Game-used ball

Same as above except this is a game-used ball. (More specifically, it's David Ortiz's 16th-inning home run from April 10, 2015 at Yankee Stadium.) Gamers are rubbed with mud to reduce the slickness and glare.

Allan H. Selig

This ball featuring the signature of previous Commissioner Bud Selig was used from 2000-2014.

Gene A. Budig

Each league used to have its own ball. Budig was the president of the American League from 1994-1999.

Leonard S. Coleman Jr.

Coleman was the president of the National League from 1994-1999.

Bobby Brown

Brown was the president of the American League from 1984-1994.

William D. White

White was the president of the National League from 1989-1994.

Made in Haiti

Balls were made in Haiti through 1989. A few of them were still floating around the following season when I caught my first four.

Made in Costa Rica

Rawlings moved.

Costa Rica, Part II

Balls are still made in Costa Rica, but shortly after the move, the words disappeared. Why? Because the balls are technically "assembled" there; the components come from all over the world. Import/export laws no longer required those words to be there.

BLEM

Good enough for batting practice but not good enough for games, these blemished balls were stamped and sold at a discount to teams throughout the 90s.

NL practice ball

Some practice balls simply had "PRACTICE" stamped on them.

NL regular ball

Others didn't. ("RO-N" stands for Rawlings Official-National.)

MLB practice balls

Current practice balls are stamped differently.

Green training ball

In 2006 several teams used these balls during BP. They were cheap and ugly and made in China.

Blue training ball

These were used for the next few years, primarily in batting practice by the Nationals.
