The purpose of this study was to analyze the combination of pitches in college baseball games. The subjects were 2056 pitches that it was thrown a ball in a case of count 0-0 with the right-handed pitcher vs. the left-handed hitter except the case that hitters attempted to bunt in 73 games performed in a season of autumn, 2008 and spring, 2009 of Tokyo Big 6 Baseball League. We used the chart to record the type of pitch, location, and result of pitch, moreover, we recorded the process—seeing or swinging or the foul ball—when the pitchers threw strikes. The results were summarized as follows: 1) Of the pitches, 53.4% were four-seam fastballs and 23.1%, sliders. The pitchers delivered pitches such as a four-seam fastball and a slider with the ball that had a good control, and they attempted to deliver to the outside course or the low course intentionally. 2) The pitchers should throw a strike in advance, because the probability that the hitters had made mistake in batting was considerably high. 3) It was suggested that the hitters preparing for a four-seam fastball basically. Regarding, the course, it was suggested the hitters expecting for the course of center and middle, inside and middle. In addition, the hitters selected from a type of pitch and the course that swung. 4) A curve and a slider were particularly effective to throw the strike by seeing. A four-seam fastball and a two-seam fastball were effective to throw the strike by the foul ball. A splitter and a change of pace were especially effective to throw the strike by swinging. 5) Delivering to the course of inside and low, outside and low, and inside and middle was effective to throw the strike by seeing. Delivering to the course of inside and low as well as outside and low was especially effective to throw the strike by swinging. Delivering to the course of inside and high was particularly effective to throw the strike by the foul ball.
