As of today, that list consists of 488 names of players who we can confirm with reasonable certainty underwent Tommy John surgery. The other criteria to make the list is that I had to be able to confirm with reasonable certainly at least the year of the surgery. In many cases, I have the exact date of the surgery. This additional requirement is what added a great deal of effort to the search process.
The list includes the name of the player, the date of the surgery, the organization for which the player was playing when the injury occurred, whether or not the player was pitching in the Major Leagues or minors at the time of the injury, and whether or not the player was a pitcher. For players where only the year of the surgery could be determined and not the exact date, the surgery date is listed as January 1st of that year. In a few cases, where both the month and year could be determined but not the exact date, the surgery date is listed as the 1st of that month in that year. In cases where a player underwent the surgery prior to being drafted, they are listed as playing for the organization who ended up drafting them subsequently….
That being said, it is not surprising to me to see the Chicago White Sox as having the fewest names on the current list. While pitching coach Don Cooper does not appear to be a fan of incorporating new biomechanics research into his system, he does have a solid track record to fall back on with respect to his pitchers’ health. Much has been written about the importance of long time White Sox trainer, Herm Schneider, and his success at keeping his players on the field….
Jose Rijo appears to be the all-time leader in Tommy John surgeries, with five. Surprisingly, it was not simple to determine the exact years of his procedures, so he is also not on the confirmed list at this point.
