1. A system that facilitates evaluation of pitching efficiency of a pitch of a baseball by a person, comprising:

  • a control component that receives and synchronizes motion data monitored by each of a set of one or more inertial measurement units (IMUs) that are attached to at least the person to create synchronized motion data, wherein the synchronized motion data includes data indicative of one or more of arm speed, arm slot, wrist motion and hand motion during the pitch; and

    an analysis component that analyzes the synchronized motion data in connection with a motion standard and generates pitching efficiency feedback based at least in part on the analysis, wherein the pitching efficiency feedback comprises information relating to one or more of grip and ball release including arm slot, wrist motion and hand motion.
