“That seems simple enough,” confessed Frank, still smiling. “It might seem to explain the ball that curves gradually and regularly, but it does not explain any shoot. If you have followed baseball closely, Mr. Wallace, you have thousands of times seen balls which left the pitcher’s hand and seemed to shoot straight ahead for more than two-thirds of the distance to the batter. Then you have seen them give a sudden jump or shoot to one side or the other. Indeed, some of these shoots are so sudden that the ball almost seems to make an angle in the air, instead of a curve. I am afraid you will find it difficult to apply your explanation to that kind of a ball.” Wallace looked somewhat bewildered. “I have not thought much on that point,” he confessed. “I have,” said Frank, “and so have thousands of intelligent persons. Thus far not one of them can give a satisfactory explanation of the odd shoots of a ball. They say it is the way the pitcher takes hold of the ball—the way it leaves his hand. That is true. But it frequently occurs that two pitchers take hold of the ball in a manner entirely dissimilar to throw the same curve. They do not deliver it in the same manner, and yet the ball curves the same. They know that by taking hold of it just so and throwing it with just such speed they can obtain a certain curve; but ask them to explain why the ball curves and you will see some very puzzled gentlemen. You say the whirling motion of the ball, resistance of the air, and so forth. It may be you are right, but explain the shoot. Photographers have tried to catch it so they could see just how it curves in the air. Thus far these attempts have not proved satisfactory. Fame awaits the man who first explains the shoot and makes his explanation convincing.” The club members had gathered around to hear what Merriwell was saying. They were greatly interested. “Still,” said Wallace, “you would not have us believe that, on one delivery, a ball can commence to curve one way and then reverse and curve the other?” “Really, sir, I am indifferent whether you believe it or not. I know such a thing happens. I know that I can throw the double shoot when I am in good condition and feeling just right. I know I take hold of it in a certain manner, give my arm a certain swing, and my wrist a snap. The ball starts out straight, shoots one way and then reverses and shoots the other. I am not the only one who can pitch that ball. I first saw it pitched by a Maine man, Billy Maines, of Windham. Then I set about trying to get it, and, by the merest accident, I hit upon it. I have tried to show other good pitchers how to throw it, but they are not persistent enough—they get discouraged after a while and give it up. But there is something more wonderful than the in and out double shoot.” “What can it be?” “A rise with a drop on the end of it.” “What? You don’t mean to say anybody can pitch a ball like that?”
