Can sensors prevent elbow injuries in baseball? (Yahoo Sports)

As Pirates prospect Matt Benedict tossed a baseball on Roberto Clemente Field at Pittsburgh's minor league complex late one Sunday afternoon, five blue sensors attached to his body recorded 39 sets of measurements ranging from shoulder rotation to hip speed to stride. Now they hope for a new level of diamond data that will stop the spate of torn ulnar collateral ligaments in elbows and an epidemic of Tommy John surgeries. ''It's the next sabermetrics,'' said Glenn Fleisig, a Ph.D. in biomedical engineering who directs research at Dr. James Andrews' American Sports Medicine Institute.
