A cross between a fast ball and a curve ball is called a slider.
When a fast ball and curve ball are mixed together it is called a slider.
Most likely a slider. It has the properties of a curve, but it has the speed of a fastball.
A fast ball is when the pitchers throws the ball straight at the strike zone, it doesn't curve (curve ball) or lower (slider), it goes straight ahead.

Yes, the curve ball curves. This is because of the way the ball is thrown, which is a kind of a spin/jerky fast motion.

Great question. The pitchers command means that his pitches are doing what he wants them to do. If his intent is to throw a curve ball, then the ball will curve. The pitcher has control when the pitches he throws are staying in the strike zone like he wants. If he wants to throw a ball, then he is throwing balls. your curveball can curve, your breaking ball can break, your slider will slide, and your fastball is fast.... however if you can't get it over the plate ( or reasonably within range), you have no control.
slow pitch ball is harder
