LG Twins rookie pitcher Kim Young-woo threw a 157-kilometer fastball in his professional debut. 

The game between the LG Twins and the NC Dinos took place at Changwon NC Park on Sunday local time. Kim took the mound in the bottom of the ninth inning when LG led 14-4 on the day. Changwon NC Park sold out 17,943 players on the day. It was his first appearance in front of a packed audience. Manager Yeom Kyung-yeop has been waiting for Kim to take the mound in the most comfortable situation. 

Kim threw a 150-km first pitch off Kwon Hee-dong, his first batter. He was fouled with a fastball of 153 kilometers on two pitches and a fastball of 154 kilometers on three pitches, and he swung and missed with a fastball of 157 kilometers on the fourth pitch. As the electronic display showed his 157-km speed limit, crowded spectators at Changwon NC Park exclaimed, "Wow!" 메이저놀이터

Afterwards, he threw a fastball to Seo Ho-cheol, but allowed a hit to left. He swung Park Se-hyuk with a 134-km folk ball, striking out two. Kim Hui-jip, who hit a homer on the day, ended the game with a slider and foul fly to the third baseman. 

After the game, Kim Young-woo said, "I think it's a great experience just to be in the first team entry, and I'm so thankful that I got the opportunity to make my debut. I'm glad I did better than I thought. I went up to the mound and pitched, and I was overwhelmed to hear the fans' chants," he said. 

"When I get the chance, I really want to grab it. Outside the game, they kept cheering me on and telling me a lot of good things so that I could be comfortable. Thank you so much," he said. 

Kim himself was surprised at the maximum speed of 157 kilometers per hour. "I didn't even expect a speed limit as the weather was cold (recorded 157 kilometers). I didn't know I got 157 kilometers per hour. I threw more balls thanks to fans' cheering, and I think I gained more speed because the coach and coach conducted mechanical inspections after the exhibition game. I think I was able to throw better pitches if I continue to make improvements to my capabilities," Kim said. 

When asked if the 157-kilometer speed is the best, Kim Young-woo said with a smile, "It's the best speed in my life." 

Finally, Kim Young-woo said to his fans, "Thanks to your support, I think I made my debut well. In the future, I will repay you with a player who gets better and better by filling in the shortcomings," he said.
