HAEGIN confirmed on the 21st that the latest periodic update for 2026 Pro Baseball GO! has officially landed. This rollout brings the new 'FA Season' card tier to the table, alongside a fresh lineup of cheerleaders and seven new uniform styles, all aimed at sharpening the experience for those obsessing over team management.

The new FA Season cards are composed of star players who made high-profile free agent moves between 2020 and 2025, including Yang Eui-ji, Na Sung-bum, Kang Baek-ho, Son Ah-seop, and Kim Hyun-soo. The key feature of these cards is that they can simultaneously apply the team deck effects of both the player's previous and current clubs. This allows users to experiment with much more versatile team deck strategies than before.

For the fans, popular cheerleaders Seo Hyun-sook of the Doosan Bears and Lee Ye-bin of the kt wiz are joining the game’s roster. The real-time text commentary system has also been overhauled, allowing users to track not just their own team’s match but also the status of other KBO stadium games at a glance. A button to jump directly to the broadcast page has been added to the main screen.

Additionally, seven new uniforms have been added, including the KBO 40th Anniversary collection, Dream and Nanum All-Star jerseys, and championship kits for the KIA Tigers and LG Twins. Beyond the cosmetics, the update expands the 2020-2025 regular season hard stages and the Star 2 league tier, while introducing position training up to level 10 and a new SSS-grade effect.

To celebrate the update, HAEGIN is rolling out a suite of events. These include a summer vacation exchange event to acquire power-up items, a special giveaway of legendary cheerleader packs for Liberation Day, various missions for Baseball Day, and match prediction events.
