I've got a fastball, change-up, forkball, curve, slider, knuckle-slider, knuckle-curve, I had about seven pitches I could have used at any time.
I was always a self-proclaimed poor slider.
Sparky Lyle threw me a slider, and it wound up in the seats. We won, and it was a memorable moment.
If I ever find a pitcher who has heat, a good curve, and a slider, I might seriously consider marrying him, or at least proposing.
Later, I could take something off my slider and I could make my fastball sink, so I really had four pitches.
There is no such thing as accomplishing a righteous reform by the use of 'expediency.' There is no such thing as sliding up hill. In morals, the only sliders are backsliders.
I never knew how to throw a fastball, never learned how to throw a curveball, a slider, split-finger, whatever they're throwing nowadays. I was a one-pitch pitcher.
To get the feel of how the slider should roll off of your index finger, use this grip and practice at half speed and roughly half the distance to the mound.
John Wetteland had a very good curveball. He threw it for a strike, too, in any count, any situation. But, he really didn't use it much. He didn't want to throw it. He wanted to throw fastball-slider.
I consciously memorized the speed at which every pitcher in the league threw his fastball, curve, and slider. Then, I'd pick up the speed of the ball in the first 30 feet of its flight and knew how it would move once it has crossed the plate.
How soon do you think it is? Time will tell me. When it's autumn, the leaves fall. When the time comes, I'll know it. [Responding to a question about when he will start throwing his slider in his attempt to comeback from a career-ending stroke.]
