Bob Keating pitched in one major league game, going nine innings and taking the loss on August 27, 1887. He is better known for inventing the rubber home plate, which is still used today. Previously, the plate was made of stone, iron, or wood, all of which caused injuries.
A SABR article indicates that Keating was a prolific inventor. He had started as an amateur pitcher in his home town, signed with the Washington Nationals in 1887 but did not appear in a game, and then played his sole game for the Baltimore Orioles, but an arm injury finished his pro career. He had already starting inventing in 1886, and eventually received more than 40 patents for his various inventions. The most famous was the Keating motorcycle. He eventually started a company to manufacture valves. When he died, his obituary in the local paper didn't even mention him playing baseball as a young man. Source: Robert M. Keating, Inventor
He has also been remembered as the inventor of "his version of the ultimate bicycle".
