One of the most important players in baseball is the pitcher. His role is simply defined but not easy to execute. Pitcher must throw the ball in a way to pass 18,44 m from pitcher mound to catcher with diversity of throws to confuse the batter not to hit the ball. If pitcher only had one throw up his sleeve, batters would quickly figure out how to swing to hit the ball and score points for their team. Because of these facts every pitcher has various throws, that have different curves of flight, speeds, and placements in the shock zone. With different throws the pitcher tries to eliminate the batter with the least amount of thrown balls.
In this diploma I tried to define and describe the flight paths of four different throws. Also I measured the speed of the flight of the ball. For accurate analysis of the flight of the ball, I filmed the throws from various viewing points and then compared the results with theoretic calculations for each different throw style.
The agreement between the theoretical results from literature and my measurements is reasonably good.
In the thesis the names of the throws are written in English because there are no official translations into Slovenian language. Also there is no official Slovenian term for baseball so English term is used for the name of the game.
