“…When a runner attempts to steal second base, the catcher must complete the following actions in a short time: (1) quickly change the caught ball, (2) get up quickly, (3) step on the lead, and (4) throw with a small arm swing. Several studies have examined the mechanics of catchers throwing to second base, 1–7 but there are only a few studies on the throwing time to second base. Eto 8 reported that the throw to second base must be completed in about 2.0 s since a professional baseball player with fast sprinting velocity can run from first to second base in about 3.3–3.5 s, and the time from when the pitcher starts his pitching motion to when the catcher catches the pitch is about 1.3 s.

The purpose of this study was to investigate a baseball catcher’s throwing time to second base using three throwing motion types. The subjects were professional ( n = 4) and college ( n = 12) baseball catchers. Two high-speed cameras were set to capture the throwing motion, while one was set to capture the net on second base. The throwing time of quick throw (throwing motion to release the ball immediately after catching the ball rather than usual throwing motion) was significantly shorter than those of usual throw (throwing motion used during games and practice) and fast ball throw (throwing motion to increase the ball velocity than usual throwing motion). From this result, it became clear that quick throw is the optimal throwing motion when judged by time. Thus, with respect to correlations between variables, there were significant positive correlations between throwing and motion times (usual throw: r = 0.760; fast ball throw: r = 0.719; quick throw: r = 0.767), and between throwing and airborne times (usual throw: r = 0.784; fast ball throw: r = 0.744; quick throw: r = 0.806), for all three throwing motions. However, negative correlations were shown between throwing and release times in usual throw and fast ball throw. The results suggest that, to shorten the throwing time, it is necessary to shorten the hold and stride times and to improve the ability to throw the ball as fast as possible with a shorter motion time.
