A major league baseball has one continuous seam.
to have grip when someone throws the ball
Simply stitches
place your two fingers (index+middle) on the seams of the baseball and then throw it
it's just yarn, but they are called seams. "The pitcher grips the seams of the ball"
The baseball is a round white ball with red seams and dimensions are 9 in diameter and 5 oz weight.
You get a buzz saw and cut it in half of you rip out the seams.
One seam 108 double stitches
When choosing a baseball you want a ball that feels good. Most people like high seams on the ball because it is easier to grip but, that is just my opinion. It all comes down to what kind of baseball you want.
To evenly distribute the dirt on the ball. Also, to push down the leather part so the seams will show more. The more the seams show the more the baseball will move during delivery. Sometimes it becomes a habit, and they feel they can get a better grip.
well some of the ballls improved from having no seams to seams where to see what i mean u could go to google images and type in balls but that all i no hope this helps!
I am not sure why it has different sized seams but I know why it has seams. The seams help it spin . When you spin it it goes faster. try researching
