Until the 5th inning, the two pitchers had a dazzling battle between the two pitchers.
Woo-jin Ahn performed a strikeout show with a high-speed ball with a maximum speed of 157 km/h and a sharp slider, and Chang-mo Koo, with his blade-like control, as a weapon.
Goo Chang-mo, who allowed a walk in the 6th inning and reached 98 pitches, was replaced first, where the NC Gu Gu-jin allowed a just-in-time hit and the balance of 0 was broken.
Ahn Woo-jin, who had the lead on his back, gave even more strength.
He also appeared in the ninth inning for the first time in a starting game and struck out Son Asop, finishing his career-high 8 and one-third innings scoreless pitching.
Ahn Woo-jin, who reached the 10-win mark for the first time in his career, captured a personal tie-breaking 11 strikeouts, placing him in a tie for number one strikeouts.
2nd place Kiwoom went on to win three straight games, but the lead SSG did not allow a chase.
Starter Won-seok Oh faced only one batter in the first inning and was replaced due to back pain, but the second pitcher Min-Jun Choi's hot pitch and Shin-Soo Choo and Jae-Won Lee's home runs took the lead to defeat Samsung.
Samsung rookie Hyun-Jun Kim hit a right-handed hit in the fifth inning, increasing the hitting record for players under the age of 20 to 21 games in a row.
LG Kelly, the sole leader in multiple wins, had a chance to achieve 12 wins in the season with six scoreless innings before Doosan.
Lotte beat KT with starting pitcher Park Se-woong and Ko Seung-min's consecutive home run.
