| On the art of pitching in baseball | | | | Â |
|  | | | | It is not easy to hit a ball thrown very fast. |
| It is amazing that anyone can hit a baseball. | | | | Even a very good hitter has difficulty hitting |
| It is small and is thrown into a prescribed target | | | | successfully one of every three or four times he or |
| area. Everyone can see it being thrown and | | | | she comes to the plate. So, if the batter |
| even know when it is being thrown. Yet, it | | | | thinks the thrown ball is outside the strike zone, it is |
| can be so difficult for the batter to hit it. | | | | to the batter's advantage not to swing. Why |
| The stick, or bat, swung by the batter is rather large | | | | go to the effort to hit a ball that is already thrown |
| by comparison to the size of the baseball. | | | | very fast and is outside the target area? |
| Moreover, the batter knows exactly where the | | | | Â |
| pitcher has to stand, and where to expect the pitch, | | | | The essence of the duel between the pitcher and |
| and the batter sees the pitcher who is throwing the | | | | the catch is a decision made each throw of the |
| ball. | | | | ball. On each attempt to throw the ball to |
| Â | | | | the catcher, the pitcher should try to get it in the |
| So why is it so difficult for the batter to hit the | | | | strike zone. Knowing this, the batter gauges |
| ball? It is difficult. Each time the | | | | very early approximately where and when it will |
| batter comes to the plate, the odds of hitting safely, | | | | arrive and adjusts swing calculus accordingly. |
| i.e., reaching first base is only about one in four or | | | | Â |
| one in three or so. That is in the major | | | | Obviously then, the pitcher should not be predictable |

| different but the game is a lot different too. | | | | although constrained on approximately where it must |

| sometimes bounces in front of the plate, or is | | | | more carefully. |
| occasionally thrown over everyone's head. I | | | |  |
| have even seen that in professional games. | | | | On the matter of holding the ball, there are four |
| That is not unusual with youth players especially | | | | fundamental ways to hold the ball in your hand as |
| when the pitcher loses control while trying to throw | | | | you prepare to pitch it. Look at a |
| very hard as his coach has told him to do. | | | | baseball. It has strings. These strings |
| Â | | | | weight a little differently on the ball's configuration |
| Even weak batters, who close their eyes as the | | | | and change its flight characteristics ever so slightly, |
| pitch reaches them, stand a decent chance to reach | | | | but enough that with scientific instruments you can |
| first base, but not by hitting the ball. They | | | | detect slightly different flight characteristics as the |
| collect umpire called "balls" until they have sufficient | | | | ball travels from the pitcher's hand and travels the |
| number to take a "walk" to first base. Then | | | | sixty and one-half feet to home plate. The |
| they probably "steal" second because the catcher | | | | pitcher can hold the ball with the first and second |
| cannot throw accurately that far, but that is another | | | | fingers right on top along the strings at the |
| story for another day. Let it be said that | | | | narrowest point where the decoration draws the |
| both beginning and seasoned pitchers stand to gain if | | | | strings closest together. The pitcher could |
| they can control accurately the number of pitches | | | | also hold the ball along those strings but with the |
| that fall within the strike zone. Outside the | | | | second and third fingers. Because the |
| strike zone means walks, stealing second, and | | | | pitcher's fingers are not all of the same length, there |
| everything that goes with that. Therefore, | | | | will be a slight variation in the way the ball spins on |
| the pitcher should throw strikes. | | | | the way to the catcher based on release order as |
|  | | | | the ball leaves the hand. The pitcher could |
| In my sixty years of watching pitchers pitch some | | | | also turn the ball ninety degrees so the first and |
| terrific games, I have never ceased to be amazed at | | | | second fingers cross the strings, and alternatively so |
| the lack of interest in the fundamentals of what | | | | the second and third fingers hold across the |
| makes for a good pitching duel. Allow me to | | | | strings. So, there are four basic ways to |
| make these observations. To begin, the | | | | hold the ball. These positions are easily |
| purpose of the pitcher is to throw the ball past the | | | | adjusted secretly by the way the glove covers the |
| batter into the catcher's glove. He really has | | | | pitching hand before the throw. We have a |
| to do nothing else. Everyone else on the | | | | first way for the pitcher to introduce intentional |
| team is supposed to field the ball if it comes near | | | | unpredictable variability at least as far as the batter is |
| him, and throw the batter out before reaching base, | | | | concerned. |
| if the pitcher fails in the attempt to do the pitching | | | | Â |
| job. | | | | There are alternatives ways to throw the ball |
| Â | | | | including overhand, overhand with a wrist spin, |
| To the beginner in baseball, as a fan, it must seem | | | | sidearm or even underhanded. All of these |
| strange with all the standing around. Then | | | | variations seem unnecessary and confuse the pitcher |
| suddenly about once or twice a minute the pitcher | | | | as much as anyone else and make the pitcher |
| throws the ball to the catcher or at least tries to do | | | | erratic. I would recommend that the pitcher |
| so. The job of the pitcher on both teams is | | | | throw one basic way, and that be overhand. |
| to do the same. No mystery to it at all. | | | |  |
| Â | | | | There is the matter of target center to |
| However, if we look closely at the activity of pitching | | | | address. I mentioned earlier that the pitcher |
| we see there is the simple repetitive activity. | | | | should aim at the hypothetical center of the batter's |
| The pitcher receives the ball from someone, perhaps | | | | strike zone. Since most pitchers are not very |
| the umpire, the catcher, or one of the other field | | | | accurate, it is unlikely that even one in one hundred |
| players. The pitcher stands on the mound, | | | | throws will hit it exactly anyway, so there is a natural |
| with foot on rubber marker, and then after finished | | | | unpredictability just based on the inconsistent |

| of pitch to expect, he or she prepares to deliver, and | | | | Â |
| then takes a hand position on the ball, raises the | | | | We have a second way for the pitcher to introduce |

| the home plate, and the umpire stands crouched | | | | this measure of variability, even though it is due to |
| behind the catcher, and perhaps slightly to one | | | | systematic control inaccuracy, as another way to |
| side. This may seem a pedantic description | | | | challenge and confuse the batter. |
| of what happens but it is necessary to define | | | | Â |
| exactly the operations involved in the diagnosis | | | | I will add a third intentional variation that the pitcher |

|  | | | | batter. This one is probably the most |
| There is the opportunity of the batter to hit the ball | | | | important variation, that is to control the variability of |
