Our preliminary study using high-seamed Wilson 1030 baseballs and a brutal 3-wheel machine. These results were presented at the 2018 APS DFD meeting. These results are based on velocity measurements in the air using PIV. All of these data sets were acquired in a vertical plane. We start with a smooth Continue Reading

Do seams affect trajectory?Post #4
11/29/2020. I will leave the original post unchanged below, but some of our claims here proved to me untrue, or at least more nuanced than we realized. Were I to write this today, I’d point out that seams don’t matter most of the time when the ball has no gyro Continue Reading
Previous study of 2 vs 4 seam pitches Post #1
RPP tackled the same question (why 2 and 4-seam fastballs are different) back in July and came to the same conclusion (that seam orientation in itself does nothing) but from the opposite direction. They showed that a 4-seam pitch with side-spin induced at release would run the same way as Continue Reading
