I'm a lefty and my 2-seam has always had a natural cut, i.e. in on right-handers. I don't believe it has to do with supination/pronation as I release it the same as my 4-seam. I assume is has something to do with the effects of the air on the seams during flight. I don't throw hard anymore, never did actually, but the ball still cuts at BP speed.

My experience coaching young players is that many naturally supinate and need to be taught to keep their wrist behind the ball, i.e. no supination. I don't think this has to do with the size of their hands, just their inexperience and lack of understanding of the skill.

This does not mean they threw cutters as pitchers. Having thrown a zillion+ bp pitches I know first hand that when I start to fatigue my hand will fall under and I start get around the ball. These are not cutters, but more like hanging sliders. It takes fastball hand speed to throw a cutter properly....A speed never reached while throwing BP.


I thought we were talking about "natural" movement. Someone brought up Catchers, outfielders, and infielders. They aren't throwing "cutters" from those positions are they? Maybe we are talking about two different things here.

Thank you, Rock Dad! I think most righthanders have a natural "tail" to their throws, but many lefties have a "natural" cut, not all or maybe not even a majority, just many. I have never seen a righthander throw with "natural" cut, but that doesn't mean there aren't any.
Chris,

MLB has installed a system called PITCHf/x in almost every MLB stadium that uses 3 cameras that are triangulated to capture the flight of the ball to home plate. The measurements are then calculated to get trajectory, speed, location, and even amount of break (or movement) for each pitch. If you want to see the trajectory and speed of a certain pitcher's pitches, you can check it out at MLB.com's Enhanced Gameday feature which the PITCHf/x system is tied into.

Keep in mind though, not all stadiums have the system installed. PITCHf/x is currently running at Anaheim, Arizona, Atlanta, Boston, Chicago Cubs, Chicago Sox, Cincinnati, Cleveland, Detroit, Houston, Kansas City, Los Angeles, Milwaukee, Minnesota, Oakland, San Diego, Seattle, San Francisco, St. Louis, Texas, and Toronto.

As far as I know it is not yet up and running in Baltimore, Colorado, Florida, New York Mets, New York Yankees, Philadelphia, Pittsburgh, Tampa Bay, or Washington.

The goal is to have it up and running in all 30 ballparks by the end of the year.

Here is a sample of Greg Maddux to show you what I mean. All of the pitches to Eckstein were fastballs.

A fastball with arch???
No one's fastball is perfectly straight. Gravity is going to make the ball drop. The centerfield camera view creates an optical illusion that it does. As you can see Maddux has a lot of sink and tail on his fastballs which is by design. He's not trying to throw straight 4-seamers.

Lincecum is an absolute stud. He blows great hitters away. All of this talk is guessing. Prior had great, repeatable mechanics. So does Greg M. Sometimes guys get hurt because of bad mechanics. Sometimes they don't. None of you are Dr. Andrews. This is a strange game. Guys with perfect mechanics get hurt sometimes. What makes any of you think you know more than the next guy?
Actually a year ago Chris you didn't like Lincecum, all of a sudden he pitches well in the bigs and you are a fan????

Please read for reference:

Also :

I think that Scherzer and Kennedy have mechanical problems (they both take their elbows both above and behind their shoulders) that will increase their risk of being injured. I think this manifested itself in Scherzer's shoulder problems this year.

Ian Kennedy is almost ready for the majors and is lights out down on the farm for the yanks? So Chris what happened to your prediction on this example???

hmmmm.....

First, he does a great job of throwing with his entire body and not just his arm. Notice the tremendous hip/shoulder separation.





Second, notice the "W" in the photo below from today.



Lincecum is still a little too max effort for my tastes, but I think he's got a chance of being a 20-year guy.


Way to go out on a limb. You like a 1st rounder who signed for 2.025 million.

Tell me about the 27th rounder you like.

No it isn't.

I want to see which way his ball moves because it indicates whether he's pronating or supinating the ball through the release point. Pronating is good. Supinating is bad.

Also, I would say that glove-side run is more prevalent than arm-side run by a factor of something like 2 to 1.


A pitch that moves opposite arm side is not run. It is called curve, break or cut.

A pitch that moves arm side to various degrees is called sink, run, tail, bore.

Period. That is what it is. In any league.
