Home Run Nighter: Pennant League!! (ペナントリーグ ホームランナイター?) is a baseball game developed by Data East for the Famicom and published in Japan in 1989. As a baseball game in the mold of Pro Yakyuu Family Stadium, all the athletes have a cartoonish super-deformed look to them. Home Run Nighter goes one step further than its contemporaries by presenting every batter in the fictional teams that comprise the Pennant League with their own unique sprite. Some will be taller than others, or have exaggerated facial features. It's possible that some of the athletes (and the managers, which appear during the preparation stage) are modeled on actual Japanese players. Home Run Nighter would receive a single sequel in Home Run Nighter '90.
