Abstract: A method for performing pitch classification includes receiving, at a computing device, one or more pitch properties corresponding to a ball thrown by a pitcher. Pitcher information corresponding to the pitcher is also received. The pitcher information includes at least an identification of one or more pitches that are in a repertoire of the pitcher. A classification of the pitch is determined using at least a pitch classification algorithm, where the classification of the pitch is based at least in part on the one or more pitch properties and at least in part on the pitcher information.
