10th Inning

10th Inning, released by Williams in February 1964, is a two-player electro-mechanical novelty game built around a baseball theme, tapping into the sport's enduring popularity in mid-1960s America. It's classified as a "Bat Game" with mechanical backbox animation, meaning it likely combined a physical batting or animated scoreboard element with pinball-style play rather than following a purely conventional pinball format.

Gameplay revolves around seven hanging targets suspended above the playfield, requiring precise, timed shots to score — a novel and challenging layout distinct from standard slingshot-and-bumper designs of the period.

The game's baseball theme is reinforced through its backbox animation and playfield graphics, evoking the scoreboard imagery of the era. Little is documented about its designer, but the combination of hanging targets and mechanical backbox animation makes 10th Inning a distinctive novelty entry in Williams' 1960s baseball-themed lineup.
