How many stitches are on the official baseball used in Major League Baseball?

The official baseballs used in Major League Baseball have 108 double stitches as of 2014. Each baseball is hand-stitched and held together with red yarn or string.

The modern baseball has an inner core of yarn that is wound tightly around a small ball of cork or rubber. Two strips of white cowhide are stitched together with the red yarn. Once stitching is complete, the ball should weigh between 5 and 5 1/4 ounces and measure between 9 and 9 1/4 inches in circumference. Rawlings has been the exclusive manufacturer of the official baseballs for Major League Baseball since 1977. Prior to this, official baseballs were made by Spalding.
