Abstract Objectives To compare the bilateral strength characteristics of the wrist flexors, extensors, pronators, and supinators among baseball players. Design Cross-sectional. Setting Laboratory. Participants 30 collegiate baseball players with no recent history of upper extremity injury. Main outcome measures Bilateral pronation, supination, wrist flexion, and wrist extension peak torque (PT) and peak torque to body weight (PT/BW) strength were measured at speeds of 90 and 180°/second. Results Paired t -tests showed that the throwing arm of baseball players produced significantly less PT/BW strength for supination at 90°/second compared to the non-throwing arm ( P  = .001). The throwing arm produced significantly more PT/BW strength for pronation ( P  = .001) at 180°/second compared to the non-throwing arm. Furthermore, the throwing arm had more PT and PT/BW strength for wrist extension ( P
