As of 2020, what is the circumference of an official baseball used by Major League Baseball in America?

A baseball is a ball used in the sport of the same name. Under current rules of America's professional baseball organization, commonly known as Major League Baseball, an official major league baseball weighs between 5-5 1/4 ounces (142-149 g), and is 9-9 1/4 inches (229-235 mm) in circumference. There are 108 double stitches on an official baseball, or 216 individual stitches.

The official major league baseball is made by Rawlings, which produces the stitched balls in Costa Rica. Attempts to automate the manufacturing process were never entirely successful, leading to the continued use of hand-made balls. The raw materials are imported from the United States, assembled into baseballs and shipped back.
