HAEGIN announced on September 9 that it has selected cheerleaders Seo Hyun-sook, Cheon So-yoon, and Lee Ye-bin as brand advertising models for its mobile casual idle baseball game '2026 Professional Baseball GO!'.
The three are active cheerleaders for the Doosan Bears, Samsung Lions, and kt wiz, respectively. HAEGIN filmed a new TV commercial and print pictorial with them ahead of the Asian Games baseball matches and the KBO post-season.
Under the slogan 'Cheering at Full Power, GO!', the TV commercial captures messages of support for the national baseball team alongside the atmosphere of the post-season. It uses the cheerleaders' performance to show how the energy of cheering in the stadium is converted into team power within the game.
Making-of videos capturing the commercial shoot will also be released sequentially. Starting with Seo Hyun-sook's version on September 9, Lee Ye-bin's version will be presented on September 10, Cheon So-yoon's version on September 11, and the full version on September 12. The TV commercial is scheduled for release on September 15.
The three cheerleaders will also appear in the in-game cheerleader content of '2026 Professional Baseball GO!'. Players can collect and assemble cheerleader photo fragments in the game to boost their team's power.
