Major League

The 1934 Pacific Amusement Manufacturing Company's (PAMCO) Major League pinball machine, designed by C. Hale and Harry Williams, is an early electro-mechanical (EM) pinball machine with a baseball theme. This original version had a notable flaw: the batting mechanism didn't always work reliably, and games were pulled from locations within 30 days of delivery, prompting the playfield to be redesigned into the Model 40 and Model 44 versions with a "batter automatically up every time."

Major League's gameplay is characterized by mechanics typical of early, pre-flipper EM pinballs -- flippers would not be introduced to pinball until 1947. Players aimed to score points by guiding the ball through the playfield toward baseball-themed targets and holes, with the "batting" gimmick as the game's central novelty.

The design of Major League features a sports-themed cabinet with baseball-inspired artwork. Designer Harry Williams left the company shortly after the game was started, and race car driver and wingwalker Bon MacDougall was brought in to finish the design and file the patent submission that led to the later Model 40 and Model 44 revisions.
