Dr. James Andrews releases a position paper on the Tommy John surgery epidemic

37 Comments

We have posted about this a few times when Dr. James Andrews has given interviews on the subject of what he calls an “epidemic” in UCL tears and attendant Tommy John surgery. But now he and his American Sports Medicine have released a position paper on the matter.

In it he outlines the risk factors for Tommy John surgery, common misconceptions about it and his recommendations for pitchers and teams to limit the risk of needing it. As for that last part, this recommendation is likely to get the most play and, if heeded, affect the most change:

Do not always pitch with 100% effort. The best professional pitchers pitch with a range of ball velocity, good ball movement, good control, and consistent mechanics among their pitches. The professional pitcher’s objectives are to prevent baserunners and runs, not to light up the radar gun.

I think major league teams know that in practice once they have a pitcher and are developing him. But the defining trait of a scout is his radar gun, and young pitchers are conditioned to want to light it up when they see a scout checking them out. Good pitchers change speed and create movement. Young pitchers get noticed, however, when they throw in the 90s. It’ll be interesting to see if this changes that at all.

Anyway, consider thus must-click material. And something to bookmark if you’re at all interested in the subject.

The Marlins designated utilityman Derek Dietrich for assignment, Clark Spencer of the Miami Herald reports. This comes amid a flurry of moves on Tuesday night as teams prepare their rosters ahead of the Rule 5 draft next month.

Dietrich, 29, is coming off another strong season in which he hit .265/.330/.421 with 16 home runs, 45 RBI, and 72 runs scored in 551 plate appearances. He played all over the diamond, spending most of his time in left field and at first base. Dietrich also played some second base, third base, and right field.

Dietrich is entering his third of four years of arbitration eligibility. He earned $2.9 million this past season and MLB Trade Rumors projects him to earn $4.8 million in 2019. Cutting Dietrich represents a bit more than 4 million in savings for the rebuilding and perennially small-market Marlins. Dietrich should draw some interest, so the Marlins could end up trading him rather soon.

Wonder how J.T. Realmuto, now the longest-tenured Marlin, is feeling right about now.
