What is a fatigue fracture.

Why did the player, who was mentioned as the first overall candidate, fall to the eighth place.

2026 KBO Rookie Draft held on the 17th. The best topic of the day was not Park Joon-hyun (Bukil High School), who was selected as the No. 1 overall pick for the Kiwoom Heroes.




Yang Woo-jin, a former Gyeonggi Aviation High School pitcher who was selected by the LG Twins as the eighth in the first round.

Why was it a hot topic. Yang Woo-jin was initially expected to receive the Kiwoom nomination as the No. 1 overall pick. The pitcher's attractive feature is a fastball over 150 kilometers from his healthy build, which measures 1 meter 90 meters and 100 kilograms. He said he would throw a sweeper, which was hardly an enemy in high school.

Of course, three people, Park Joon-hyun, Kim Sung-joon (Gwangju Il High School), and Seo Moon-joon (Jang Chung High School), received more attention. However, as all three declared their challenge to the U.S. Major League, the spotlight was naturally focused on Yang Woo-jin, who took the next turn.

With Park Joon-hyun suddenly withdrawing his intention to go to the U.S. and choosing the KBO League, Yang Woo-jin was expected to be nominated as the second-ranked NC Dinos. However, there was an unusual atmosphere ahead of the draft. Rumors began to spread that NC and the third-ranked Hanwha Eagles were not considering Yang Woo-jin. There were good fielders such as Shin Jae-in, Oh Jae-won (Lee Sang-go), and there was also a reason why Yang Woo-jin's elbow fatigue fracture was confirmed.

Still, it was expected that he would be picked unconditionally in the middle of the first round, but subordinated teams also chose pitchers other than fielders and walked Yang Woo-jin. As such, he was nominated by LG in the eighth place.

What's going on. A club official tipped "It seems that all clubs before LG thought of Koo Chang-mo (NC)." Koo Chang-mo is NC's left-hander ace, but he has a strong image of 'glass body'. In particular, recently, a fracture of elbow fatigue bothered him. Since Koo Chang-mo signed a total of 13.2 billion won contract, I understand that NC passed because it was nervous just by hearing the word "fatigue fracture," but I didn't know that other clubs would make the same choice.




Then, what is a fatigue fracture. To put it simply, it is a disease that collides with bones when using the area, incontinence occurs, and pain is caused. If it is a complete fracture, it is cured if the bone sticks, and the problem with fatigue fractures is that it recovers after a considerable period of rest, but it is more likely to recur. One training expert said "In the case of a pitcher, an elbow impact is caused by a certain pitching motion, resulting in a fatigue fracture. However, if the pitching form is not changed, the probability of recurrence is very high. Even so, it is difficult to change the pitching form without hesitation. Not only is it difficult for the player to adapt, but his ball power may drop." Many clubs are likely to have skipped Yang Woo-jin after seeing the probability of recurrence.

What will be LG's choice. It is said that it is impossible to predict when fatigue fracture injuries occur, how quickly they recover, and when they will occur. Recently, Samsung Lions' Lee Seung-hyun (left-hander) was declared out-of-class for the season due to a fatigue fracture, but there are cases where he returned earlier than expected. However, it is undeniable that the ball power has dropped sharply.
