New study finds major league pitchers 34 percent more likely to be injured than fielders


"Watch out if you are a Major League Baseball (MLB) pitcher prior to the All-Star break. Pitchers are 34 percent more likely to be injured than fielders, according to a study presented today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting. The study looked into the epidemiology of MLB players' injuries from 2002 - 2008. It also found that 77 percent of all injuries to pitchers happen before the All-Star Game."

"The study found that upper extremity injuries accounted for 51.4 percent of all injuries. Lower extremity injuries accounted for 30.6 percent, while back injuries accounted for 7.4 percent and core muscle injuries accounted for 4.3 percent"

Pitchers had a 34 percent higher injury rate than fielders prior to the All-Star Game, according to the study.

"pitchers experienced 67 percent of the injuries to the upper extremity compared to fielders while fielders also had a greater proportion of the lower extremity injuries and injuries to other anatomic regions, according to the study."


"The study also noted that pitchers also spent a greater proportion of days on the disability list (62.4 percent) when compared to fielders (37.6 percent). But both pitchers and fielders spent significantly more days on the disabled list for upper extremity injuries than for lower extremity injuries."

"As for the timing of the injuries, 74.4 percent of all MLB players' injuries occurred before the All-Star break. Pitchers sustained 76.5 percent and fielders sustained 71.7 percent of their total respective injuries prior to the All-Star game. Seventy-nine percent of all shoulder and elbow injuries happened to pitchers before the All-Star game and 74.8 percent of all hamstring, quadriceps, groin and core injuries to fielders happened before the All-Star game."
