Many people use the word “epidemic” when referring to the rate at which baseball players, from the professional ranks down to high school, have been undergoing ulnar collateral ligament (UCL) reconstruction surgeries, more commonly known as Tommy John surgeries.

While torn elbow ligaments have been problematic at all levels of baseball, this article will focus on the latest statistics, trends and information with respect to Tommy John surgeries in major league baseball.

MLB Surgeries

There was promising news regarding the number of Tommy John surgeries performed on major league players in 2016.

2016 surgery total as of Oct. 6

This year saw the lowest number of Tommy John surgeries of any year in the past decade. The one disclaimer is that the year is not over yet, so there may yet be additional surgeries to add to the tally. In particular, Oakland right-hander J.B. Wendelken is to get a second opinion this week on his injured right elbow, and is not optimistic he can avoid a UCL reconstruction.

While some or maybe even most of the reduction in surgeries observed in 2016 could be just random year-to-year fluctuation, there were also more public signs of players trying alternative therapies than in prior seasons.

Garrett Richards is the most prominent example of a different course of action looking so far so good, as after a stem cell injection in mid-May in the area of his partially torn UCL, he has progressed to the point where he threw 25 pitches in an instructional league game last week and came away feeling healthy.

Here is a partial list of major league pitchers who have attempted platelet-rich plasma (PRP) and/or stem cell injections specifically for their UCL injuries (i.e. not flexor tendons or other parts of the arm or body).

Clearly the results have been mixed, as some players have returned successfully after the injection and rest and rehab, some have returned but then shortly thereafter been re-injured, and others have not progressed well enough to return and ultimately required Tommy John surgery anyway.

Given that there is some level of success with these injections, and when successful they lead to quicker return times, I expect this trend to continue next season. The potential for success is also backed by this recent published article on the subject.

These injections are likely to be especially popular if a pitcher has a low-grade UCL injury, and even more so if that injury occurs at a time in the year where the potential of delaying surgery by a few months while a preferred alternative avenue is explored does not much impact the expected return date of the player.

Major League Pitchers

In the 2016 regular season, 742 players threw at least one pitch in a major league baseball game. Of those, 22 were position players mopping up in blowout games or forced into action in long, extra-inning affairs. Of the 720 true pitchers who appeared in a game this season, 190 have had Tommy John surgery. This group makes up 26.4 percent of all active major league pitchers.

In addition, 18 pitchers who ended the season on the major league disabled list but did not see any game action in 2016 have also had Tommy John surgery. These 18 made up 62.1 percent of pitchers who concluded the year on the DL without appearing this season, and when we include these pitchers to arrive at a percentage of all major league pitchers who have had Tommy John surgery, it brings the rate to 27.3 percent.

Here is a full list of major league pitchers who have undergone this surgery, broken down by team. Note that there are 13 pitchers who appeared for two teams during the season. These pitchers are listed for both teams, but counted only once in the major league total.

MLB Games

With more than a quarter of all pitchers having had UCL reconstruction surgery, and ever-growing bullpen specialization increasing the number of pitchers used in each game, it seems not a game goes by where broadcasters aren’t mentioning the surgery in discussing a player as he works from the mound.

In fact, I calculated the percentage of regular season major league games in 2016 featuring at least one pitcher who has had Tommy John surgery, and the result was a quite staggering 86.4 percent! This means on a typical night with all teams in action, you could expect that 13 out of the 15 games will involve a pitcher whose career has been extended with the help of this surgery.

I know there are fans who lament how often broadcasters mention Tommy John surgery, but at least it is apparent just how often pitchers dealing on your screen have undergone this procedure. Here is the breakdown by team of how many games this season they played in which one or more pitchers (on that team or the opponent’s team) have had Tommy John surgery.

Team TJ Games TJ Games %
Indians   158 98.1%
Marlins   157 97.5%
Athletics   157 96.9%

MLB 4,198 86.4%

Note that Cleveland played only 161 regular season games this year, meaning the Indians finished only three games all season in which no pitcher appeared who’d had Tommy John surgery. Those games were June 11 at the Angels, then back-to-back on June 21 and June 22 versus the Rays. In those latter games, the Indians received complete game efforts from Corey Kluber and Trevor Bauer, helping to reduce the total number of pitchers entering the game and hence the likelihood of involving one who’d recovered from a UCL reconstruction.

Major League Returns

There were 20 players who returned to the majors this season after playing their last game prior to Tommy John surgery at the major league level.

Chase Whitley P 9/11/2016                 16
Jason Vargas P 9/17/2016                 13

Cory Luebke returned to the majors close to four years after his original Tommy John surgery failed: The tendon graft became “yellow and mushy,” forcing him to undergo a revision surgery and restart his rehab clock. Frank Herrmann is also a nice story, finally getting back to the bigs after more than three years and time spent at Triple-A in four different organizations.

Jason Vargas returned just days early enough to break a trend that I’d noticed in recent seasons: Starting pitchers have not been returning until 14 months or more (rounded to the closest month) after having Tommy John surgery. Here are the numbers by year of surgery:

Year of TJ 13 months or fewer 14 months or more
2015 1  5
2014 0 11
2013 1  5
2012 7  9
2011 4  3
2010 2  2
2009 4  3

Only two pitchers (Gavin Floyd and Jason Vargas) out of 22 who were major league starting pitchers at the time of their Tommy John surgery since the start of 2013 have returned to the major league level in fewer than 14 months. This represents just 9 percent of all starting pitchers who had the surgery between 2013 and 2015. By contrast, 50 percent of starting pitchers who had the same surgery between 2009 and 2012 returned in 13 months or fewer.

This 2013-2014 period roughly lines up with a time in which multiple major league pitchers were forced to undergo quick second Tommy John surgeries (Daniel Hudson, Cory Luebke, Brandon Beachy, Jarrod Parker, Jeremy Hefner, Kris Medlen and Jonny Venters twice). Perhaps organizations (and agents) put the brakes on rehab schedules in response, in an effort to prevent revision surgeries for their players.

I only really know the story of how the Jays got their pitchers, but it seems like only Hutchison (now former Jay) was homegrown- though I’m not sure when he had his. I believe Osuna had his before he came to the Jays. Everyone else had theirs before coming to the Jays.

Could the Jays know something no one else does? Or just luck of the draw?

Antolin too- don’t know my prospects like I should.

Is there another Carl Crawford, that I can’t find on baseball-reference, who was a pitcher?

No you’re right he’s the outfielder. That table should say MLB Players. But he did have a PRP injection, and ultimately had Tommy John surgery.

Wow. I totally forgot about Jonny Venters.

Is it a coincidence that the Biogenesis scandal broke in 2013, or could alternative treatments have shortened the rehab times for surgery in the 2009-12 sample?

The article headline is misleading. There needs be to at least another year to really make any statement about what direction the rate of surgeries is headed.

Completely agree, article shows 2016 was a down year, but rates seem to be mostly random noise, certainly not a trend towards decreasing. The Pearson R value is 0.2675 which is not significant but actually suggests a increasing trend over the 10 years mentioned.
