than today.

Ball’s in your court, MLB. You can keep burying your head in the sand and pretend nothing’s happening, or you can take actual long term measures to prevent the health and stature of your sport’s most important position.

Ugh. If you deaden the ball you just kill scoring. Pitchers will still chase strikeouts (read: velocity) as they will always be the best way to get outs.

Avoiding arm injuries is the sort of long view item that there just isn’t enough incentive for. For teams, it only really matters for the small handful of guys that get 10-figure contracts. For players … well … gambling on invincibility pays significantly better than the alternative.

It’s just going to continue this way until someone figures out a better usage pattern. It’s probably going to be the end of the true starting pitcher, and old men everywhere will bemoan how things changing has caused them to face their own mortality, but baseball will go on anyway. We’ll just see something like regular tandem starters or a proliferation of 6-9 out guys.

The fact is that velocity plays. Period.

If the starting pitcher dies, baseball dies with it, so they better not allow that to happen. And obviously velo plays, they key is to make it so there are more ways to get batters out than throwing 95+ consistently. Pitchers could still chase max velo, it’s the constant 100% effort that’s the issue.

I lived in the era of Bob Lemon, look him up and be amazed, Whitey Ford, Don Newcombe and have followed the game very closely ever since. How to keep pitchers on the bump has been the question throughout The Mets began using a 5-man rotation in 1968 but Steve Carlton made 38 starts as late as 1982. Many will say that he threw the greatest slider ever but his arm stayed glued on, as did the arms of Gibson, Seaver, Lolich and Ryan. Why, that question has never been answered satisfactorily and it is no different today. The answer was actually there for all to see but it isn’t an answer anyone wants to hear. Despite every new idea as to why, everything put forth is still just a guess. and I have heard them all in 75+ years, 4 man rotations, the slider, the splitter, high velocity, Whether we are talking about Karl Spooner or Sandy Alcantara the answer is the same as it has always been, some arms fall off and some don’t and, teams are too frightened to find out if their ace is Bob Gibson or Jacob deGrom.

A huge part of the reason guys back in the 60’s and 70’s could put up massive IP totals is the bottom of those lineups were total black holes. For starters, both leagues didn’t have a DH until 1973 so both leagues had an automatic out at the bottom of the lineup. Catcher has always been a black hole. But beyond that, everyone wanted glove men at 2B and SS. As a result, pitchers could coast through the bottom of the lineup regularly. Add in the free outs with sacrifices and caught stealings and pitchers were able to make it a lot deeper into games with less stress on their arms. (There is also ample evidence that foul balls have increased dramatically over the years. Forget where I read that but I do remember reading that somewhere)

As some evidence – median wRC+ by position – 1970’s v 2010’s:

  • 2B: 81-82 in the 70’s, 94 in the 2010s
  • SS: 73 vs 88-89
  • C: 88 vs 87-88
  • 1B: 113-114 vs 108
  • 3B: 94-95 vs 101
  • LF: 108 vs 99
  • CF: 101-103 vs 97-98
  • RF: 108 vs 106
  • DH: 103-105 vs 108
  • P: 1 to -5 vs -12 to -13

So you can see that the middle infield (& to a lesser extent 3B) was filled with just far inferior hitters to today’s game. And since wRC+ is a zero-sum game, their dragging down the average made all the other positions (except DH) look better than today’s game.
