Blake Treinen Undergoes Shoulder Surgery

  • by

The Dodgers announced to reporters, including Fabian Ardaya of The Athleticthat right-hander Blake Treinen has undergone “right shoulder labrum and rotator cuff repair surgery.” The recovery process is about 10 months, meaning it’s possible Treinen will miss the entire 2023 season.

After a dismal 2019 campaign, Treinen was non-tendered by the A’s and signed a one-year, $10MM deal with the Dodgers for 2020. It was a nice bounceback season for him, as he posted a 3.86 ERA while getting grounders on an incredible 64% of balls in play. The Dodgers were impressed enough to re-sign him for two years and $17.5MM with a 2023 club option worth $8MM.

In 2021, he took his game up a notch. Although his strikeout rate had been just above 20% in 2019 and 2020, he shot it up to 29.7% last year. He still got ground balls at a really strong 52.6% clip, helping his ERA drop down to 1.99. He also got pushed into more high leverage situations, earning seven saves and 32 holds.

2022 hasn’t been as pleasant, unfortunately. He appeared in three games in April before landing on the IL due to shoulder discomfort. He was transferred to the 60-day IL in May but the Dodgers nevertheless agreed to an extension with Treinen shortly thereafter. The extension was for $8MM in 2023, effectively guaranteeing the club option that was already in place. In addition, it came with a new club option for 2024, with a value somewhere between $1MM and $7MM. Where it falls in that range will depend upon Treinen’s health and other factors over the course of the deal.

Treinen did return to the hill this year, making a couple of appearances in September before returning to the IL. He was activated for the NLDS and made one postseason appearance, although he must have been using the last bits of strength his shoulder had. It was reported a couple of days ago that surgery seemed to be likely, and it has now indeed come to pass.

This is surely a disappointing development for Treinen personally but also for the Dodger club that took a gamble on him six months ago. They will now be on the hook for $8MM next year and that is quite likely to be a sunk cost. The 10-month recovery window makes it possible Treinen returns very late next year but he will have to rebuild strength and effectiveness after a long layoff. That makes it tough to count on him for anything. The exact calculus that goes into determining the final value of the 2024 option isn’t known, although Treinen’s upcoming extended absence will likely result in it finishing in the low end of that $1-7MM range. The club will surely make their decision based on how his health responds between now and one year from now. Treinen is currently 34 and will be turning 36 in June of 2024.
