直球曲球:(我球名没法很好翻译,结束了大家要更正哦)
直球曲球是变化球中非常常见的一种球。这是我的初学曲球与指关节曲球的一种变异。
直球曲球需要先掌握我的初学者曲球,因为两种球是运用相同原理的。当然你没有一定要从初学者曲球练起(许多职业选手都是直接练习)但是那样会是一个很好的选择。
然后当然是握球姿势。
和前一种球的姿势并没有太大区别,除了食指是在球上而不是指向球出手的方向的。
同样的,拇指向上旋,食指中指下压。
在球出手后的手臂姿势略微有所不同。 不像投出直球以后,把手靠向反手方向的膝盖, 你要将投球后的手肘靠向反向的屁股处。参照我发的2楼3楼图(2楼直球,3楼曲球)
The Straight curveball (or "overhand curveball") is one of the most common breaking ball grips. It's a variation of my beginners curveball and my knuckle curveball.
A straight curve requires mastery of my beginners curveball, because many of the same principles that apply to both grips. This doesn't mean that you have to throw a beginners curve (most pitchers actually start right out with this pitching grip). But the beginners curveball is a good place to start.
Then, of course, this pitching grip is the next step.
That's because there is essentially no significant difference between a straight curveball and a beginners curveball, except for the finger placement of your index finger. It should be placed on the baseball as opposed to pointed at a target.
The thumb action of the pitch is upward. The thumb rotates up while your middle and index fingers rotate down.
The arm action on this pitch is a little abbreviated at the end. Instead of getting a nice long arc of deceleration and finishing throwing elbow outside of your opposite knee (as with your fastball), you'll want to bring your throwing-hand elbow to the opposite hip.
This, of course, shortens your follow through, but allows you to really snap off the pitch.
最后的SLIDER,SPLLITER我现在实在不想再弄了。。。先把原文整上来,好心人翻译下吧。。。
How to grip a slider
Ted Williams once said that a slider was "the best pitch in baseball." Whether or not that's true depends on a lot of things, of course, but the slider is certainly an effective pitch for those who can throw it correctly.
A slider is the third fastest pitch in baseball. (The No. 1 fastest is a four-seam fastball and No. 2 is a two-seam fastball.) It's important for pitchers, parents and coaches to learn a proper slider grip and to learn correct throwing technique of a slider to ensure and promote arm-health.
A slider is gripped like a two-seam fastball, but held slightly off-center.
When thrown, try to manipulate the pitch to come off of the thumb-side of your index finger ?NOT your index- and middle-fingers, as with a two-seam fastball ?because a two-finger release will cause the pitch to balance out, which reduces the spin that you are looking for.
Most good slider pitchers grip the outer-third of the baseball and cock their wrist slightly, but not stiffly, to their throwing hand's thumb-side upon release of the pitch. This enables a pitcher to apply pressure to the outer-half of the ball with the index finger.
Avoid any twisting of the wrist upon release.
I have placed the long seam of the baseball in between my index- and middle-fingers, and I have put my thumb on the opposite seam underneath the baseball (as shown in the first picture above).
Some baseball pitchers may find it more helpful to place their index finger along the seam of the baseball since the index finger is the one from which the slider is thrown.
The key with the slider is to hold the ball slightly off-center (on the outer third of the baseball). Remember to slightly cock your wrist, but don't stiffen it. That way, you can still get good wrist-snap upon release. If your wrist is slightly cocked to the throwing hand's thumb side, your wrist-snap will enable you to have the pitch come off of the thumb-side of your index finger, which, in turn, promotes good spin on the ball.
The rest is simple: This pitch should work for itself. The movement on this pitch comes from the baseball spinning off of the index finger from the outside of the baseball ?NOT from twisting your hand underneath the ball. Slider arm speed should remain the same as fastball arm speed.
How to grip a splitter
A split-finger fastball (sometimes called a "splitter" or "splitty") is an advanced pitch.
Typically, it's only a good pitch if you've got bigger hands. That's because the pitch itself should be "choked" deep in the hand. This is how splitters get their downward movement.
Your index and middle fingers should be placed on the outside of the horseshoe seam. The grip is firm.
When throwing this pitch, throw the palm-side wrist of the throwing-hand directly at the target while keeping your index and middle fingers extended upward. Your wrist should remain stiff.
Bruce Sutter, one of the best splitter pitchers in the history of the game, says that it is very important to put your thumb on the back seam, not the front seam. This puts the ball out front just a bit more than a fork ball.
Then, he says, you just throw a fastball.
A very sophisticated and misunderstood point is that the split-fingered fastball should be thrown with back spin just like a two-seam fastball.
