Doosan Bears' fifth starting pitcher Kim Yu-seong (23) took the examination. Doosan manager Lee Seung-yeop said, "Kim Yu-seong must overcome his fight with him first."먹튀검증

Kim started the game against the LG Twins in the "2025 KBO League" held in Jamsil on Wednesday, and was replaced in less than the fourth inning. Kim was out after allowing two runs in three ⅔ innings. As his team lost 0-4, Kim suffered a humiliating loss. He now has two losses and an earned run average (ERA) of 9.90 without a win in four games this season. Kim garnered trust from coach Lee Seung-yeop by throwing 154 kilometers in the spring camp, but has another problem.

"Ball" was the cause of concern. Kim Yu-seong gave three walks on the day. Rather, he gave two walks in the bottom of the first inning but held on well. The fourth inning was regrettable.

In the bottom of the fourth inning when the score was 0-0, Kim faced Moon Bo-kyung with one out and one on the first base. He garnered two strikes first to secure an advantageous count. Moon was not fooled by the 5th pitch he threw in the 2nd strike and 1 ball. In the check swing scene, he was judged that the bat did not turn.

Since then, Kim Yoo-sung has thrown two balls, causing a crisis on his own. The walk has piled up runners.

Kim Yoo-sung also failed to finish by catching two strikes first in the match against Oh Ji-hwan. He was dragged to two strikes and gave up a timely hit.

Kim Yoo-sung failed to regain stability by hitting Park Dong-won's side.

When the base was full, the Doosan bench moved quickly despite being one point behind in the fourth inning.

Kim Yoo-sung is actually a pitcher who had a lot of control.

However, he was evaluated to have significantly improved this weakness through training and exhibition games he played ahead of this season.

He competed with Choi Won-joon until the end for the fifth starting position.

Manager Lee Seung-yeop expected the fastball pitcher to exert more power because it was early in the season. Even while asking Choi Won-joon for understanding, he used Kim Yoo-sung as a starting pitcher.

Kim Yoo-sung is getting more and more balls as he enters the regular season.

Rather, he pitched best against KT on March 27, when he first took the mound. At that time, he allowed four runs and lost five innings, but had only one walk. He deserved a high score for himself as he allowed seven strikeouts and allowed five innings as a fifth starter.

It was the second game against Kiwoom in this season when Kim took the mound as relief pitcher to maintain sense of play in actual games. Kim gave walks to both batters on the day. The Lotte Giants also showed poor performance in allowing three walks and five runs in one ⅓ inning on Sunday.

"As I always tell you, if Kim Yu-seong throws more balls in the strike zone, he can become a very good pitcher. Since he constantly loses to himself before fighting against his opponent, he often collapses even without being able to compete against his opponent," coach Lee Seung-yeop said ahead of the match. "I think that's the key point."

After all, it is about confidence. "It is important how much you can throw your ball on the mound without being intimidated. If you throw it with the mindset that you are the best, I think it will be different. "I don't think I can demonstrate even one-tenth of my current ball power," he said.

He already proved his capability. "We need to instill confidence in Yoo as well. He has great potential," coach Lee Seung-yeop said in expressing expectations.
