We all know that perceptions can be deceiving (just what color was that dress?).
No. Need <1 for knuckleball.I counted five revs in Garcia's splitter. Would that fall into a knuckle realm?
Sorry, you are wrong. There is no difference in movement between a 4 seam pitch and a 2 seam pitch.
There is a difference in the batters perception. The difference is perceptual psychology, not physics.
Gotta guy from Illinois says your wrong...
I am the aforementioned Nathan. Rod Cross is an Aussi and probably not following this thread. While "conventional" explanations would agree with what you say, the Garcia splitter moves in the opposite direction. The analysis the Cross and I did (more or less independently, although we talk with each other a lot) attributes the "wrong direction movement" to the seam orientation. The arm side of the ball is smoother than the glove side (i.e., the glove side is rougher, on average), and the pitch ended up breaking to the glove side. BTW, the direction of the movement is actually measured, using the PITCHf/x system. So it is not an issue of perception. If you go to my web site, Baseball Aerodynamics, and scroll down, you will find additional stuff about this and similar pitches.

glad you are participating in this. The accessibility to experts on this site continues to blow me away.
