The purpose of this study is to examine the effect of “sacrifice bunt” in baseball, executed when a runner is on first base with no outs. The offensive strategies studied are, “sacrifice bunt”, “base stealing”, “hit-and-run”, “hitting”, and “hitting after first attempting to bunt”. We recorded 846 official games of Japanese Professional Baseball in 2006, and selected 3994 cases to categorize the strategies and the results. The results are as follows:     (1) Following the bunts, the runner on first moved up to second base 81.6% of the time, but the base runner advanced only 40.7% after hitting.     (2) However, following the bunts,the runner on first reached home plate 37.6% of the time. This probability is almost the same as the one after hitting.     (3) The expected number of runs in one inning for each strategy was: 0.73 for bunting, 0.86 for hitting, and 0.95 for the “hit-and-run”.     There are possibilities that the effectiveness of five strategies are not the same as the result of (1) to (3), not in case of a league format and higher skill level. In this study, we didn’t discuss about each case with various situations, but examined many cases (3994) comprehensively. Based on our results we can see that it isn’t advisable to choose the “sacrifice bunt” in this situation. It seems that a more effective strategy for scoring runs is either hitting or executing the “hit-and-run”.
