Coach Lee Seung-yeop also tied for the most consecutive victories among rookie coaches in Korea.
The professional baseball Doosan Bears won 10 straight wins at the start of the second half and tied the record for the most consecutive wins by a team.
Doosan defeated the KIA Tigers 5-2 at the Gwangju Kia Champions Field on the 21st.
Doosan, who won all 10 matches this month alone, recorded 10 consecutive wins, the most in the team, following in 2000 under former manager Kim In-shik and in 2018 under former manager Kim Tae-hyung.
Coach Lee Seung-yeop, a new Korean coach, achieved 10 consecutive victories in the fourth year following former LG Twins coach Cheon Bo-seong in 1997, former Hanwha Eagles coach Lee Hee-soo in 1999, and former LG coach Lee Gwang-eun in 2000.
When foreign players are included, former Lotte Giants coach Jerry Royster won 11 consecutive wins in 2008, setting the record for the most consecutive wins in his first year in office, covering domestic and foreign coaches.
If Doosan and coach Lee Seung-yeop win the next game, they will set a new record.
In the ace match between Raul Alcantara (Doosan) and Mario Sanchez (KIA), Sanchez collapsed first.
When KIA tied Socrates Brito's double and Lee Woo-sung's right-handed hit at the end of the second inning to score the first run, Doosan tied the game 1-1 with Jose Rojas' superior home run in the bottom of the fifth inning.
Rojas struck out 8 strikeouts and hit Sanchez, who was struggling without a run, with a home run to turn the game around.
In the 6th inning, Heo Gyeong-min drew a left-handed solo arch, turning 2-1 after 2 outs.
Sanchez, who posted an ERA of 1.44 with 8 wins and 1 loss in the first half of this year's Taiwanese professional baseball before moving to KIA, and allowed only two home runs in 62⅔ innings, has already hit three home runs in two games in the KBO League.
Doosan, who had the chance to win, split the win with a concentrated attack in the 7th inning.
Yang Seok-hwan's double and Rojas' walk created a chance, and Park Gye-beom, a pinch hitter, hit the base with a ball from KIA relief pitcher Choi Ji-min in the 2nd 1st and 2nd base.
Park Joon-Young, one of the top contributors to Doosan’s winning streak, fouled Choi Ji-Min’s fast ball three times in a row, then hit a sweeping triple through the right-center, delighting manager Lee Seung-Yeop.
Sanchez's earned run, which was strong from 2nd 1st and 2nd base, increased to 4 points.
KIA only made up for one run with Socrates' home run in the 8th inning.
