The starting pitcher for the second game against Japan for the Korean baseball team was Jung Woo-joo.

South Korea announced the selection of the second leg on the 16th ahead of the first leg of the "2025 NAVER K-BASEBALL SERIES" warm-up match against Japan on the 15th. South Korean coach Ryu Ji-hyun chose Kwak Bin as the first game selection, but the second game, which was shrouded in mystery, was Jung Woo-joo of the Hanwha Eagles.

Jung Woo-joo, the second-ranked high school graduate rookie in the first round this year, mainly played as a bullpen pitcher in Hanwha. He pitched in 51 games in the regular league and posted a comprehensive record of 3 wins and 3 holds with a 2.85 ERA.




He also has experience in selection. He took the mound twice as a starting pitcher at the end of the season.

In his first start against Kiwoom in Daejeon on September 15, he allowed three hits, two walks, four strikeouts and two runs in two ⅓ innings, and in Daejeon LG on September 29, he pitched well with one hit and three strikeouts in three ⅓ innings. This year, he did not prepare as a starter, but showed stable pitching even though the number of pitches was limited to around 50.

Jung Woo-joo's start continued in the playoffs. As Moon Dong-joo, the fourth starter, started as a bullpen pitcher, Jung Woo-joo started Game 4. Jung Woo-joo threw 67 pitches at the time, preventing three ⅓ innings with three hits, one walk, and five strikeouts.

The limit number of pitchers in the first round of the WBC is 65, and there is no limit on the number of pitches in this warm-up match, but considering the WBC, Jung Woo-joo is likely to be a starter.

Jung Woo-joo mixes fast balls, curves, and sliders in the mid-150km range. In the playoff against Samsung, the maximum fastball speed came out to 154km, and 43 fastballs and 12 curves and sliders each out of 67 were added.

In the warm-up match against the Czech Republic at Gocheok Dome on the 9th, Kim Seo-hyun took the mound in the bottom of the 5th inning and blocked the first ⅓ inning with no hits, three strikeouts and no runs. He threw 20 balls, and the maximum fastball speed was 153 kilometers.




I wonder if the high school graduate rookie pitcher, who threw confidently in Korea, can confidently throw the ball at the Tokyo Dome of 50,000 people.
