Science news: Throwing fastballs may be linked to Tommy John surgery in MLB pitchers

Contrary to conventional wisdom, Major League Baseball pitchers who throw a high percentage of fastballs may be at increased risk for Tommy John surgery, according to research at Henry Ford Hospital in Detroit.

Researchers suggest that throwing fastballs nearly half of the time puts pitchers at risk of injury to their elbow. MLB pitchers who have undergone Tommy John surgery threw on average 7 percent more fastballs than pitchers who had no surgery.

Researchers found no statistical differences in other pitch types like curveballs, sliders and change-ups. They also found no correlation between pitch velocity and risk of injury.

The findings are published in the Journal of Shoulder and Elbow Surgery.

“Our findings suggest that throwing a high percentage of fastballs rather than off-speed pitches puts more stress on the elbow,” says Robert Keller, M.D., chief resident in Henry Ford’s Department of Orthopedic Surgery and the study’s lead author. “This leads to elbow fatigue, overuse and, subsequently, injury.”

The Physics of Broken-Bat Homers – The Hardball Times

Good stuff.

The ball doesn’t even know or really care that it broke the bat. It behaves just as if the bat didn’t break and flies off without a care in the world. However, a ball directly responsible for breaking the bat near the handle slinks off as if it has a guilty conscience.

So, next time you see a broken bat result in a weak dribbler, check out the replay. It will most likely show the batter hit an inside pitch near the handle. On the other hand, if you’re lucky enough to see a broken-bat homer, the replay will show a ball hit further up on the barrel. Oh, and make a note for your new authoritative list of broken-bat homers.
