Ha Hyun-seung's record of consecutive strikeouts during his freshman year

This is an old video from Lee Dae-ho's YouTube channel.
There is a brief appearance of Ha Hyun-seung from Busan High School, who is about to move from his freshman to sophomore year.
It says that just two months after he started pitching, he played for the Lotte team and set a record of 15 consecutive strikeouts against Kyungnam High School.
However, it seems like this record was compiled over two games.
Lee Dae-ho commented that he has a great downward angle from his tall stature and good control.
When asked how tall he is, he said himself that he is 194cm. (There are also rumors he is 197cm now?)
But he mentioned that if you ask any player, they all want to be pitchers at this age.
For example, even a player who is the batting champion in a tournament might actually want to be a pitcher lol.
The interesting part is that Ha Hyun-seung was a player that MLB wanted to recruit as a hitter rather than a pitcher.
It feels like an all-time legendary talent has appeared.
Personally, I want to see him succeed as a hitter. I want to see a Korean player achieve even better results than Choo Shin-soo in the MLB.
