Go Woo-suk, a right-hander from Galsan Elementary School, Yangcheon Middle School, and Chungam High School, was a former promising player who joined LG in 2017 as the first draft pick. Despite his short stature, he was recognized as the "second Oh Seung-hwan" for his fiery fastball, which came from his reliable physique. As expected, Go has grown. In 2019, when he became a professional in his third year, he made 35 saves, becoming the closer to LG, succeeding Kim Yong-soo, Sanghoon Lee, and Bong Jung-geun. He became the first relief pitcher with 42 saves in 2022 after making 30 saves in 2021. His 40 saves were the first for an LG team, and he was also the youngest ever to make 40 saves, surpassing Oh Seung-hwan from Samsung in 2006 24 years, 1 month, and 26 days.

His overall performance in the seven seasons was 19 wins, 26 losses, 139 saves, six holds, an ERA of 3.18 strikeouts and 401. Last year, he suffered from shoulder pain during pre-season WBC practice games, and was somewhat sluggish with 44 games 44 innings with 3-8 losses and 15 saves with an ERA of 3.68. Ko, who also showed signs of nervousness in the Korean Series, ended with a happy ending as he marked the last moment of winning Game 5, but his performance in the Major League was not as good as in previous years.

However, Ko boldly challenged himself to post, and successfully secured a $4.5 million contract with San Diego with a two-year guarantee. He has also been recognized for his consistent performance in the national team. Starting with the WBSC Premier 12 in 2019, he has earned his national team the title at the 2021 Tokyo Olympics, the 2023 WBC, and the Hangzhou Asian Games. In particular, he benefited from the gold medal at the Hangzhou Asian Games, laying the foundation for his advance into the Major League.

Oh made his big league debut with the St. Louis Cardinals in 2016 at the age of 34 after playing for the Hanshin Tigers in Japanese pro baseball. Since then, he has played for the Toronto Blue Jays and Colorado Rockies with a total of 232 games 225 ⅔ innings, 16 wins, 13 losses, 42 saves, 45 holds, 3.31 strikeouts, and 252 strikeouts. He spent his best season in his first year in 2019 with 76 games 79 ⅔ innings, 6 wins, 3 losses, 19 saves, 14 holds, and 103 strikeouts, and succeeded in making 20 saves in 2017. Although he showed enough competitiveness, it remains regrettable that he advanced to the mound late in his mid-30s. Attention is focusing on whether Ko Woo-seok, who took the mound in the Major League at the age of eight years younger than Oh Seung-hwan, will be able to surpass his idol. 안전놀이터 추천
