Veteran Kim Jae-hyun of Kiwoom Heroes ignited Gocheok Dome into a cauldron of excitement by hitting a walk-off grand slam home run, an unprecedented feat after 4 years (1,551 days).

On the 23rd, Kiwoom secured a dramatic 8-7 victory in their home game against KIA Tigers at Seoul Gocheok Sky Dome during the '2026 Shinhan SOL KBO League', scoring six runs in the bottom of the 9th inning to complete a stunning comeback.

The hero of the day was undoubtedly Kim Jae-hyun. Trailing 2-7, Kiwoom narrowed the gap to 4-7 with a two-run single by Davidson after consecutive hits by Kwon Hyuk-bin, Seo Geon-chang, and Choo Jae-hyun in the bottom of the 9th with one out and the bases loaded.

Kim Jae-hyun then stepped up to the plate and launched a walk-off grand slam home run off KIA relief pitcher Lee Ui-ri, sealing the victory. This was Kim's 8th career home run, his first in 4 years (1,551 days) since May 25, 2022, against LG at Jamsil.

Rare records poured out as well. Kim Jae-hyun's home run was recorded as the 26th walk-off bases-loaded home run in KBO history. It is also Kiwoom's second of the season, following Ahn Chi-hong's bases-loaded home run against KT at Gocheok on May 10. For Kim personally, it marked his first career walk-off home run (6th of the season, 388th career) and his first bases-loaded home run (32nd of the season, 1,154th career), achieved in the most dramatic moment.

After the game, Kiwoom manager Seol Jong-jin praised, "Starting pitcher Jeon Jun-pyo pitched well again today after yesterday's game. It is encouraging to see him improve with each game." He added, "The lineup showed focus and never gave up until the end. Davidson hit a two-run single in the 9th inning following his home run in the 3rd, setting the stage for the comeback, and veteran Kim Jae-hyun's walk-off grand slam home run led the team to victory."

Regarding Seo Geon-chang, who recorded three hits, Seol said, "I sincerely congratulate him on achieving 100 hits in a season for the first time in five years." He then added, "Today's victory was possible thanks to all the fans who gave us their unwavering support. I am truly grateful."
