For baseball fans that are smarter than me?

It's not a bad idea but there are so many variables that keep it from being a go to pitch. It has to break late so the hitter can't see the spin and wreck it. It has to break period a hanger hits the batter and puts him on base. It can't be a slow curve or the batter will stay in and hit it hard. I was a college and semipro pitcher and would do this occasionaly with a mid 80's slider but you can't use it too much, it's much less risky to put it in the middle and let it break off the plate to keep it from being hit.

The reality is with that pitch, if the batter is looking for it, he can hit it out of the ball park. It is a inside curve ball, its coming in probably about 80mph and it is begging to be hit out of the ball park.

Most of the time you want to throw a curveball in a location, and if you 'miss' (you mess up, hang it) you want it in the dirt or off the plate out of the strike zone so its just a ball not an extra base hit

Guys with big sweeping curveballs and sliders sometimes have the ability to throw that thing at a guy and have it run all the way across the plate and miss outside. ask ryan howard... guess what, don't miss, because if you do over the plate ryans taking you deep.

its simple, some guys, particularly lefties try it... a lot fo times they strike a guy like ryan howard out, then again, a lot of times thye let a bomb up

when you miss with a breaking ball, you pray its out of the strike zone

if you're sitting on that pitch and you get a slow bending curve ball 9 times out of 10 hes going to end up on base or taking a round trip, but good pitchers do throw it often when they are able to keep the hitter off balance with a good fastball, but i really like the fast balls that start at the hitter and tail back over the inside corner

Starters can't rely on one pitch, period, except the knuckleball.

Some pitchers rely on a variety of curves with differing movement, velocity and placement, but major league hitters would be able to key in to one pitch.

Some pitchers get away with throwing basically all fastballs, but even still they have to be able to mix in off speed pitches to keep hitters off balance.

Hitting is about timing, and pitching is about disrupting timing, and its hard to disrupt timing by using the same pitch over and over again, no matter how good it is.

If batters see too many of those curveballs, any pitcher is bound to make a mistake and end up getting a sore neck watching all those balls clear the outfield wall.
