Born in 1969, 54-year-old Hanwha legend Dae-seong Koo returned to the mound.



He appeared in an Australian League game after four years and showed an incredible pitch.



In the 8th inning, this pitcher appears with an expression full of excitement.



This is 54-year-old Koo Dae-sung, who was called the 'Daeseong Undefeated'.



His unique and demanding pitching form is still the same.



The 22-year-old, younger than his own son, struck out the first batter on a swing.



Amid the enthusiastic support of his teammates, his son-in-law, the next hitter hit the shortstop grounder and the last hitter struck out, ending his first comeback in four years with a scoreless pitch.



Gu Dae-seong, who sighed slightly as if he was nervous, broke the record for the oldest appearance in the Australian League.
