Batter Up, known as Gear Stadium (ギアスタジアム) in Japan, is a baseball game developed and published by Namco for the Sega Game Gear. It is a handheld entry in Namco's World Stadium series, itself inspired by the earlier Family Stadium series for the Famicom, whose first entry, Pro Yakyuu Family Stadium, dates back to 1986.

Players have a cartoonish, "super deformed" appearance. The game has a two-player mode which makes use of the Gear-to-Gear Cable peripheral.

An updated version titled Gear Stadium Heiseiban (ギアスタジアム平成版) was released in Japan in 1995.


The game follows the rules of baseball. Players choose from 14 fictional "Namco League" teams, each with their own unique players and statistics. Players pick their starting pitchers, the length of the game (5 or 9 innings), and the venue (Park or City). The City stadium has high walls that make hitting home runs more difficult.

When pitching, use Left and Right to position the pitcher on the mound. Throw the ball with 2; use Left and Right for a breaking ball, Up to throw a change-up (slow pitch), or Down to throw a fastball. Faster pitches are harder for the batter to hit but more likely to travel farther or potentially result in a home run. The batter is eliminated when three strikes are thrown; the batter gets a free base if the pitcher throws four balls or a "beanball" (batter hit by pitch). The player can substitute a relief pitcher by pausing the game with  START  and pressing 2.

When fielding, the D-pad controls all of the fielders simultaneously (with the camera focused on the one closest to the ball). The player can have the nearest fielder jump or dive toward the ball by pressing 2. Once the ball is in possession, throw it to base by pressing 2 while holding a direction corresponding to the base (Right for first, Up for second, Left for third, or Down for home) or press 2 by itself to throw to first base.

If the opponent has players on base, the player can press 1 while pitching to switch to the fielding view in order to tag out players who might be trying to steal a base.

When hitting, the D-pad positions the batter in the batter's box. Swing with 2; the batter stops the swinging motion when the button is released. The player can bunt the ball by releasing 2 mid-swing. While the pitcher is winding up, the player can try to steal a base by holding a direction corresponding to a base and pressing 1.

Runners automatically advance to the next base after the ball is struck; they can be instructed to run to another base by holding a direction corresponding to the base (Right for first, Up for second, Left for third, or Down for home). If they are between bases, they can be ordered to return to the last base with 2.

The player can substitute a pinch hitter by pausing the game with  START  and pressing 2.

Hitters that twirl their bat when approaching the base have extra confidence and are more likely to get a good hit. In the seventh inning, every batter is a prime hitter.
